Backup any data you want to keep to CD-R.
Set your CD-ROM as the first boot device in the BIOS(press Del,F1,F2,it
depends, usually Del)
Save and exit.
Boot from the Windows XP CD.
Delete all existing partitions. All data will be lost.
Create at least two partitions. One of at least 5GB for the OS, the
remaining space for data.
Format C: aka Partition1, with the NTFS file system.(not quick)
Install Windows XP.
When booted in to Windows XP, you can format the other partition.
