I have Windows 7 and Ubuntu 11.04 on seperate partitions on my Toshiba laptop. Today when I tried to boot Ubuntu I was met with the error "General error mounting filesystems" and was dropped into a shell. I can't think of anything that I have done since last time I booted Ubuntu that would have caused this. I am relatively new to Linux, so I'm not immediately able to tell what's important information and what isn't.
I booted of a live USB and ran grub-install (something I have done a number of times, when I was shifting partitions around, etc.) but that didn't help at all. In fact grub-install did not detect the bootable partitions on my hard drive like it usually dows, and now all I get is the
grub> prompt. I was able to manually boot into linux, but I got the same error. (If I can boot into Ubuntu, I can run
update-grub but I have to boot into it first; grub is not the real problem).
From my live USB I can mount my Ubuntu partition and work with all the files, but I don't know of anything I can do to try and resolve the issue, or if I should reinstall ubuntu, or if the install process will let me repair the installation or what.
What should I be looking to do? Is reinstalling Ubuntu the easiest option (I assume I can keep my settings and apps?)? I can post more detailed error messages if I know what I'm looking for.
