Installing windows after Linux

[Scuzi]

I have a computer here with 2x 120Gb SATA HDDs. I have Ubuntu installed on one and as far as I know the other one is empty.

However, when I open the Disk Usage Analyzer, it shows the "Filesystem capacity" as 212Gb. I haven't set up a RAID array so the two HDD's should be completely separate.

When I browse to "Computer", the drive called "Filesystem" is shown as well as "New Volume" which is unmountable.


Despite all this, I want to install Windows XP on the second HDD which I believe is blank. When I install XP by booting from the CD, how do I get Grub to recognise the installation next time I boot up the computer?

Sorry if this is all a bit noobish!
Thanks

No need to apologise, I have learnt a thing or two from the discussion

Just to be sure, my options are:
1 - Install windows on the second blank drive and after the install, edit the boot.ini to also point to the Linux install.
2 - Remove the Linux drive, install Windows on the blank drive and when it is installed, edit the Grub bootloader to point to Windows.

Is that right?
