invalid main GPT header, valid MBR and corrupt GPT
Posted: 17 Jul 2014, 11:35
I have a W7 machine. I want to partition it so I can dual boot W7 & Ubuntu. I'm on an Ubuntu live disk right now.
I have a thread in the GParted forum http://gparted-forum.surf4.info/viewtop ... 466#p32466, but I arrived at TestDisk because I'm still stuck.
I tried gdisk
So now I've hit a dead end with both "Disks" and GPT. What do you suggest I do?

I tried gdisk
Code: Select all
ubuntu@ubuntu:~$ gdisk /dev/sda5
GPT fdisk (gdisk) version 0.8.8
Problem opening /dev/sda5 for reading! Error is 13.
You must run this program as root or use sudo!
ubuntu@ubuntu:~$ sudo gdisk /dev/sda5
GPT fdisk (gdisk) version 0.8.8
Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!
Caution! After loading partitions, the CRC doesn't check out!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: damaged
Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
1 - MBR
2 - GPT
3 - Create blank GPT
Your answer: 2
Warning! Secondary partition table overlaps the last partition by
16717361815834723826 blocks!
You will need to delete this partition or resize it in another utility.
