I know that you aren't supposed to ask questions about dual booting, but, I've looked everywhere.
My computer is a Dell 3520.
It runs a I3-2120 (maybe) @ 2.1 ghz
4 gb ram
500 gb hard drive.
The bios is UEFI.
I have used ubuntu for a couple of years but all the dual boots I have installed was through the Wubi. I have never used Grub/Grub 2.
I installed Ubuntu from a live disc, and turned on the legacy boot mode but I can not get it to boot into Ubuntu, Windows 8 works fine.
Can anyone give me some advice or direct me to a good tutorial on what Grub is and how to use it? I didn't use Grub, didn't know if I had to, and am not sure how to install it or run it. I really don't want to lose my Win 8 install!
If you are looking for Grub 2 info then I would suggest to refer official site of Ubuntu. Grub 2 info.
Dual booting Win 8 and Ubuntu is almost similar as dual booting Win 7 and Ubuntu and this site has explain dual boot installation quite will with screenshots.
