[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I don't see this to be fixed in the 9.10 iso I downloaded and installed this week. I have tried to install it from a CD and USB stick, but both fail to boot after the initial restart at the completion of setup. The hardware I'm installing on doesn't have an onboard CD so it's impossible for the boot order to remain the same as during setup. I've tried tweaking it every way possible and removing all bootable options except the HDD and I'm still in the same boat. Any ideas? I'd like to get this going. Thank you.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I don't think this will be fixed .. The new LTS will most likely use the search-for-disk-with-uuid-x and set that as ROOT if found mechanism from the new grub releases. Easiest way for now is to first live edit the config at first regular boot after install (set root(x,y) to whatever you need it to be), then delete /boot/grub/menu.lst and run update-grub again .. .. and don't change the BIOS boot order from that point onward ..

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I believe that this situation still exists with 8.04 (which as LTS I'm trying to install). I don't have a CD drive, so i'm installing from a USB key. The BIOS on the Sun x2200 sees the usb key as a type of hard disk. During install it is registered as /dev/sda, with the (single) SATA disk as /dev/hdb. Of course after I remove the USB key the order of the disks changes in the BIOS (since the usb key is not present). This results in the Grub Error 22. Rescue mode grub reinstall does nothing to fix this. Will the fix discussed in #90 be backported to 8.04? -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Once you have an incorrectly-generated /boot/grub/menu.lst, 'update- grub' will still take defaults from that. Then, to get rid of this problem, simply remove (or just move) /boot/grub/menu.lst and have 'update-grub' generate an entirely new one. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I am not sure whether this bug is supposed to have been fixed or not, but it is still present in the main release of 8.04 and I can document pretty much exactly what happens. I have an Asus P4C800-E motherboard with 2 identical 160 GB Samsung disks (D1 D2) attached to the main SATA controller, and 2 identical 300 GB Samsung disks (D3 D4) attached to the Promise SATA controller. The pair attached to the Promise SATA controller are configured as a RAID 1 (mirrored) array. The BIOS is set up to boot from D1 with a boot order D1, D2 D3/D4. This worked fine with Ubuntu 7.10, except that the RAID array was ignored. I had Ubuntu installed on D2 and Windows XP on D1 with the grub boot loader in the boot record of D1. When installing Ubuntu 8.04 either grub or Ubuntu identifies the disks in a different order - D3=(hd0)=/dev/sda, D4=(hd1)=/dev/sdb, D1=(hd2)=/dev/sdc, and D2=(hd3)=/dev/sdd. I have installed Ubuntu in the primary partition of D2. Whether through the automatic installation or manually, grub insists on identifying this partition as (hd3,0) and the menu.lst file reflects this. The automatic installation puts the grub boot loader in the mbr of (hd0), i.e. D3. Manually, I can put the grub boot loader in the mbr of (hd2), i.e. D1. Now, I have the grub boot loader on both D1 and D3, but it insists on looking for Stage 2 on partition (hd3,0). As a result it falls over reporting Error 21 - because the BIOS is telling it that (hd3,0) doesn't exist as D3 D4 are mirrored as (presumably) (hd2). This is the outcome when I leave the boot order as D1, D2, D3/D4 or if I change it to D3/D4, D1, D2. I have no doubt that if I sacrifice the RAID array, then things can be made to work properly, but only at the cost of losing my disk mirroring. The previous advice about editing the menu.lst file doesn't help, because the basic problem lies in the setup that is written to the mbr because of the misidentification of the disk array order by grub. I should emphasise that this appears to be a generic grub problem as I have encountered exactly the same problem in trying to install both Mandriva 2008.1 and OpenSUSE 11.0. All of them create an erroneous boot loader that falls over in one way or another - sometimes the error number is 21, sometimes it is 22 - as well as a version of menu.lst that would have to be edited. As additional information, I am not using WUBI to install Ubuntu and I can replicate the behaviour. Finally, as a matter of considerable frustration, the problem was introduced when I tried to upgrade from my 7.10 setup to 8.04, with the result that a properly functioning setup has been completely destroyed. This is the worst aspect and, in my view, is simply inexcusable since upgrades should never render a system unusable.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
Here's a workaround at least for my case without any severe modification of the system. 1: Make sure the bootloader is installed on the boot HD whether it works right or not. Manually install if you have to with find root and setup in grub off the live cd (I'm not putting those instructions here myself but they're easy to find) 2: Boot to the bootloader which will fail because the menu was configured wrong. Use the GRUB command line and the built in editor to find out what the real hd#'s are, using trial and error for windows (I recommend changing root to rootnoverify and deleting the maps if windows is on hd0) and find /boot/grub/stage1 for ubuntu. Write these down. 3: Use GRUB's built in editor to temporarily fix the boot menu option for Ubuntu and boot it. 4: In Ubuntu edit /boot/grub/menu.lst and manually fix the boot menu options to the hd#s as they are on boot. 5: Manually install the GRUB bootloader as in 1, ignore the fact that the hd#'s are different than they are at boot, the menu.lst is already fixed this is just to get the bootloader updated. 6: Reboot and test. Here's my own config: Asus A7N8X-E with an add-on PATA card (I'm too lazy to find out which).

