Missing “C” drive letter

I am working on an old 75 MHz computer running Windows 98 Second Edition.

Don’t know when the “C” drive letter disappeared. Didn’t notice it when I first started working on it.

I installed an external Zip drive that took drive “E”. And I also installed Win98 Plus.

Can’t think of any thing else I did.

“My Computer” does not show “C”, just “A” and CD-ROM drive “D”.

The Windows Explorer is focused on the “C” drive when opened and I can see all folders under “C”. But If I select MY Computer in the Windows Explorer it does not show up.

I have Win98 CD but not the Second Edition so I can’t “repair” and I’m trying not to “fdisk” because I don’t have software for monitor, etc and I really don’t want to take the time since I’m trying to get the computer working well enough to give to a “newbie” which is another reason I would like it looking right so he’ll learn correctly.

Any ideas to get my “C” back?

DA!

I had installed TweakUI and the "C" drive was unchecked.

Thanks
