Re: dual boot installation with UEFI

[Ramiro Aceves <ea1abz%gmail.com@localhost>]

I remember it as a frustrating experience until I figured out how to
boot all the operating systems installed from GRUB.

I remember I finally switched to the UID mechanism cause booting
failed when I forgot an external hard disk connected to the computer
that lead to change in my second drive device.

Regards.
Ramiro.
