I put in a new 80 GB hard drive in the extra slot in my PC. It is the new D drive, formatted and partioned as one large drive. I want to move all files from C to the new drive and install an operating system on D and then switch the drives so that D becomes primary. Do I have to remove the Windows 98 OS from C if it is secondary? And can anyone tell me the order of doing these things really simply. Can I move all my files from C and then swtich the drives in the slots and do a clean install to put the operating system on my D drive? I have just one OS which is Win 98. Thank you.
