I'm trying to recover an HP Pavilion with a Windows 7 looping Startup Repair screen. I download the CD to another computer and Burned a CD. I first changed the boot sequence to start from the CD first. I checked the BIOS and verified the setting. I inserted the CD in the CD ROM Drive of the HP Pavilion and started the computer. The CD does engage and begin to read but then Windows continues to the Startup Repair screen. What next?
