Thank you to all who contributed to this thread and helped me figure out how to run a 2nd DVD Recovery Copy.
I'm guessing both solutions work (deleting hpcd.sys or hpdrcu.prc) depending on the version of Win7 and the model of HP. On my (AMD 64) Pavilion with Win7 Home Premium, I found only the hpdrcu.prc files. However, as Win7 lacks a proper search (Find) feature, some may find it hard to find both files; e.g.
1) If you have partitioned your drive, you may have removed the drive (letter) for the Recovery Partition. As a result, my search with the Everything tool didn't find the file-name on the un-lettered partition. You need to use diskmgmt.msc to Add a Letter for this partition.
2) If you are ultra cautious and chose to rename the *.prc files (instead of deleting them), Win7 does not give you confirmation of successfully renaming them. For peace of mind you can use the DOS Command - CMD in Run - and navigate to the two drives and folders. Using the Attrib *.* command, you'll see both your files renamed, if that was your intention.
Hope this helps a little more.
