Help with Booting

[Mycompsucks]

Okay so the thing is, I have a reallly old computer, the Hp g62 with I got in 2006(estimated). I got a new computer for gaming, so I decided to restore the hp so that I could use it for school and general (youtube, fb, etc.) So when I went into the recovery feature that the Hp bios has (when you start up the computer and you press f11) I tried to do a factory setting restore, but the option was disabled. So, I looked this up on the interwebs and, probably read it wrong, a guide said to change what drive your computer boots up on, which in this case was the d:/ (recovery) drive.
And because of this...well everytime it boots up into the recovery thing, but the option is still disabled.

So my question is, is there a way to change it back to booting with the c:/, where the Os is?

Thanks in Advance.

It's probably all in the BIOS setting you changed... so:
1. You can either undo the setting you changed in the BIOS,
2. You can reset it to default settings; either failproof defaults or optimal defaults.
3. Or you can reset it by removing the battery for at least 5 minutes.. this will delete any user configurations from the BIOS restoring it to factory default settings.
