Help Hard Drive Wipe

Hello, I have nuked my Hard Drive on my old Test Laptop it is a Toshiba Satellite and it ran Windows 7 and out of curiosity I got my old copy of XP to experiment with it and so I got to the wipe stage and completely took everything off the hard drive I have downloaded other copies of XP and put them on USB and those don't seem to work. The CD I used was written in 2002 for a Computer I had built and it ran fine back then, would it be the OS or just how Toshiba built the laptop? When I try to boot from CD (In the BIOS I have it set so the CD/DVD Comes first. Then I press F12 to get to the boot menu and I select CD I have done the same with USB) it says that I need to insert a bootable device. I almost got it working when I used a USB and just threw the files from the ISO In and it said for me to remove anything that doesn't have a bootable OS On it. If there is no fix this is just a test laptop its burnt anyway not worth fixing anymore.

 

Did you just copy the files over to the USB drive or did you use a program to create a bootable drive?

 

Yeah, as iPed22 said: it needs to be bootable, not just the contents of the ISO copied to the USB. Use something like LiLi. it's the one I use, I've only used it for Linux, but AFAIK it works for Windows as well.

EDIT:

Don't use LiLi for it. I would still recommend it for anything else, though. Just search something like: "ISO to bootable".

EDIT: Rufus seem good for the job. BTW I've used it before and it seems good. ALSO:

 

Sorry for the late response I was getting my computer back to seven from ten but eh I will do this later I think but thank you for the responses and I will look into them thank you!
