Use the UP and DOWN ARROW keys to select an item in the list.

To set up Windows XP on the selected item, press enter.

To create a partition in the unpartitioned space, press C. Windows XP has been installed on the computer so I dont understand that final message. Should I buy an actual Windows XP installation disc? To delete the selected partition, press D.38155 MB Disk 0 at Id 0 bus 0 on atapi [MBR]C: Partition1 [Unknown] 38146 MB Unpartitioned Space 8 MBI choose C: and I hit enter. There are no other options so I press F3 and I get to one final screen: Windows XP has not been installed on this computer. I have a Gateway Laptop Model MX 6121 thats quite a few years old (Im not sure exactly but its definitely more than 7 years old).Recently I have encountered the error screen Unmountable Boot Volume that prevents me from booting my computer.Ive read numerous solutions and the closest Ive come to solving the problem involved downloading a Windows XP ISO and creating a boot disk.I boot from the disk and once the program has finished loading I get a screen that says this: The following list shows the existing partitions and unpartitioned space on this computer.
