Windows 7: stuck on choose an option test memory

my son brings me his laptop this afternoon not sure exactly what was done but anyway its stuck on test memory, test system and exit. i thought i could go back to factory image but i cant fugure out where its at. any help is really appreciated.

what is the model of your laptop??

its a dell inspiron 1545

how long are you using your laptop?

did you already boot the hdd on you laptop? fix the bios setup

I don't know how.

turn on the power of your laptop and press f2 or del then find the boot sequence then set the hdd on the 1st boot try it

This is what the Setup Guide for your computer says:



That sort of indicates Vista was the original OS for this computer. Is that true? If so restoring to factory state will give you Vista instead of Windows 7.

same thing happens

ive actually tried to do that already to restore factory image. When i press f8 it still loads to choose an option.
