Install sp1 manually after downloading it - http://www.microsoft.com/downloads/en/details.aspx?familyId=c3202ce6-4056-4059-8a1b-3a9b77cdfdda&hash=hk8tc0PfTIFOyinWnVcGPbw4ZHiQqjbUIOStRi%2b%2f4sb4lN7TqjyQHQJpHWey8i5vfYG5MkTkDDJ65Sf1hWKXeg%3d%3d

As I mentioned in my post there is no C:\ drive to enter into in the command prompt.  Windows is ONLY listed in the X drive.

I assume C as the system drive. So replace C with X and preform the steps.

No, the original system drive is drive C not X.  X might be a temporary drive used in installing the service pack.

Thanks for thei info.  Do you think that if I access the windows directory I can restore windows using the instructions below (links) or is there a better way?

Please read for those of you with the same problem when attempting install of SP1:

The very helpful advice provided by ve3ofa was the missing piece in solving this problem with Windows 7 SP1.

I used the following solution (which worked on two systems with the same type of error):

The solution provided in this EE solution was helpful in solving the issue of not being able to find the C: drive in the Command Prompt as instructed in the link above.  

Running DISKPART "found" the operating system partition which happened to be the D: drive in DISKPART (and became the C: drive again once the system booted back into Windows).

As a side note I did not attempt installation of SP1 after getting back into Windows.

We unleashed SP1 via WSUS yesterday and the **** hit the fan.  b1dupree's 2nd link was the fix for us.

Glad to hear it worked.  

I don't think it matters because there is no alternative in most cases but see this page about editing the pending.xml file--and also read the feedback.
