Hello, This very same issue affected me January 1st 2011.
My setup is: - a laptop with HDA encrypted using SafeBoot (require a SafeBoot MBR to work) - Ubuntu 10.04 LTS 64-bit version on an external USB disk (this becomes HDB/SDB) Selecting using BIOS boot menu whether to boot using internal disk or external disk. (this works very well) On January 1st I received an system update of grub-pc (and other packages), accepted and installed all of them. After the system update it was no longer possible to boot on the internal HD. Discovered that grub-pc update had trashed the MBR of the internal HD. Had to do a SafeBoot MBR recovery (which is a bit cumbersome) to get the system back to normal again. To me grub/grub2/grub-pc is viral, it should not overwrite and destroy the MBR without asking. // Christian -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/495423 Title: update to grub-pc writes MBR without checks, prompt or backup -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
