Recently got an old gateway from someone, and the hard drive was fried (why they were giving it away). Found a replacement that came out of another oldie from a friend. It starts up to the boot menu, but says the network is the first boot priority, not the hard drive. I set hard drive to first boot in the bios, but it didn't help. Need advice on what to do now. Do i have to format and re-install Windows (XP)? Just a small tweak in the bios? Maybe somehow boot from a usb drive?
