My friend's computer has been used and abused. It was a family computer and they had little to no knowledge about basic upkeep for a computer.
One day the system finally crapped out so I said I'd take a look at it. Upon cracking it open everything was caked in dust. It took me a long while to clean it out. Around 4 cans of compressed air later I took his hard drive out and put in my desktop to back up the family files before formatting the drive and attempting to reinstall the os. When I boot the computer I am met with a dialog screen that says choose cd-rom boot type. There is a 1. and a 2. with no descriptions for either. When I press option 1 i get a screen that says press any key to boot from cd which I do because I have a Vista disk in the drive. It takes me to the install screen and I go through the install with no problems. That is until it gets to the point where it needs to restart in order to finish the install. After restarting it gives me the two options again. Pressing 1 again starts the install all over again, pressing 2 give me an os choice but the os fails to start because the install isn't finished. So I am effectively unable to install the os because I don't know what to do after is restarts to finish the install.
His computer is a stock Gateway GT5404 desktop. It had Windows Vista Home Premium 64-bit on it before and I have an extra disk I never used of the same os from which I am trying to do the install.
Any help would be much appreciated.
