Due to getting a CODE 5 error when trying to boot from a known good DVD, is there any way I can boot the PC into a DOS type environment and then run setup from the DVD? PC reads the DVD fine but won't boot from it! I tried being crafty by booting from an XP disk, going to the recovery console and then swapping the XP cd for the W7 DVD hoping to go to the dvd and run setup but when I go to the dvd and do a dir command it only shows me a single file named README.TXT ? Reason for all of this is that I have an old PC which I use to test things on. Happily installs Vista BTW.