Running Gigabyte GA-81EXP with 2 channels of onboard IDE and channels of Promise IDE has this same problem. Up until last night I was running 7.10 and the controllers booted up randomly. If they came up backwards I could just reboot a couple of times until everything mounted correctly. Upgraded to 8.04 last night and now it's permanently backwards. The first drive on the system comes up as /dev/hdc, but only because I have two drives on the Promise controller. The moment I add another drive the boot disk will become /dev/hdd, and so on.

Hello, is this really fixed? I came here from https://wiki.ubuntu.com/WubiGuide and had this error today installing Ubuntu 8.04 with Wubi. All went well until the second restart (the one after installation from within Ubuntu), and I got Error 15 on all entries including Windows, which was quite scary, and a pretty nasty bug. I had to follow the instructions: You have to change all the lines root (hdX,Y)/ubuntu/disks to root ()/ubuntu/disks. Also edit the line that starts with #groot=(hdX,Y)/ubuntu/disks to #groot=()/ubuntu/disks. After that it worked fine, luckily I was able to discover this, but for someone not already familiar with Ubuntu this could be pretty traumatic.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
Colin, one has to boot with edd=on for this to be activated, as you say, and it's presumably defaults to off for good reason, This option is experimental and is known to fail to boot on some obscure configurations. says drivers/firmware/Kconfig. However, I'd guess that grub only makes use of the MBR's four-byte Windows NT signature at offset 440 in the MBR which is published in /sys/.../int13_dev80/mbr_signature. Since reading the MBR is done in arch/x86/boot/edd.c:read_mbr() by using INT 0x13 AX=0x201 (read legacy sector) it will work without doing any EDD-specific stuff which may stop booting on some obscure configurations. If query_edd() in the same file didn't avoid reading the MBRs when (!do_edd do_mbr) then the data could still be published by /sys for grub to use. This would allow EDD to not be done by default, avoiding boot problems on some machines, but BIOS device 0x80's MBR's EDD ID would be available to grub on all machines without the user first having to suffer problems, then find out that the resolution is to add edd=on to the kernel's parameters. What do you think? The current fix of insisting EDD be done before four bytes of the MBR can be published seems limiting and allows more users to be pestered by this issue in the future instead of them never knowing it existed. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 8497] Re: grub guessed BIOS disk order incorrectly
Having spoke to Matt Domsch, EDD kernel support's author, it seems it's the reading of the MBR that's typically causes booting problems when the drive being read doesn't exist. So there's no point doing just the MBRs and ignoring the advanced BIOS calls in the hope that it could be enabled by default. I've suggested to Matt that maybe 0x0040:0x0075 (BIOS's opinion on number of hard drives) could be read and used as a limit if it looks sane. Anything we can do to increase the number of machines EDD can run on without causing problems would help. BTW, when grub is examing the MBR signatures and realises some aren't unique, it doesn't issue any diagnostic to that affect. It's possible the user would be happy to make them unique using, e.g. fdisk's expert's `i' command, but it should be drawn to their attention.

