|Hi kalar. The BIOS settings will be unaffected by any OS issues, reg changes etc. |
When you say that nothing else loads what do you actually mean, i.e. just desktop background image is displayed and nothing else? Can you ctrl+alt+del to load the task manager etc?
Do you remember the key you altered in the reg, and did you may any other changes as well?
If you just want to reinstall but can't see the CD/DVD drive listed in the boot order within the BIOS I'd check the settings under SATA/IDE devices & just make sure all physical connections are tight to the drive as this could easily be why nothings shown/detected.
