[SOLVED] kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)

After upgrading to 10.04 LTS, I get the following error and the computer does not boot. kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0) This is an older laptop, a Dell Inspiron 8600. It’s been running Ubuntu since 8.xx, with periodic updates. The computer boots from a live CD without trouble. The hard drive appears to be completely fine, no problems mounting it while running from the live cd. I set up a chroot on the existing drive, updated the

So all I did to fix the problem was:
– hold down shift while booting so the grub menu shows up
– boot using another kernel (not the first one)
– check if you’re out of disk space on /boot using


Look for the line that ends in “/boot”. Mine said something like this:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1               233191    233191         0 100% /boot

– check which linux images are installed using:

dpkg --get-selections | grep linux-image-

– chech which one you’re using now:

uname -a

– uninstall a bunch of the oldest ones (but leave a few just in case – including the one you used to boot!). You can do this using

sudo apt-get remove linux-image-

then just press tab to get a list of the installed images, type the next digit(s) and press tab again to autocomplete.
– also uninstall the last one (the one that failed) and install it again after all the old ones have been uninstalled)
– before uninstalling make absolutely sure you’re not uninstalling the one you’re currently using! The reason is that you may want to boot again using that kernel, if everything doesn’t work out.
– reboot and see if it works (it did for me).