I'm having the same problem: Configuration: 2 disks (IDE and SATA). Bios sets the IDE disk as the first disk (default option) and I've changed this to the SATA one.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
Sounds like this might be related to my problem at http://ubuntuforums.org/showthread.php?t=668639. Not only did GRUB install itself to hd2 (needs to be changed to hd0 to boot) but the kernel typically enumerates the SATA drives in a completely different order every time. If fstab wasn't using UUID's I'd be utterly hosed... When installed, GRUB picks up the drive precedence correctly from the BIOS, but the kernel doesn't. I'm mulling over writing a bunch of udev rules in order to get a consistently sane device mapping going but would prefer trying out a possible fix first. As I think I said in the forum, it looks to me like the LiveCD GRUB is basing its detection on what the running kernel has read the drives as, whereas the installed GRUB bases its information on what it gets directly from the BIOS, but the kernel/udev that boots then also wrongly detects the drive order (and in an inconsistent fashion too). Could easily turn into a very nasty problem for people like me with many hard drives or, heaven fobid, people with removable hard drives (again like me ;)).

Hum, I think I have read too fast. Seems like bug #15213 (that was 8899 in bugzilla time) was indeed fixed by deactivating CONFIG_EDD.

A number of comments posted here are unrelated to this bug report. If you get to a grub menu, then this bug report is not related to your problem. Having the kernel not be able to find the root filesystem because it changed name and you weren't using the UUID is a separate issue. Devices changing names across kernel upgrades or even just reboots is considered upstream to be not an issue and won't be fixed.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
My experience with this issue is a little different. The system is a file server running 6.06 LTS There are five HD's Boot and OS disk is attached to the MB Pri Master. This disk has always been HDA Partitions are: hda1 = boot hda5 = root hda6 = home There are four MDRaid disks on a SIL controller. These disks have always been HDE, F, G, H The system was removed from service back when the kernel was at - /vmlinuz-2.6.12-10-386. Today we refired the system, did a apt-get update, upgrade, dist- upgrade. The default kernel is now - /vmlinuz-2.6.15-29-386 The system now fails to complete a boot cycle, dropping to the shell. Indicates /dev/hda5 does not exist. Booting with the older kernel works fine. Booting with the current kernel indicates that the onboard controller is now located at HDE and the SIL controller is now HDA, B, C, D. This problem is a MAJOR problem and a showstopper for Ubuntu. How can anyone trust Ubuntu Server when a kernel upgrade changes something like HD detection order and effectively kills a system. It's not the BIOS as this system worked fine since the early release of 6.06. It has been updated several times. Sometime changed in Grub or the Kernel. I have another system running Fiesty that randomly changes the assigned drive order with a 3ware sata raid card. This does not effect the booting, but it makes auto mounting of the array impossible. After every boot cycle we have to check which order has been assigned and manually mount the array. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Colin, I'm taking the imposition of assigning this to you because many of the duplicates were and it seems to need someone to move it forward. I thought you'd know who that should be. Also, https://wiki.ubuntu.com/Bugs/Importance says an Importance of High is for a bug that Has a severe impact on a small portion of Ubuntu users. This bug stops systems booting for a small, but growing, number of users. It also says Makes a default Ubuntu installation generally unusable for some users... for example the system fails to boot. I think that's also true so can you please up the Importance from the default Medium to High. Even if it makes no difference to when the bug is fixed, it would act as a comforter to those of us bitten by it. :-) http://lwn.net/Articles/12334/ has a good summary of the problem: x86 systems suffer from a disconnect between what BIOS believes is the boot disk, and what Linux thinks BIOS thinks is the boot disk. This manifests itself in multi-disk systems - it's quite possible to install a distribution, only to fail on reboot - the disk installed to is not the disk BIOS is booting from. Dell restricts our possible standard factory installed Linux offerings to disks on no more than one controller to avoid this problem, but mechanisms now exist to solve it and allow such configurations. This bug is, as predicted, biting not just those doing a fresh install, possibly for the first time, how off-putting!, but also those upgrading from 7.04. ** Changed in: grub (Ubuntu) Assignee: (unassigned) = Colin Watson (kamion) -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 8497] Re: grub guessed BIOS disk order incorrectly
This is STILL an issue in GUTSY and can create an UN-BOOTABLE SYSTEM that's very difficult to debug. Ubuntu (or grub) simply doesn't have the same idea of disk ordering as the BIOS. In particular this is what just happened to me with a new Gutsy install. After installation and reboot the computer just said Grub stage 1.5 and Error 15. That error apparently means it couldn't parse a number, which is pretty much a useless error. After spending about 2 hours on the problem, I realised that grub had installed itself on hd0, according to Ubuntu, but actually the second disk according to the BIOS. The computer was happy to boot from the second disk, but when grub then ran I can only assume it thought it was on the first disk and subsequently read information from that disk which didn't have the grub-stuff installed. And it broke. I made it all work by physically shifting the disk connections around to make the boot disk was the first in the BIOS sequence (but detected as *hd2* by Ubuntu) and reinstalling (just to be sure). -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sometimes it helps to engage brain before putting mouth into gear!

