Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

According to "UbiquitySyslog.txt" the system does not use UEFI. Trying to install grub-efi does not make any sense here. This is not a GRUB issue but an installer problem.

[Steve Langasek (vorlon)]

Heinrich, we always install both EFI and BIOS grub on PCs because of the prevalence of firmware that can be configured to do either, or even present as BIOS when booted from external media but then require EFI for internal disks.
