* grub-core/kern/emu/hostdisk.c (grub_util_biosdisk_write) [__linux__]:
Fix MBR remapping workaround.
(grub_util_biosdisk_read) [__linux__]: Likewise.
upstream. I attach the patch here as well. Can you confirm?
Is there a build of the applicable patch available in koji (or similar) that I can test against? This fix can be tested with an unofficial scratch build with a snapshot from bzr: grub2-2.0-0.37.beta6.4462.fc17 at http://koji.fedoraproject.org/koji/taskinfo?taskID=4152623 - please test and report back. I can confirm the packages grub2-2.0-0.37.beta6.fc17.x86_64 grub2-tools-2.0-0.37.beta6.fc17.x86_64 Seem to fix the issue here for me. I pulled these from https://admin.fedoraproject.org/updates. I see this listed in bodhi as updates-testing-candidate. When will this be pulled in to updates-testing? Thanks! This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Closing this bug as it was fixed and the fix still works. Thanks for the help! |
Description of problem: Upon trying to boot my Windows partition (I dual boot), I get an error about an "invalid signature". Upon inspection, no root is set for the Windows boot option. When running the grub2-mkinstall, I get the following (clipped for relevance): <pre> ### BEGIN /etc/grub.d/30_os-prober ### No volume groups found Found Windows 7 (loader) on /dev/sda1 menuentry 'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-chain-/dev/sda1' { insmod part_msdos /usr/sbin/grub2-probe: error: unknown filesystem. chainloader +1 } </pre> Notice the <tt>/usr/sbin/grub2-probe: error: unknown filesystem.</tt> error. I think this is the issue. If we look at fdisk, we see the following: Device Boot Start End Blocks Id System /dev/sda1 * 63 401624 200781 7 HPFS/NTFS/exFAT This worked _GREAT_ in F16. If I update my grub2.cfg (for testing!) to include: set root='hd0,msdos1' Things work like I would expect.
