From the OEM
Reinstalling the Operating System on Hewlett-Packard Pavillion Computers.
On some Pavilion computers, registration options may be hidden after a recovery has been performed. The registration screen should appear normally, however the lower options on the agreement form cannot be seen because they are below the screen.
To resolve the issue, use the following steps to continue past this screen and to accept the Windows Millennium licensing agreement:
1. Press and hold the ALT key then press the A key.
2. Press and hold the ALT key then press the C key.
3. Press Enter.
I have no idea if that will deal with the Blue-Patch issue you are facing but it seems to be worth a try.
