[Bug 769669] Re: Installer should not format an existing EFI System Partition

[Roderick Smith]

I'm appalled that this bug is still present in the Ubuntu 11.10 beta 2.
ERASING EXISTING OSes' BOOT LOADERS IS NOT ACCEPTABLE!!!!! Since many
(perhaps most) new computers shipping today are UEFI-based, this bug is
rapidly increasing in importance. PLEASE fix it before 11.10 goes final!

Title:
  Installer should not format an existing EFI System Partition

Status in “partman-efi” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: partman-efi

  When selecting an EFI partition under parted during ubiquity install
  on 11.04, there is no option to select mount point.  As windows 7 had
  installed an EFI partition at /dev/sda1 formatted to NTFS, I selected
  that.  I did not select that it should format the mount point, but it
  did anyway to FAT16 and deleted the windows bootloader.  Update-grub
  does not find windows, and I had to go to great lengths to reinstall
  the bootloader to the same partition as windows, it is still missing
  from /dev/sda.

  I had expected that even if /dev/sda1 was formatted, it would at least
  preserve the existing bootloader instead of putting me in a position
  where I had to use a windows recovery disk for several hours until I
  can now at least boot to windows using the bios, but grub is still
  unaware of the windows install.  I expected windows to overwrite grub,
  but I didn't expect installing linux to break my windows install.
