How do I remove Windows 7

I'm trying the beta version of Windows 7. It has to be un installed around Aug. I tried to remove it by using an XP pro disc. it can't find the hard drive. I did have Vista Home before I upgraded, but I don't want Vista anymore. Any suggestions?

 

I would use kill disk

When that is done you will be able to install whatever you want.(from disk)

 

Whoa man, you're going in two directions here ATM. XP will not see the Vista/W7 installs as the boot is different. Do you still have XP accessible, or as Bill says, nuke the whole drive? You don't have to do that, not yet anyways. The upgrade bothers me, you'll probably have to get rid of the Vista/W7 install..

 

I had Vista first then wanted to try Windows 7, now I want to put XP on my laptop.

 

OK, very simple. Boot up to the XP CD and choose to format the whole drive or the partition that Vista/W7 resides on, depending on your hard drive configuration. If you do have partitions then everything should still be there after you reload XP.

Oops, missed the laptop part. Was XP pre-installed? Best thing is to restore to factory condition, brand new clean drive.
