I was trying to reinstall windows 98 se and got part way through when the computer froze up. I had to do a cold reboot. After the computer finished the POST, a message came on "operating system not installed" (or words to that effect, I'm not at home and am not sure those were the exact words}. Pressing any key just repeated the message. The install did get past the scandisk part and reported the HD as OK. I tried the win 98 boot floopy but the computer just ignored it and came up with the same thing. I can access the BIOS setup but that seems to be all.
