Here is my whole situation: I have a dual booted Windows/Ubuntu computer. In order to move from space from the Ubuntu partition onto the Windows partition, I booted into a live Ubuntu 10.10 CD and asked gparted to make my Ubuntu partition about thirty gigabytes smaller, and then move it about thirty gigabytes to the right. Somewhere during the moving operation, gparted gave me an error, and now reports my entire hard drive as unallocated.

On information about the partition, gparted tells me that the first sector is zero, the last sector is xxxxxxx625 and total sectors is xxxxxxxx626. It gives a warning that you cannot have a partition outside the disk.

It also told me, at some point, that I had an invalid partition table.

Output of fdisk -l

I'd like to get my partitions back to working order. I have backups of most of my important data, but it would still be good to locate where my information went. Any help is appreciated.

Edit/Update:

Running test disk to find and restore a partition table, and then running boot-repair, I was able to make the Windows partition bootable and it now works fine. However, gparted still shows the entire disk as unallocated, and I'm incabable of booting into Linux, although I can still look at some files using utilities like TestDisk, and can see the partitions with fdisk. Reccomendations still appreciated