If you're feeling particularly adventurous you could build the kernel EDD module. 1.

A follow-up to my observations of the SCSI address allocation. It looks as if this is determined in drivers/ata/libata-core.c::ata_host_register() where, in part, you find /* print per-port info to dmesg */ and in turn calls drivers/ata/libata-scsi.c::ata_scsi_scan_host() It appears that each ATA port is assigned as a separate host adaptor which explains the addressing we are seeing.

These two comments suggest EDD is the right way to construct device.map: http://kerneltrap.org/node/6408 These days, you just cannot enumerate controllers in any meaningful manner. I don't think you ever really could, but at least with static hardware, any random enumeration was as good as any other. http://lwn.net/Articles/75923/ Say Y or M here if you want to enable BIOS Enhanced Disk Drive Services real mode BIOS calls to determine which disk BIOS tries boot from. This information is then exported via driverfs. This option is experimental, but believed to be safe, and most disk controller BIOS vendors do not yet implement this feature. Since the main purpose of device.map is to tell the stage1 GRUB code which disk to look on for the stage2, and the disk address seems to be resolved by the BIOS, we really need to be asking the BIOS for this information. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yeah, the Windows ones are supposed to be (channel, target, lun) or (controller, target, lun). I would have thought logically they would all have the same controller, but maybe SATA is handled differently. (0,0,0), (0,1,0), and (1,0,0) would map well to IDE primary master, IDE primary slave, IDE secondary master. Perhaps that's what it's doing as part of the legacy/PATA emulation? The addresses in Windows are almost certainly pretend ones.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
Mikel, thanks for those reports, they help clarify your circumstances tremendously. This is just off the top of my head without any real investigation, but the difference in the SCSI addresses between Windows and Linux makes me wonder about how the SCSI addressing is being determined. For Windows, the three-digit addresses are, I seem to recall, Channel, ID, LUN but the Linux addresses reported in the SCSI reports above show each device as a separate Host, with each Channel, ID, and LUN being 0,0,0. Linux will arbitrarily order the Hosts based on discovery order so on the face of it, we *seem* to be developing a somewhat plausible explanation for the issue. Here's a summary of what I'm thinking.

Ubuntu Linux 7.10 RC amd64
ASUS M2A-VM mainboard
Configured in PATA emulation mode so that Windows Vista works. (I'm not
sure what they called it on the BIOS settings, but it's the opposite of
AHCI mode. In Windows they show up under a generic ATA controller.)
Mainboard:
SATA4 (empty)
SATA2 Seagate ST380013AS 80 GB HD
SATA3 Seagate ST3250820AS 250 GB HD
SATA1 Seagate ST380817AS 80 GB HD
PATA1 LiteOn DVD-RW
(The physical ordering is weird! The front two connectors are red, the
back two are black. I assume the ordering is due to RAID. There is
only one PATA channel. I have no PATA hard drives, only the DVD drive.)
BIOS:
HDD1 Seagate ST380817AS 80 GB HD
HDD2 Seagate ST380013AS 80 GB HD
HDD3 Seagate ST3250820AS 250 GB HD
HDD4 None
Boot order is:
CD
HDD1
HDD2
etc.
Pretty sure that was the case during both installation and normal
operation. I changed it once to (CD, HDD2, HDD1) after Ubuntu wouldn't
boot. Doing this seemed to change Linux's device names, and it couldn't
find the root device. I changed it back. I don't think this has any
permanent effect.
Windows:
SCSI 0,0,0 Seagate ST380817AS 80 GB HD

