In the end, after many machinations, neither MBR or UEFI would install, always hanging at "installing boot partition". As I mentioned, I opened a bugzilla for this, https://bugzilla.redhat.com/show_bug.cgi?id=1714828 which is still unresolved. The latest rawhide version, 20190604, still exhibits this issue. So, I downloaded the equivalent F30 netinstall image, and it installed a minimal UEFI install flawlessly. It boots fine, so I could stop here, and just turn on the rawhide repositories to get to F31, but I think I'll keep trying candidates from rawhide, at least for a while. ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

It either can read this FAT format EFI System partition to read EFI GRUB, or found your old BIOS GRUB. You can maybe determine which one from GRUB environment variables with the 'set' command.

But you're also dealing with multiple things all the same time. So it's sortof chaos theory at play that as you work through one problem you run into another one.

But to switch between them, you'd need to use the firmware boot manager; or efibootmgr prior to reboot time; or you need to modify both grub.cfg's on each drive's EFI system partition, to include a menu entry using the 'configfile' command to point at the other grub.cfg. That way, no matter which drive the firmware uses by default (as defined in NVRAM using 'efibootmgr' command) you have a GRUB menu entry to point to the other drive. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

Some firmware only boot CD's with CSM.

I cannot parse this at all into actual actions in the installer so I don't know what you're doing and can't tell if it's user error or a bug. What you still seem confused about is the installer itself has no control over whether the system is booted with UEFI or CSM/BIOS being presented. That is a firmware function, and it's selected at boot time. Once selected, the installer honors it and will only do an installation compatible with the current presentation of the firmware. After you boot installation media you can check what firmware is presented with # efibootmgr If entries appear, it's UEFI. If an error appears, it's CSM/BIOS. And if it's CSM/BIOS then defining a /boot/efi mount point is invalid. If you want a UEFI installation, it's mandatory that you figure out a way to boot the install media in UEFI mode. Even if it means you have to create a USB stick, and must abandon CD booting. > I give up for the time being. It's strange there isn't a switch that I > can set to explicitly tell it to install as UEFI. I can understand the confusion but it's not strange. It could be a badly designed user interface by the firmware manufacturer. And it's also possible you've found a firmware bug. You should make sure the firmware is on the latest revision available by the manufacturer. Quite a lot of bugs can be worked around by shim and GRUB but quite a lot of bugs can only be fixed by firmware updates. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

Each would have their own /boot/efi so they wouldn't step on each other. And just selecting a different disk to boot would select the different version of Fedora on that disk.

Fedora does put the grub.cfg on the EFI system partition at /boot/efi/EFI/fedora/grub.cfg - which is not how upstream does it. Upstream GRUB expects grub-install creates an EFI OSLoader binary that points to where GRUB stores its files which is /boot/grub (upstream doesn't tack on a '2' to everything, that's a Red Hat / Fedora convention). And hence much confusion ensued on Fedora, where to point grub2-mkconfig -o There are two symlinks on all Fedora installations: lrwxrwxrwx. 1 root root22 May 20 11:14 grub2.cfg -> ../boot/grub2/grub.cfg lrwxrwxrwx. 1 root root31 May 20 11:14 grub2-efi.cfg -> ../boot/efi/EFI/fedora/grub.cfg Blek. I don't like it. But that's the way it is. BLS files always go in /boot/loader/entries on Fedora - that is from the fully assembled file system and user space perspective. The original bootloaderspec just says $BOOT/loader/entries where $BOOT is the EFI system partition, but Fedora doesn't do that out of the box. You can retrofit it after installation to do it the systemd-boot way, and kernel-install supports it (I'm not sure if it only supports /boot as the mount point for the EFI system partition or also /efi) > The BLS files are probably in the /boot partition, same as the grub.cfg > now.

BLS files have limited keys, unlike grub.cfg's many commands available - BLS format is similar to the GRUB Legacy *conf file format, except no such concept of physical devices or volumes.

