drive mismatch problem

I recently tried to install windows 98 on my studio 1536 on the d drive. the laptop was used and contained no data on the recovery drive so i used it for 98. after booting a floppy dos disk(needed to install 98 for some reason) the pc now fails to boot windows.

i tried to run the repair option from the installation cd and it states that windows vista is installed in the e drive(cd drive) and the e drive has the 320 gb of storage. when the c drive is obviously the real hdd that windows vista is installed on and has 320 gb of storage.

i have never encountered a problem like this before and i can't find a solution searching google. if anyone has any idea how to fix this misreading of the drives please help. I called dell customer support and they wouldn't help me without me giving them the information of whoever registered the computer in the first place.
