I'm trying to do a standard install of Ubuntu 12.4.1 on my computer after accidentally using Pen Drive Linux's USB Installer on my Ubuntu partition. When trying to install i get an error saying unable to unmount /cdrom device busy.
Upon checking Gparted i see that sda5 (what use to be SWAP space before my accident) is mounted to /cdrom and sda5 and 6(ubuntu partition) are both labeled PENDRIVE and sda5 indeed can't be unmounted.
So i tried the command
Code:
sudo umount -l -r -f /cdrom
. No errors were given and upon checking Gparted is is indeed unmounted but i still can't format it to SWAP because the device is still "busy".
Any suggestions?
