By cancelling a GParted partitioning operation, I've lost my OS


Using GParted to try to make a separate partition for /home, I got to the point where GParted put a small "window" on the screen with a bar, moving back and forth, back and forth. It said something like:

Move/Resize

/dev/sda1 to the left and shrink to 40 gig.

after 20 minutes or so of this, I thought the process stuck, so I clicked the cancel button. Gparted shut down fine, but when I tried to reboot from the disk, instead of the LiveCD that gparted ran from (so the drive was unmounted), I find the OS is blown up.

Any ideas?

If gparted never got to the point of writing the new partition table (you would have been given a message to that effect), then it may be possible to resolve this situation.

Can you provide a bit more information (boot error messages, etc) that just

At boot, the typical ubuntu screen comes up a while, then fsck, then more than 10 minutes of words flashing by at the speed of light.

GParted wrote some file, I post it below:

try find a program called 'testdisk' is GPL software runs on Linux and Win32 - it can scan and find you old partition structure and 'hopefully' put it back prior to using Gparted condition. has worked for me when I did the same thing.

PS dont rush partition moving / shrinking etc especially when shrinking ext3 volumes etc

If I could just add a touch more info here, for future reference for the OP:

It is *generally* not recommended to move a partition; particularly the START of a partition. Stretching bigger (to the right) never seems to be an issue, but trouble *can* occur when totally moving a partition.
I suggest instead, when possible, you MAKE a fresh new partition in the area where you otherwise would have MOVED one to, and then COPY the stuff from the old partition TO the new one.
This way, you can be assured you won't bork anything during the move, AND if something IS wrong with the new partition, at least you still have the old one as backup.
When all is proven to be OK, you can delete the old partition.
