I resized two partitions on the same physical drive and now cannot boot from or mount/read the shrunk partition. I used the Resize wizard and accepted the recommended parameters. The resize proceeded to completion (2hrs) but on rebooting I got a "Kernel panic - not syncing:VFS:unable to mount root FS on unknown block (0,0)". (Ubuntu Linux). PPM can see the partitions and reports their correct sizes as can my Linux rescue CD but cannot mount it. The other, now larger, partition mounts and is readable. I dual boot with XP (on another physical drive) and that still works fine. I have successfully performed this operation (resize) previously but maybe not on my Ubuntu boot partition. Grub comes up as normal. I'm sure all my files are still there but it seems there is some basic address location missing. How can I get it going again?
