Ok, A friend of mine had not a clue how to do a reformat on his laptop, so he let me take it home to fix it. I get it home, and find that his problem is that it has the "Windows installer cannot be accessed" error message. After doing some research and following many sets of directions, nothing helps. I am put in the situation that I must reformat. I have tried 2 Dell oem disks that would work for 30 days on it. I was going to use them until he found his actual disks, or he got another XP copy. The Dell oem disks worked on one of my other computers, but won't work on this one. Both disks I have tried say that a file is corrupted. I believe the files changed each time and it is pretty annoying. It won't even let me get to format the computer. I have also tried to boot using a linux cd (which he doesn't want), and it just reverts to hard drive. I then looked in my computer to see if it was listed, but all it showed was the drive and said it was an incompatible disk. Does anyone know what the problem may be? It has 256MB ram, an onboard Graphics controller, and a 1.1GhZ Celeron processor.
