Ok, my friend gave me his computer because it wasnt booting up. Me and my dad moved the ram to different slots and it booted but i get a BSOD right after the blue xp caterpillar loading thing. I just wanted to re-install xp pro. Now, the DVD drive doesnt work for whatever reason but i dont care atm. I extracted the .iso and put it on a flash drive, now this particular one was made to boot from a usb drive. When i boot from the drive i get the following error "error loading operating system" and i dont know what to do. Any ideas or guides to install it from the drive?
