How to fix "GPT Partition Table is invalid"?

Suddenly, I found out that; my GPT Partition Table is invalid.

I don't exactly know why it happened at this time.

I can boot into first 4 partitions, but not the ones after that (5,6,7)

root@PartedMagic:~# gptsync /dev/sda

Current GPT partition table:
 #      Start LBA      End LBA  Type
 1             40       409639  EFI System (FAT)
 2         409640    464805887  Basic Data
 3      464807936    709003263  Basic Data
 4      709003264    953196543  Mac OS X HFS+
 5      953198592    975953919  Basic Data
 6      975953920    976363519  Basic Data
 7      976363520    976773119  Basic Data
 33   8935142204016934589 1208516115580653323  Unknown
 34   -9223232948424863410 -8868853539174448113  Unknown
 35   6492727242756483169 -3674936763342981582  Unknown
 36   8386109761144168551 8391184066093215337  Unknown

Current MBR partition table:
 # A    Start LBA      End LBA  Type
 1              1       409639  ee  EFI Protective
 2 *       409640    464805887  07  NTFS/HPFS
 3      464807936    709003263  07  NTFS/HPFS
 4      709003264    953196543  af  Mac OS X HFS+
At the end of that that STATUS: GPT Partition Table is invalid.

Those partitions 2 and 3 is NTFS and 5,6, and 7 should be ext4 and there shouldn't be any 33,34,35, and 36. (I can boot into 2,3, and 4 at the moment).

Is there any way that I can fix this?

UPDATE:If anyone encounters the same problem (And who has a bootloader other than the first partition):
The first partition was 200mb FAT32 formatted GPT Protective Partition.
I formatted this partition to FAT32 again.
And then run gptsync.
I did both actions from GParted, but you can use any other tool to format the partition and sync the MBR I guess.

I was so worried because I couldn't boot to partitions over 4 and also; I couldn't even get Clonezilla to see the partitions 3 and 4 to clone them. It just saw 1 and 2.Anyway, in my case, the problem got solved.

Glad to see you fixed it.

Found this article, it might be of some help when more users have GPT disks.
