I have recently encountered an issue when booting from GRUB. As far as I know, I did nothing to spark the issue. :/ I didn't update/upgrade anything and I have had little to no problems with Linux on this machine. I have been running Ubuntu on this laptop for quite a while now and nothing out-of-the-ordinary (like this) ever happened.
The problem: I shut down my computer regularly (by selecting the "shut down" option) and closed the lid (after shutdown was complete). I came back later and turned it on. It started up like normal by taking me to the Toshiba start screen, then it took me to a purple GRUB menu with options:
Ubuntu, with linux 3.22.0-35-generic
Ubuntu, with linux 3.22.0-35-generic recovery
and two other options about memtest. I chose the first thinking nothing was wrong. I waited and nothing happened for about a minute. I restarted it and chose the second option (the recovery). Same result. I restarted the computer, chose the first option, set it down, and started researching the issue on my PC. I came across many articles that didn't really relate to my problem or that i didn't understand. Then, my computer jutted out lines of script. At the end i received this message: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) or something like that. I waited longer but now all that was happening was my caps-lock key was flashing and the terminal-like underscore was continuously flashing as well. (the underscore that appears when it is waiting for a command) I waited over an hour and that is ALL that went on. Please help.
I still do not understand the issue or the steps needed to fix this. I have a minimal knowledge about this and would like things to be explained without expert terminology or with understood steps. In other words, if you would be so kind as to "spell it out" for me, that would be appreciated. All help and efforts are greatly appreciated! Thank you for your time and consideration!
