[Bug 1066387] Re: D-I install menu, select Boot from first hard disk and it goes back to Language selection
Also seen in Raring Alpha 1. Today's discussion on #ubuntu-release: infinity menu label ^Boot from first hard disk infinity localboot 0x80 slangasek Boot from first hard disk is done via BIOS calls; if the first hard disk it's booting isn't the one you want, that's a BIOS issue [queuebot] Builds: Edubuntu DVD i386 [Raring Alpha 1] (20121203.1) has been added infinity And yeah, that's just booting 0x80, so if your BIOS is remapping your stick, that's correct. infinity And it's arguably correct for your BIOS to remap your stick when you select it as the boot device. ScottK Hmmm. infinity (Though this behavious varies wildly between machines) slangasek solution: upgrade your firmware to UEFI infinity behaviour, too. slangasek then you can't run syslinux at all, problem solved infinity Hahaha. ScottK So does this option actually do any good? infinity solved. infinity ScottK: It made a lot more sense on CDs, which were never remapped. ScottK Right. infinity ScottK: And it makes sense for people who burn our images to DVDs (same argument). slangasek right, if the issue is that you're booted *from* the USB stick, it should probably detect that and translate it to 0x81 instead infinity That's probably still more common than USB sticks, except for serial reinstallers. ScottK slangasek: That sounds sensible. infinity slangasek: That's a fair chunk of extra magic to ask of syslinux. slangasek IIRC the same el-torito boot image is used for both CD and hybrid USB booting, so this magic would have to be in syslinux slangasek infinity: it doesn't hurt to ask ScottK Also it doesn't have to detect it's a USB, it would have to detect that the device it's about to try to boot from is the same one it's already booted from. infinity But yeah, one could do an if current device = 0x80, shift all menu lookups by 1 or something. I guess. ScottK From the discussion, it seems like that would do it. infinity I'm not sure if it can even reliably know this. infinity Not without more code than it has room to run. infinity Still, yeah, a mildly annoying buglet. ScottK I'll file it and then it will be what it will be. ScottK Turns out there is an existing bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066387 Title: D-I install menu, select Boot from first hard disk and it goes back to Language selection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1066387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1066387] Re: D-I install menu, select Boot from first hard disk and it goes back to Language selection
We could switch to using localboot -1, which calls int 18h, which asks the BIOS politely to try the next boot device. Whether this would have a higher or lower success rate than blindly trying to boot 0x80, I can't say. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066387 Title: D-I install menu, select Boot from first hard disk and it goes back to Language selection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1066387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1066387] Re: D-I install menu, select Boot from first hard disk and it goes back to Language selection
Setting the syslinux status to Invalid for now: currently syslinux is being instructed to localboot 0x80 from the boot menu, which relies on the BIOS actually setting the first (non-syslinux-containing) disk to this address. For folk booting from remapped drives, this fails. Note that there may be a syslinux bug related to this issue, that syslinux may not have sufficient syntax to allow a menu item to express boot from a hard drive other than the one that just booted beyond reliance on BIOS calls (e.g. -1 to send 18h): in such a case, if someone wants to repoen this issue against syslinux to address that, rather than creating a new bug, I encourage them to unset the invalid status. ** Changed in: syslinux (Ubuntu) Status: Triaged = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066387 Title: D-I install menu, select Boot from first hard disk and it goes back to Language selection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1066387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1066387] Re: D-I install menu, select Boot from first hard disk and it goes back to Language selection
The best we can do in syslinux is to boot from whatever it thinks BIOS disk 0x80 is - if your BIOS lies about that and claims it's a USB disk, not much we can do about it. ** Package changed: debian-installer (Ubuntu) = syslinux (Ubuntu) ** Changed in: syslinux (Ubuntu) Importance: Critical = Medium ** Changed in: syslinux (Ubuntu) Status: New = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066387 Title: D-I install menu, select Boot from first hard disk and it goes back to Language selection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1066387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
