This tutorial shows how to prepare a flash drive as a boot drive. This can be useful to install windows on a machine with a broken optical drive.
Run CMD.EXE and type the following. Note: This set of commands assumes that the USB flash drive is addressed as "disk 1". you should double check that by doing a list of the disks (type "list disk") before cleaning it. If you have multiple hard drives, like an SDFlash drive or a Multibay drive, you could end up wiping your second drive using this command.
1. diskpart
2. select disk 1
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit
Now use XCOPY to copy disc contents to your flash drive, if you just use windows explorer it will skip some files.