Another thing I just thought of: everytime a new kernel is installed it writes to grubenv the saved_entry variable, setting the most recently installed kernel title. That's now the default boot. I'm not really sure of a good work around for that, other than manual intervention. In particular you'd want to disable the hidden grub menu variable in grubenv, so that you have a chance of seeing and changing what will boot. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

It is confusing because there's an upstream bootloaderspec that originated along with gummiboot bootloader which became systemd-boot (or sd-boot). The variants are sd-boot, rpm-ostree, and Fedora's GRUB blscfg.mod and kernel install plugins. Each of these is doing something a little different. sd-boot expects kernel+initramfs+bls *conf files to all be on the EFI system partition. It is a UEFI bootloader only. And it expects to mount the EFI system partition to either /boot or /efi > My understanding, after some reading, is that there has to be a > separate /boot/efi partition, and that was where the BLS information > resided. Out of the box on Fedora 30, whether UEFI or BIOS, the bootloaderspec *conf files (the menu entry drop in scripts) are found in /boot/loader/entries which is a directory on the boot volume mounted at /boot You can optionally not create a /boot mountpoint using custom partitioning, and in that case /boot/loader/entries is a directory on the root volume mounted at / Fedora's GRUB, which includes the blscfg.mod (a GRUB module that parses bootloaderspec *conf files) will find them in either location, regardless of firmware type. So, unlike the upstream bootloaderspec, BLS *conf files are not on the EFI system partition. Pretty much the EFI system partition on Fedora isn't going to be a changing thing anymore. It'll occasionally get some EFI OSLoader (the actual bootloader binaries) updates, and I think fwupd stages firmware updates there for some things (?) that's about it. > But aren't all these BLS scriptlets in the same partition for Fedora? > I thought that under BLS the grub.cfg was just a dummy place holder, > and all the heavy lifting was done by the scriptlets. Depends on your point of view. The grub.cfg speaks GRUB language, and the BLS *conf files are a much simpler restricted set of commands. So most of the GRUB environment setup is still done by grub.cfg, but it's also non-changing. What changes everytime there's a kernel update is the menu entry. That's now in a *conf file, one per kernel. It does very much have the potential to seem like a Choose Your Own Adventure book, because each thing keeps pointing to something else. GRUB pre-boot environment binary -> grub.cfg -> grubenv & blscfg.mod -> /boot/loader/entries/*conf -> /boot/ So the grub.cfg reads grubenv to know things like default kernel, whether last boot succeeded and if so to hide the GRUB menu and if not to show the GRUB menu, and boot parameters. Then grub.cfg executes the blscfg module which in turn reads and parses the BLS snippets. > > Probably, but you would somehow have to convince each OS install to > > update its own part. > > Wouldn't that just be a symbolic link from the /boot(/efi) partiition to > wherever the BLS scriptlets reside? No symlinks on FAT. As complicated as it seems, the way forward for two or more Fedora's is a separate boot volume that's shared among them. And remove the automount of the EFI system partition on the older distro versions. GRUB + blscfg.mod will see /boot/loader/entries contains a bunch of *conf files, one per each distro specific kernel installed. OK I just realized a problem. There is only one grubenv and it will define the root file system as a variable that all of the *conf files will pick up and set as a boot parameter. Option 1: It is possible to change 'options $kernelopts ' by removing $kernelopts and explicitly list the boot parameters you want including a different root. Option 2: It is possible to have two, maybe three, different variables for kernel options in the grubenv, each with a different root; and then just edit the older *conf files to use the proper variable, .e.g. $kernelopts30 or $kernelopts31 Option 3: It is possible to have more than one 'options' key in each *conf file and they are combined So an fc30 conf file: ... options $kernelopts options root=/dev/mapper/fedora-root30 And fc31 conf file ... options $kernelopts options root=/dev/mapper/fedora-root31 That would cause both fc30 and fc31 to boot with the same kernel options in common except for the root which is explicitly set in the *conf file. I haven't tested how the *conf files are created however; I don't know if they are copied, which would preserve the custom defined root, appropriate for that distro version. So this needs testing and a write up if it works. > And I don't have one.

