My system has three SATA hard drives and an IDE hard drive, so it looks like this:
- SATA 1 - Ubuntu
- SATA 2 - EMPTY
- SATA 3 - Code/Documents
- IDE - Movies/Music
I want to install XP in SATA 2, so I pop in my XP CD and restart. I then try to install in the unpartitioned space:

It comes up with this error on the screen:

To install Windows XP on the partition you selected, Setup must write some startup files to the following disk:
[..]
However, this disk does not contain a Windows XP-compatible partition.
To continue installing Windows XP, return to the partition selection screen and create a Windows XP-compatible partition on the disk above. If there is no free space on the disk, delete an existing partition, and then create a new one.
When I try to create a new partition in the unpartitioned space, I get the same error.
I've tried this on two separate XP CDs with the same results.
