Hi - I have an HP 520-1138 CB and need to replace the Hard drive. Two questions: what size hard drive do I need to purchase to replace the HD (2.5 inch or 3.5 inch?) and how do I boot the computer up once I install the new HD? I have a recovery disc but how do I reinstall windows?
Ordinarily, I would recommend using HP Recovery Media to restore your PC to its original condition. That would erase the entire drive, format the drive, and install the OS, the drivers, and the HP utilities.
Unfortunately, there is no HP Recovery Media linked to the HP Product Page for your PC. This could be an oversight by HP, or it could also mean that HP no longer stocks the recovery media for your PC.
You can try contacting HP Customer Support directly, using the links below, to see if you can order if from them:
