Hi,

I'm having trouble installing Ubuntu on my laptop..

I'm installing from my hard disk using UNetbootin and keep receiving the following error when the installer is attempting to partition the disk:

Failed to unmount partitions

The installer needs to commit changes to partition tables, but cannot do so becaue partitions on the following mount points could not be unmounted:

/cdrom

Please close any applications using these mount points

Would you like the installer to try to unmount these partitions again?

There is an exisiting XP install on the drive, and I have tried various combinations of new partition tables and deleting existing partitions, to be reformated by the installer, to no avail and keep receiving the same error.

Any help welcome!
