Help installing ubuntu alongside windows?

Solution 1:

1. If you're having trouble getting in to your computer's BIOS setup utility, visit BIOS Setup Utility Access Keys for Popular Computer Systems.

2. If you can't find your computer system in the list, the Del key is frequently used to access the BIOS setup utility. I've also noticed a trend in BIOS/UEFI these days to hide the text instructing you on which key to press, until you press any key.

3. If the BIOS setup utility access key doesn't work, try spamming the key repeatedly as soon as you see the manufacturer's splash screen when the computer is booting.

4. There is a setting in some BIOSs called Fast boot or something like that. It might have toggled off due to low battery causing a reset. This may also explain why the BIOS boot menu is no longer accessible.

5. If your manufacturer's boot screen doesn't show, it wouldn't hurt to change your motherboard's CMOS battery (it looks like a silver coin) and it might help.
