im having a very odd issue. my computer does not have an option for cdrom

[rolandroiroi]

@DaBro231 maybe you dont have a cd-rom or your computer system(your motherboard) doesnt recognize your cd-rom because it maybe broken or not properly installed.

I have a few problems...

First my computer does not tell me what button to press to enter BIOS

IT DOES NOT!

Second the closest i came to bios was SYSTEM SETTINGS and i cant get anything done from there..

BTW im using an old Compaq Presario so i can install linux in it.

Help if you can plz