I mean, yeah, you want a separate boot volume if you want grub to have a big picture view of multiple Fedoras; or for that matter any other distro that conforms to bootloaderspec. The reality is the interoperability of bootloaderspec has problems. Similar to GRUB upstream, Fedora's 200+ patches rather makes it like a Fedora specific fork; whereas the bootloaderspec is not exactly implemented by Fedora either. Arguably Fedora's implementation is a superset of the original, because kernel packages detect the use of sd-boot somehow, and will write the bls *conf files to the EFI system volume, which is where sd-boot expects them. Whereas our GRUB blscfg.mod (not upstreamed) will see them most anywhere, I think, which is actually mainly a GRUB feature because it can read files across multiple physical devices. sd-boot does not, and bootloaderspec follows that lineage, where the kernel+initramfs+bootloader *conf files, all exist on the same volume with no way to reference any other volume. > > > So, couldn't there be a utility, which when the user points it at an > > alternate installation, it creates a link in the boot volume with > > priority.

Yes, you can do that in grub.cfg - strictly speaking it should be done with either 40_custom or 41_custom so that if you did regenerate grub.cfg with grub-mkconfig, you'd still get your 'configfile' forwarder in the new grub.cfg instead of stepping on it. > >> Another gotcha is on UEFI, the older Fedora during software updates > >> will (rarely) need to update the bootloader which will step on the > >> binary files in /boot/efi/EFI/fedora, which isn't the end of the world > >> but it's probably better if the old Fedora /etc/fstab is modified to > >> remove the automount of /boot/efi so that the EFI System partition > >> isn't ever updated except by the new Fedora. > > > > For a single large boot directory for all OSs on the system, couldn't > > there be a directory for each OS, allowing for both update and a > > boot selection screen (a menu of available OSs). > > Probably, but you would somehow have to convince each OS install to > update its own part. The EFI system partition location EFI/fedora where we put bootloaders and grub.cfg is basically hardwired. There isn't a way to rename it, e.g. EFI/fedora30 and EFI/fedora31 and keep all the bootloader stuff separate. At least not that I'm aware of - I mean, anything is possible, how invasive that is I have no idea. The advantage of Fedora's variant of bootloader spec is regardless of UEFI or BIOS, the bootloader menu entries are in the same place: /boot/loader/entries which is on the boot volume mounted at /boot. If you do custom installation on UEFI and BIOS to use a directory instead of separate boot, it's still /boot/loader/entries which happens to be on the root volume mounted at / - so it's the same, BIOS or UEFI. This kinda gets us away from the confusion of UEFI's grub.cfg being in a different place than on BIOS (which is still true with BLS feature, but grub.cfg is now a static file that we don't really care about anymore in the typical case; so most conversations about menu entries and boot parameters don't need to be firmware specific until you get suspicious the problem relates to it. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

I think this might have been my error. After reading about UEFI, I see that it needs a separate /boot/efi partition. I have room on the disk at the start before the first /boot partition, but I didn't create that partition during custom configuration. That could have been why it refused to install to the partitions I created as UEFI. Again, I'm struck by how clumsy this all seems. I must be missing something. People wouldn't have invested all the effort they did in these new methods if they didn't solve some problem. ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

What do you mean by it didn't accept them? That's a separate bug report, also needs installer logs attached. Same question. Where are they saved? If the installation is nearly complete, they are probably in /var/log/anaconda on the installed system. Otherwise, they are in /tmp while the installer is running. You can switch to a console to see them or copy them off. Is must be possible to boot a GPT drive from a BIOS mbr because it appears that I was doing that. I can't parse this. The existing F28 on this GPT disk was booting just fine before I tried to install F31. Turn the machine on, and F28 running resulted. Yes, that does work and I see you have the BIOS boot partition. Or, did the hybrid UEFI/BIOS firmware setting allow both? Running 'efibootmgr' will tell you what firmware is being presented to the kernel. # efibootmgr -v EFI variables are not supported on this system (from F28, /dev/sda5, on the GPT drive). So not an EFI boot. The first two partitions are boot, then swap, then two root partitions, then data. The code for the partitions I was trying to install from the iso to are now 8300, the existing Fedora is 0700. That's all suspicious because 0700 for a boot volume isn't correct, and suggests an old version of parted created that partition. Also partition 3 cannot be a root partition, the type code is for swap. That confused me at first as well until I realized he meant there are two /boot partitions like the two root partitions. # fdisk -l /dev/sda Disk /dev/sda: 2.7 TiB, 3000592982016 bytes, 5860533168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 363C9B1D-DBA5-41AE-A74B-6DD5F974ED6D Device StartEndSectors Size Type /dev/sda1 2097152419430320971521G Linux filesystem /dev/sda2 4194304629145520971521G Microsoft basic data /dev/sda3 6291456 48234495 41943040 20G Linux swap /dev/sda448234496 572522495 524288000 250G Linux filesystem /dev/sda5 572522496 1096810495 524288000 250G Microsoft basic data /dev/sda6 1096810496 5860532223 4763721728 2.2T Microsoft basic data /dev/sda72048 6143 40962M BIOS boot Partition table entries are not in disk order.

