** Description changed: After upgrading to 12.10 I found that I could no longer boot my system. Instead I ended at a grub rescue prompt. Attempting to fix this by booting from a USB stick built from the 12.04 alternative installer revealed that grub could no longer embed the necessary core.img file. This same configuration worked flawlessly under 12.04, but no longer works under 12.10. This would appear to be a regression. In order to get the system booting again, I had to move to a gpt partition table to allow for the larger core.img size. - - Relevant core.img creation command from attached grub-install debug - output: - - /usr/bin/grub-mkimage -d /usr/lib/grub/i386-pc -O i386-pc - --output=/boot/grub/i386-pc/core.img --prefix=(lvm/ssd-root)/boot/grub - biosdisk ext2 part_gpt lvm - - Resultant core.img size: - - ls -l /boot/grub/i386-pc/core.img - -rw-r--r-- 1 root root 33257 Oct 13 08:45 /boot/grub/i386-pc/core.img ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: grub-pc 2.00-7ubuntu10 ProcVersionSignature: Ubuntu 3.5.0-17.28-generic 3.5.5 Uname: Linux 3.5.0-17-generic x86_64 ApportVersion: 2.6.1-0ubuntu3 Architecture: amd64 Date: Sat Oct 13 08:41:42 2012 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) ProcEnviron: - TERM=xterm - PATH=(custom, no user) - XDG_RUNTIME_DIR=<set> - LANG=en_US.UTF-8 - SHELL=/bin/bash + TERM=xterm + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash SourcePackage: grub2 UpgradeStatus: Upgraded to quantal on 2012-10-12 (0 days ago)
