Hello,
I'm working on a friends laptop. He asked me to get rid of Win7 on it. He had Xp and another friend thought he'd do him a favor and install 7...on this 2005 Toshiba with .5 GB of RAM, single core processor and 80gb hard drive...it is to laugh. So I am trying to revert it and have had no luck. It was an upgrade install because I see the win.old in the root, and I have salvaged the guys pics, and music, ect...

How do I revert with no disks....either 7 or xp

Since he probably no longer has his disks that came with the machine, and if there isn't an OEM recovery partition, he will need to buy a copy of XP.

There is no true upgrade install from XP to 7, it really is a clean install. See here: http://windows.microsoft.com/en-US/windows7/help/upgrad... Thus, there is no way to "recover" from the install without doing a clean install of XP from a disk or from a recovery partition, which may or may not work to fix this issue.

I borrowed an XP cd and it wont let me run it because there is "a newer version" of windows...arghhh. THe guy's key for a copy is on the bottom of hte laptop. I can't seem to wipe the c: drive or boot he cd....is there a program that can boot and wipe the hard drive before win 7 starts?

You will need to reformat the drive which you may be able to do with a Win7 disk, just stop after deleting the partitions, and then do the OS install from XP. While you are at it I would get rid of all partitions on there -- remember that there will be at least 2, the SRP and the C drive.

As you know, Win does that when it does the initial check to look for Windows installations even if it just an SP1 install and you have an original disk, using the W7 disk to unpartition and then cancelling the install works fine, although there are many other tools that will work.

Not me! I have a DOS 3.1 and 6.2 VM (VMWare 8) to keep me company, I still run some old astronomy and game programs on them, although I have to look at my DOS bible a lot more than I used to.

Hiren's 15 is very helpful, but I don't know if your old laptop will boot off USB.
