Hb_Kai Posted February 23, 2009 Report Share Posted February 23, 2009 When I was using Ubuntu a few minutes ago it suddenly crashed on me and switched itself off.Now each time I try to load the operating system I get this error and it won't load anything after it.[0.832256] kernel panic - not syncing: VFS : Unable to mount root fs on unknown block (0,0)To be honest I've got no idea what this means. I have the idea it might be that the Ubuntu files have gone corrupt somewhere but can't think of anything else.But I have a feeling it's something to do with what I was doing beforehand. I was using the internet and downloading some updates when it logged itself off randomly right when the updates began to install. Got no idea why though. So I logged back on and carried on thinking the updates may just save over each other. Does anyone know what this problem is and if I'm going to have to re install Ubuntu?

andsome Posted February 23, 2009 Report Share Posted February 23, 2009 Have you tried a system restore? Do you have a back up in a program like Acronis? :D Quote Link to comment Share on other sites More sharing options...
-pops- Posted February 23, 2009 Report Share Posted February 23, 2009 I don't know anything specifically about Ubuntu but, don't you have a backup or clone of the drive?Contrary to what some people think, backups are not the exclusive preserve of Microsoft systems. All hard drives are prone to failure - either catastrophic where the drive suddenly dies completely or progressive in which faults gradually develop and which sooner or later become apparent by inconsistency in performance.

Hb_Kai Posted February 23, 2009 Author Report Share Posted February 23, 2009 The only thing close to is there's a copy of each choice on the GRUB boot menu like.Ubuntu, kernel (loads of numbers) -genericUbuntu, kernel (loads of numbers) -generic (recovery mode)Ubuntu, kernel (loads of numbers) -genericUbuntu, kernel (loads of numbers) -generic (recovery mode)Ubuntu, memtestMicrosoft Windows XPSo I have two choices to load Ubuntu. I don't exactly know how but on the second one that says generic at the end, it will load from there and kind of looks like Windows Safe Mode.If I have to use the recovery mode, I don't know much about Ubuntu yet and don't really know how to use it.

Seshomaru Samma Posted February 25, 2009 Report Share Posted February 25, 2009 you got a kernel panicbest way is to choose an older kernel in the grub menu:on the grub menu you have the different kernel versionsthe top one is the latest the second one following is the recovery mode for that kernelthe next one down is an older kernel and so on,,,choose an older kernel in the grub menuoh and take the advice mentioned above - learn how to back up in linuxalso - post in ubuntu forums to solve the kernel panic situation, provide your kernel number and ubuntu version Quote Link to comment Share on other sites More sharing options...
Hb_Kai Posted February 26, 2009 Author Report Share Posted February 26, 2009 I tried using an older one but the problem persisted... So I removed Ubuntu and restarted. :)Cheers anyway, :) And yeah. I will be reading up about linux backups too. Quote Link to comment Share on other sites More sharing options...
scrum Posted March 1, 2009 Report Share Posted March 1, 2009 I tried using an older one but the problem persisted... So I removed Ubuntu and restarted. :)Cheers anyway, :) And yeah. I will be reading up about linux backups too.Booting from an older kernel as found in the GRUB startup menu will usually help.Otherwise boot from a LIVE linux (Ubuntu) CDROM and see what the error is when mounting the ROOT / filesystem.You could also run a fsck (filesystem check) on your harddisk devices....

Hb_Kai Posted March 2, 2009 Author Report Share Posted March 2, 2009 Is that the "Check Disc for Defects" option? I thought that was for the files on the disc... Quote Link to comment Share on other sites More sharing options...