For the default installation, that hasn't been the case in a long time. One of the reasons this doesn't work out of the box is anaconda doesn't activate LVs for prior Fedora versions, and therefore grub2-mkconfig doesn't discover them. https://bugzilla.redhat.com/show_bug.cgi?id=825236 The bootloaderspec feature in Fedora 30 makes this use case easier to support, but it's still not going to just work out of the box because each Fedora installation has separate boot volumes, which means the latest installed and active bootloader sees only the latest Fedora version's bootloader configuration files. If Fedora versions share a boot volume, then the latest version bootloader sees both installations and can present them in the GRUB menu, but that's not part of the default/automatic installation behavior. One possible gotcha is the boot volume needs to be big enough. For a few releases it's been 1GiB which probably is big enough for two Fedora's to share, because we don't use kdump by default whereas I guess it's configured on RHEL and that was the impetus behind the boot volume size change. Another gotcha is on UEFI, the older Fedora during software updates will (rarely) need to update the bootloader which will step on the binary files in /boot/efi/EFI/fedora, which isn't the end of the world but it's probably better if the old Fedora /etc/fstab is modified to remove the automount of /boot/efi so that the EFI System partition isn't ever updated except by the new Fedora. > I would like the Fedora Installer to be aggressive when it builds its new > boot configuration file, and copy as much as it can from old boot > configuration data.

Something that has been lost is a way to create the bootloader configuration files if they're deleted. With Fedora 29 and older you can just run grub2-mkconfig and that pile of scripts will discover all the information needed to regenerate menu entries. That's no longer the case, as grub2-mkconfig doesn't create menu entries for Fedora anymore, it'll just recreate a static grub.cfg with the command to look in /boot/loader/entries for *conf files. But if those *conf files are missing, you get no entries in the GRUB menu. How do we recreate them? *shrug* Right now that script is in the kernel RPMs, so you'd need to reinstall a kernel to get a new *conf file in place. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

I expect to be able to install Fedora in some disk space, and still be able to boot an older Fedora previously installed in other disk space. I would like the Fedora Installer to be aggressive when it builds its new boot configuration file, and copy as much as it can from old boot configuration data.

That's all suspicious because 0700 for a boot volume isn't correct, and suggests an old version of parted created that partition. Also partition 3 cannot be a root partition, the type code is for swap. > Can I actually somehow do a UEFI install to this disk, preserving the > existing Fedora and being able to boot to it directly? Dual Fedora's isn't officially supported. The installer almost always steps on the previous Fedora's bootloader making it unbootable, in favor of a new bootloader for the new Fedora installation. Sometimes grub2-mkconfig finds the old Fedora and will add entries for it in the grub.cfg, sometimes not. If root is a plain partition, it'll be discovered probably, and if it's LVM, the installer doesn't activate LVM for other installations so os-prober won't see them and won't create menu entries. So you'll have to jerry-rig it yourself after the new installation. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

You can't use the grub config file from the old install, but you might be able to boot it if you add entries pointing to the files there.

I was able to switch the firmware to strictly BIOS from UEFI/BIOS hybrid, with UEFI preferred. That allowed the installer to proceed. Unfortunately, it hung while trying to write an mbr, though everything else worked; it installed software, I was able to set users and passwords. I suspect that is because the disk I was installing to is actually formatted with GPT, since it is larger than 2 TiB. It ran for over 20 minutes at almost 100% CPU and didn't complete. So, I killed it. But it had somehow altered something so that when I tried to boot to the other Fedora installed on that disk, it immediately dropped to a grub prompt.

