trikericy,
Unfortunately there are numerous things that can cause this issue, including viruses. Typically pressing F2 when a Dell system is powering on will get you into the BIOS. But you may need to verify that with Dell for your particular model.
If you are able to boot from the reinstallation disk and enter Recovery Console, then you can run the following commands to see if they will help clearing this up.
If the recovery disk provided do not offer the recovery console or those items do not clear it up, then you can perform a factory restore to reload Windows. You will need to check with Dell about the recovery options that they offer. However since you have 2 drives it looks like all your data will be safe and it will just be a matter of reinstalling programs. If you do a factory restore, then I would suggest updating Windows prior to reinstalling the applications.
Hope this helps out.
