Hi, All I want to do is change the boot order of this laptop to CD/DVD first so I can re-install windows as its corrupt and wont boot. I have tried everything to access the BIOS but whatever I try restarts the machine or causes it to beep very loudly. I have tried all of the 'F' keys and the delete key, I have tried holding 0 whilist powering on, I have tried holding (and tapping) escape to stop it from booting windows and then pressing F2, del etc. Nothing I try works and instead it proceeds to try and boot windows and fails. Any ideas?
