Comment 2 for bug 191844

I've been really kinda' reluctant to mess with KGRUBEditor again; I played around with it when it first became available in the *buntu repos and believe I misconfigured one of the settings, not being familiar with the app. I rebooted my computer and found GRUB couldn't boot to my Kubuntu partition, so I popped in my Alternate CD and did what I've done several times: delete everything in my /boot/grub/* partition and reinstall GRUB. However, it couldn't seem to find either my /root or /home partitions...after some more investigation, I noticed nothing seemed to be able to read the partitions (the utilities I used either labeled their FS type as "unknown" or "linux", and couldn't read the information on them). Thus, I had to wipe everything and start over again (I lost about a weeks worth of data in my /home partition :P). It may have been just a coincidence, such as my partitions happened to become corrupted at the exact time I was using KGRUBEditor, but I've been manually configuring GRUB since then.

I'll give it another try, though, and let you know what I turn up.