SCSI 1,0,0 Seagate ST3250820AS 250 GB HD

(hd1) /dev/sdb
(hd2) /dev/sdc
corrected device.map:
(hd0) /dev/sda
(hd1) /dev/sdc
(hd2) /dev/sdb
This looks weird, but it's right since Linux detects HDD2 (what Grub
calls hd1) as /dev/sdc.

Will all those experiencing this bug with Gutsy give us detailed information as to the physical configuration of the motherboard disk interfaces and disk drives so we can understand the precise circumstances that cause this? Right now we have a combination of comments, some of which indicate an issue with the BIOS boot-order, others that the BIOS drive-detection reported order is different to that of Linux and/or GRUB. So, as an example: Asus A8V Mobo SATA-1 Drive-1 SATA-2 Drive-2 PATA-1-1 Drive-3 [master] PATA-1-2 Drive-4 [slave] PATA-2.1 DVD-1 [master] During Installation: BIOS boot order DVD-1 Drive-1 Master Boot Record (MBR), /boot partition /dev/sda5 Drive-3 root partition /dev/hd2 USB Linux (GRUB) Drive-1 /dev/sda (GRUB hd1) Drive-2 /devsdb (GRUB hd2) Drive-3 /dev/hda (GRUB hd3) Drive-4 /dev/hdb (GRUB hd4) DVD-1 /dev/scd0 Output of: $ ls -l /dev/disk/by-id After Installation: BIOS boot order Drive-1 Drive-3 DVD USB Linux (GRUB) Drive-1 /dev/sda (GRUB hd0) Drive-2 /devsdb (GRUB hd1) Drive-3 /dev/hda (GRUB hd2) Drive-4 /dev/hdb (GRUB hd3) DVD-1 /dev/scd0 Output of: $ ls -l /dev/disk/by-id -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think /proc/scsi/scsi is the simplest way to find out Linux has the order different: /proc/scsi$ cat scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST380817AS Rev: 3.42 Type: Direct-AccessANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST3250820AS Rev: 3.AA Type: Direct-AccessANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST380013AS Rev: 3.05 Type: Direct-AccessANSI SCSI revision: 05 Based on the BIOS ordering, scsi1 should probably be ST380013AS rather than ST3250820AS. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 8497] Re: grub guessed BIOS disk order incorrectly
My work around for this which I have been doing for some time is to just edit my Grub boot line, boot into Ubuntu then alter my menu.lst back to how it should be. The culprit for me is always the following line for each kernel listed: root(hd0,1) For whatever reason after a kernel update all entries are changed to root (hd1,1), changing back to the above fixes the problem each time. Perhaps a better approach is needed to updating the menu.lst file before more technical measures are attempted. If the script looked at what was already set and just mimicked it for the new kernel instead of guessing every time then this issue would go away. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think that this is serious.

I too fear that this is going to bite more people as their hardware moves over time away from PATA. Rendering a system unbootable is pretty severe and something that many users can't recover from un-aided. And how do they get that aid if the machine is their main Internet access? Can this bug's importance be re-considered? I can't see what options there are due to Launchpad's interface, but medium seems a bit low. And is grub definitely the right package? Lastly, can we have some feedback from those in the know about what course of action is intended to get this problem resolved?

I got bitten by this again in the Gutsy RC on my new PC. I posted my experiences here http://ubuntuforums.org/showthread.php?p=3518911#post3518911.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I am wondering if my bug #107249 is also being caused by this. In my case, kernel updates have sometimes failed and have resulted in the system presently being unbootable. My machine, an Asus A8V, reports 4 sata drives, two on each controller. Three of these drives are being used by linux: a bootable RAID-1 (3 disks), and a RAID-5 (3 disks) for data. The fourth drive contains a bootable XP partition. If lilo depends on a consistent ordering of the four drives, is it possible that the random reordering (as reported to linux by the bios) could have caused lilo to attempt to update a kernel on the XP drive instead of one from the linux array? -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks Val. I understand it can be corrected and worked around, but it takes a lot of perserverance to get to the point where you find a bug report like this one and discover the workaround.

