My friend has been using ubuntu 10.10 on vmware player for many days now. But today, it has a problem booting, so we started the ubuntu live cd to try and fix it.
sudo fsck /dev/sda1 (got from No init start up error) says that the
device or resouce busy. So, I'm guessing the partition was not unmounted correctly on the last shutdown for some reason.
Any help on how to fix the problem would be appreciated. If you need any further information, please provide the command to get it, as we have little knowledge of that.
