[Bug 814412] Re: Grub update renders system unbootable

[Lev Makhlis]

This is also in the attached file, but to make it more obvious, here is
the partition table created by the installer:

$ sudo parted /dev/sda print
Model: ATA Corsair CSSD-F12 (scsi)
Disk /dev/sda: 120GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system     Name  Flags
 1      17.4kB  20.0MB  20.0MB  fat16                 boot
 2      20.0MB  111GB   111GB   ext4
 3      111GB   120GB   8569MB  linux-swap(v1)

Title:
  Grub update renders system unbootable

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Did a clean install of Natty on a new 120G SSD. No dual boot, no
  custom partitions -- I let the installer partition it as it wants. The
  system installed and worked fine until the last grub update, at which
  point it became unbootable ("invalid arch independent ELF magic" +
  rescue shell). grub-install complains, "This GPT partition label has
  no BIOS Boot Partition; embedding won't be possible!"

  After unsuccessfully trying to fix the bootloader, I reinstalled the
  OS from scratch, again with no custom partitions. Again, the freshly
  installed system boots fine, but after the first automatic upgrade
  becomes unbootable.

  Attaching the output of boot_info_script.sh.
