Question

The installer needs to commit changes to partition tables, but cannot do so because partitions on the following could not be unmounted. /isodevice

I'm installing this from a external 1TB hard drive there is no internal hard drive ...it crashed so I'm trying to install this via Usb hard drive and i keep getting this error

Ubuntu 11.04 i believe Hp Touch smart tm2 no disk drive

Solution 1

You cannot (easily) install Ubuntu to the drive you are booting from.

The best choice here would be create another installation USB drive with an USB pen or something similar and use that pen to boot installing the system to the USB 1Tb drive.

For more information about how to do so please visit the following links

• Is it possible to install without a Live CD?

Solution 2

simply unmount isodevice

sudo umount -l -r -f /isodevice

and restart the installer
