I have 2 computers, but no Windows DVD

1st Computer is a new one - totally Blank. (Saw an option in BIOS to boot from network.)

2nd Computer is working and has ISO images of Windows XP and Windows7. I would like to install either Windows 7 or XP on the 1st computer. How do I do that? I want to install it via the Network.

Also is there some way to do this through USB?

Both methods are relatively complicated considering you have just an ISO file. Both would require breaking the ISO down, a pre-boot environment, among other things. Burning it to a CD would be much faster & easier. – Garrett Nov 20 '11 at 7:11

There are numerous guides to installing Windows 7 from a USB.
