I was wondering if you might be able to help me. I picked up a working 4.3GB hard drive on Saturday and tried installing windows 95 and even 98 after that on an older system. I did all the formatting and what not. It is an old AST Advantage Adventure 4050d with a 486/66 system, 4 MB RAM with 32 MB extended, 2x CD-ROM, and it meets all requirements for installing both operating systems. The computer is an all-in-one (monitor built-in to the CPU). I can get Win 95 installed, but it freezes on the first reboot, as does Win 98. I tried step by step confirmation as suggest on Microsoft.com and that doesn't work. When I restart the system again, the entire hard drive erases. I cannot find anything on the internet for this. Maybe you know why this is happening. Is there too much memory for the system? Is there a built-in program on the computer that affects the installation? I have no idea what to do from here. Maybe you can suggest something to try, you would know better than I. I just want to use the computer to screw around with, nothing big. Thank you for your time.
