Hi, I have an old (AMD K6-2 350) computer running Windows 98, added a second hard drive some time ago. Recently decided to do new install of Windows, but wanted to keep my original boot drive as is until made sure everything is working, so removed it, left other drive in and made it "single", and installed Windows98 onto it. Installation went fine, booted up and looked OK, so I then made this drive the "master", put my original drive back in and set it to "slave", and computer will NOT boot up, just hangs in the middle of loading Windows. It will boot in Safe mode, have tried MSconfig to disable all startup files, with no luck. I can disconnect the second drive, set the first back to "single", and it still boots up fine. Only thing I see that I'm not sure of, when running fdisk, both drives show to have "active" partition, is this a problem and if so, how do you turn it off (only option in fdisk is to set it on)? Thanks for any help.
