My son tried to install a network card on my computer. Now the computer won't boot. I used a boot disk which tries to start Windows 95 but then just gives me an a\ prompt.
I changed to my C\ drive, opened the Windows directory and typed "win". I get an error message that says "HIMEM.SYS is missing. Make sure the file is in your Windows directory."
How can I get my computer to run Windows?
