First of all let me Welcome you to PCHF and
apologise profusely for your apparently missed post.
Questions:
This is an
Asrock Conroe 945G...?? (Asrock would be the manufacturer --Conroe the series or model name)
ASRock -> Products -> ConRoe945G-DVI
If I am correct in the first assumption -- have you Installed Windows on this machine yet?? Did it come PRE-installed?
If it is not installed yet you would need to install it.
if it IS installed all you should have to do is reboot/tap whatever key is in your manual to enter the BIOS-setup screens.
When you get there-- you must manually navigate using the arrow keys... to the boot screen/ press enter/ should open boot order dialog -- set the computer to boot from the hd FIRST (highlight 1st boot device/ click enter/ select HD) .
Scroll back up to top, hit F10 should popup "save settings and exit"
Reboot again. should work now-- if not we'll do more checking.
If you do need more help -- plase download and run SIW:
SIW Download
and post the results in your next post so we can be sure we are on the same page for hardware.