The lkrn file that downloads the rest of the boot from the net is ~300kB, but that doesn't actually boot the computer, only downloads the next stage. Just a bootstrap. The actual boot first stage is approximately 30 MiB, if my memory is accurate after all this time. I remember it printing several lines of markers to show its progress. That then downloads anaconda for the actual install, and it proceeds just like a netinstall from that point. ___ test mailing list --

But, the hard drives have been in use with older hardware that wasn't. My understanding is that it is difficult and chancy to convert from legacy partitions to GPT partitioning. Is that false? I thought that I had done a direct install for Fedora 21. It was the last time that the BFO option worked for direct install from the net instead of using media. It worked great at that point, but has been non-responsive for several versions of Fedora since, or I would be using it still. But that was a long time ago, so I could be wrong. I have been just replicating the existing Fedora, and then enabling rawhide to upgrade. I suppose I could do that again, but I like a fresh install every so often to get rid of cruft. > Most UEFI firmware today have a "legacy" option or "uefi > enable/disable" option in firmware setup, that will cause a faux-BIOS > to be presented instead of UEFI.

If you boot from the firmware to the Fedora install media in a UEFI-native way, the installer will boot UEFI-native and require you to do a UEFI-native install. If you boot from the firmware to the Fedora install media in a BIOS-native way, the installer will boot BIOS-native and require you to do a BIOS-native install. This isn't something we (Fedora) control, it's between you and your system's firmware. Either you aren't writing your install media and/or booting them quite the same as you did before, or your firmware's configuration has changed somehow from preferring BIOS-native boot to UEFI-native boot. You should be able to find a way to do a BIOS-native boot in the firmware UI somewhere, though. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

That you get GRUB from installation media tells me your computer is presenting itself as having UEFI firmware, because on computers with BIOS firmware the installation media will use isolinux as the bootloader, not GRUB. If the firmware is UEFI, GPT partitioning is required (same as Windows) by the installer. It's been this way since forever, at least Fedora 18. Most UEFI firmware today have a "legacy" option or "uefi enable/disable" option in firmware setup, that will cause a faux-BIOS to be presented instead of UEFI. These days I'm not sure why you'd want to use that, unless you have specific known UEFI firmware bugs that aren't going to be fixed by the manufacturer and also don't have work arounds in either GRUB or the kernel. So I don't really understand why this system has an MBR partitioning scheme in the first place (there are older hardware in the Windows 7 era that were UEFI but shipped with the compatibility support module enabled to present BIOS). Anyway, you need to be looking in firmware setup for this. Probably. I have seen some computers with in-firmware boot manager that shows a USB boot option with a UEFI prefix suggesting they will only boot in UEFI mode from USB if you choose that option; and still another option for the same USB device but without a UEFI prefix (or with a legacy prefix) and that enables the CSM for that boot - it's not a persistent setting. It's kindof a sneaky user interface convention. Off topic: Also, FYI, your mail server configuration asks other mail servers to consider your forwarded emails as suspicious, so gmail users likely don't see your emails at all. I found your post in spam. I don't know for sure the proper way to fix it, but a discussion just happened on devel@ about it. I'm inclined to think this is a Fedora mail server misconfiguration and the poster's mail server's dmarc header should be stripped and replaced with its own (i.e. verify the posted email is valid per dmarc/dkim, then strip that header; and resign the message for the list), but ya whatever.

Thanks for the tip. That enables me to see the problem, but not how to correct it. The boot stanza for the iso uses linuxefi and initrdefi. I can edit the stanza just like a regular boot, but if I try to change those to linux16 or initrd16, the default on my system, they are not found. I tried linux too, just in case it had been made generic, but no go. My experience was that no matter how I tried to bypass the efi boot, I did not succeed. I looked at the rest of the suboptions available, and there wasn't one obvious to my eye that implied an override of the efi boot. Do you have further insight that will enable me to bypass this hurdle? ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

I used custom install with existing partitions on a bios partitioned disk. It refused to install because it wanted gpt and uefi. I swap back and forth between predefined partitions, so I always have a working Fedora to fall back on. This has worked fine in the past. Is gpt and uefi now required for install? I didn't see a way to toggle the setting. If you are booting in UEFI mode, then yes, they are required. If you don't want that, you need to boot in legacy or CSM mode. ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org
