The key to go into the bio's is normally.
"F2" Or "Delete" in some case's.
If your computer loads ungodly fast.
>:3
Push that button non stop.
xD
Then when you are in the bio's depending on the set up you are looking for something that will change how your hard drive is being read.
Or in general looking for the key words.
"IDE" - "AHCI" as kinda a pointer.
"Sata" is one to look for also.