I'm another person bitten by this. A system with PATA and SATA drives attempting to install on /dev/sda. The install goes fine and says it's finished but the BIOS fails to find any boot loader installed and wants a system disk inserted. Given the number of individual me toos on this bug, and that there are 13 duplicates, can its importance be bumped up a bit from medium.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
In my case the drive that is seen by grub as (hd1) when the system is running appears as (hd0) to grub during bootup. As a workaround I opened /boot/grub/menu.lst and changed the 'groot' line to rea: # groot=(hd0,0) Note that the line is supposed to stay commented out. The 'update-grub' tool actually reads these commented values when it is generating a new /boot/grub/menu.lst.

Probably my problem falls under the same category (Ubuntu 7.04, fresh installation): I have a pci IDE controller (Sil 0680 ATA) with two hard disks (master/slave) on it's 1st channel. I also have four hard disks on the onboard IDE controller (both channels) So, my normal setup is: Onboard IDE controler, primary channel, master: /dev/sda - boot disk, RAID1 (/dev/md0) Onboard IDE controller, primary channel, slave: /dev/sdb Onboard IDE controller, secondary channel, master: /dev/sdc - RAID1 (/dev/md0) Onboard IDE controller, secondary channel, slave: /dev/sdd PCI IDE controller, primary channel, master: /dev/sde PCI IDE controller, primary channel, slave: /dev/sdf The problem is that, randomly, the system boots with changed disk order, as follows: Onboard IDE controler, primary channel, master: /dev/sde* Onboard IDE controller, primary channel, slave: /dev/sdb Onboard IDE controller, secondary channel, master: /dev/sdc Onboard IDE controller, secondary channel, slave: /dev/sdd PCI IDE controller, primary channel, master: /dev/sda* PCI IDE controller, primary channel, slave: /dev/sdf It only affects the drives marked with *, nothing else.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I would like to add my experience here: upgraded a running ubuntu 6.x to 7.04. This caused an unbootable system, so I reinstalled 7.04. I got an error 15 from grub. Problem was that the disk order was different depending on if I booted with the install CD or without the CD. I have 3 disks: 1 - IDE /dev/hda my boot disk 2 - IDE /dev/hdc raid disk 3. SATA /dev/sda raid disk 4 IDE CDROM /dev/hdd The order of the disk is correct when installing or booting through the CD. The first disk hd0 = hda. The order of the ide drives switches after the install, and I get a an error 15 from grub. At the grub shell, hd1 becomes hda and hd0 is hdc. The strange thing (for me) was if I boot off the CD, then choose the last option of booting from the hard drive, the boot succeeds, implying the CD may have something to do with this whole mess. I've never had this problem before on this or other machines. I was able to work around it by changing the menu.lst and changing all the references of (hd0,0) to (hd1,0) but it seems I have to remember to do this everytime an upgrade updates menu.lst. -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

There is no way to detect how the bios sees the disks, and the bios may not see some disks at all. I think the fix for this is to have the installer notify the user that it is making its best guess as to how the bios sees the disks, but it may be wrong and if so, they will need to correct it.

[Bug 8497] Re: grub guessed BIOS disk order incorrectly
I'm curious if this bug is the same as what I see on my Abit AN8-32X system. I have 6 SATA drives (4 on an Nvidia chip, and 2 on Sil 3132 chip), 2 IDE drives (each a master on its own channel), and 2 USB drives, which are a SD and CF card reader. In Dapper, Edgy, and Fiesty, I see the set of 2 Sil 3132 chip drives floating in the boot order. On one boot, they appear as sdd and sde. On the next boot, they appear as sdf and sdg. It appears that the USB drives are not consistent about when the kernel detects them, and so they either appear before or after the two Sil 3132 SATA drives. When Edgy converted fstab to a UUID entry, I thought the misrepresentation of the drives would go away, but the problem manifested immediately after the Fiesty upgrade. Granted, I only had to reboot a few times between Edgy and Fiesty.
