Windows 7 to a notebook or laptop that doesn't have a CD-ROM or if you would like to get a speedier install on your desktop PC.
1. Download the latest ISO image of Windows 7
2. Use MagicISO or any other software that can read and extract the contents of the ISO.
3. Extract all the files to a folder of your choice ( ex. C:\Windows 7). If you use MagicISO you would want to right click on the ISO file and then select "Extract to..."
4. attach a USB stick of at least 4 GB size
5. Select "Start->Run..." and type "cmd.exe"
6. At the DOS prompt type " diskpart"
7. type "list disk"
For the rest of this guide I will assume that my USB drive is "Disk 3" and that I've extracted the ISO to e:\
Now, continue to type, in sequence, at the diskpart prompt (without quotation marks):
8. "select disk 3"
9. "clean"
10. "create partition primary"
11. "select partion 1"
12. "active"
13. "format fs=fat32"
14. "assign"
15. "exit"
