Installer should not format an existing EFI System Partition
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.
I encountered this bug after having the problems in this bug: https:/
