Dual Boot Setup: Kubuntu/Ubuntu doesn’t mount Windows’ NTFS Volume when Windows has been hibernated.
I have Kubuntu + Windows XP installed on my machine, and I noticed that Kubuntu sometimes did not load the C: (in windows) or sda2 (in Kubuntu). However, since I rarely needed to access this volume from Kubuntu, I never bothered to look deeply into it. (The volume has been formatted as NTFS, but I think the file system doesn’t matter, it is the drive that had windows installed on it).
It was until recently when I accidentally started Kubuntu in recovery mode, where it showed me the complete log that had something like “Unable to load NTFS Volume sda2, Windows has some entries in the log file, make sure that windows was cleanly shutdown… blah blah blah” (It also mentioned some utility program to run if all else failed, i think its name was ntfs-repair or something).
The actual problem was that I had hibernated Windows and it had written the memory dump to boot drive (C: in my case). So, I just started Windows, and made sure to select “Turn Off” from the shutdown dialog instead of hibernate, and Kubuntu loads the drive fine…
Moral: Don’t expect Kubunbu/Ubuntu to load your windows boot drive if you have hibernated Windows OS.
