Can't Unmount dev/sda3 (boot device)












0















Please help a frustrated user.



I currently run only ubuntu 12.04: I cant seem to umount. I think the umount folder is lost. Tried all possible measures to no avail. Is there a way to force umount. I've been stuck with this umount issues for days now.
I've already applied these but no luck:
sudo umount /dev/sda3
I have equally tried umounting using gparted as well as utility :(

You are advised to unmount them manually" When i used sudo umount /dev/sda3 it said " device is busy.
