Title:
  Installer should not format an existing EFI System Partition

Status in “partman-efi” package in Ubuntu:
  Fix Released

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.
