If it is taking you to setup each time you boot then either you made a change in the BIOS while in there that it does not like or there is a hardware issue...
Are both drives still connected ? ?
If so or not have you checked the jumpers and cable positions ? ?

One hard drive = Set as master and hooked to the end of the IDE cable...
2 HDD's            = One set as master cabled as above with the second set as slave and connected to the middle IDE connector...

Note: Some drives have a master/w slave present jumper setting which should be used if there is more than one hard drive connected.
Note #2: Most drives will have a diagram on there label as to how to set the jumpers.

Let us Know.
