Ultimate Boot CD

Alright, first off let me say that I am new to UBCD, but it looks like the best tool I have ever found. The only problem is, it seems to try and read a: instead of c:, making it impossible to do anything with. I cannot do anything on the laptop (Dell) that I am trying to work on. Does anyone know how to change where the programs are looking so I can try and replace the missing ntldr files for this windows machine?

As a final note, in case anyone can help me, I found this tool only after searching for every other possible way to fix this damn error. I cannot even access the partition using a cd loaded copy of ubuntu
