A bit more information that may help - I have similar problems to some extent.
For me they came as increasingly bizarre grub.cfg entries such as Colin quoted, and ended with "alloc magic is broken at..." At that point I could not get the list of bootable installs, so not able to boot at all. I booted from a Precise live CD and tried moving grub.cfg files from other places, but no luck. I tried adding a custom_menu cfg file, but the same error showed up and I never got to see the custom menu. Eventually I chrooted into an old Mint 12 install and got it set up as the grub master. I found that running update-grub failed to bring the grub.cfg entries up to date, so had to fix them by hand. All sorts of bad info - kernel versions, UUIDs, had to be edited. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1050774 Title: grub-script-check assert failure: *** glibc detected *** /usr/bin /grub-script-check: double free or corruption (!prev): 0x08210b38 *** To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1050774/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
