So I have a pre-instaled windows 7 EFI boot on SSD in GPT
Ubuntu installer couldn't recongize the SSD so I saw that I should try to zap the gpt using gdisk , before doing that I made a backup to a file of the gpt data.
Now that the SSD has no gpt Windows 7 wont boot at all, so I went back to gdisk to restore the gpt data and I am unable
kubuntu@kubuntu:~$ sudo gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.8
Partition table scan: MBR: protective BSD: not present APM: not
present GPT: not present
Creating new GPT entries.
Command (? for help): r
Recovery/transformation command (? for help): l Enter backup filename
to load: gpt_original
Recovery/transformation command (? for help): w

Aborting write of new partition table.
Note that before deleting gpt I already had the 33 blocks overlap and Windows 7 booted ok. Is there a way to force gdisk to restore my gpt with my backup?
