Re: Questions on Grub2 and UEFI

What I did was left the /dev/sda (with windows 8.1) untouched.
Installed ubuntu on the /dev/sdb including installing the boot partition
there (/dev/sdb).

Now when I boot my laptop, it loads the disk I've set as the default boot
disk, but if I want to boot the other OS, I press F12 on my laptop where I
can select the boot device.  Then I can choose to boot from sda in windows
or sdb in Ubuntu.

I didn't plan on leaving it that way but it actually turned out to work
pretty well so never bothered changing things!
