Hi there,
I just fresh installed my system but can't boot it. I have followed the handbook instructions for GPT Grub2 settings but can't see the Grub menu. Instead, I got just a blinking cursor. Well, my mother board is an Intel DX58SO and its BIOS isn't quite old. It has and an option under "Boot" to enable UEFI. However, enable it didn't solve the problem. My partition table is as follows:
Code:
Number  Start   End     Size    File system     Name    Flags
 1      1049kB  3146kB  2097kB                  grub    bios_grub
 2      3146kB  137MB   134MB   ext2            boot
 3      137MB   674MB   537MB   linux-swap(v1)  swap
 4      674MB   106GB   105GB   ext4            rootfs
 5      106GB   2000GB  1895GB  ext4            homefs

and grub2-install worked with no error and grub.cfg goes bellow:
Code:
#

# from /etc/grub.d and settings from /etc/default/grub

Is there anything else I can check?
Any help is appreciated.

When you are booting with UEFI, can you verify with a live cd (booted in UEFI mode) that grub2 is available for booting?
(with efibootmgr)

I found this thread (the first post) useful to get the UEFI/GPT/GRUB2 combination running:

Hi Markus09,
Thanks for your replay. I had have followed this quick guide, but couldn't be able to make things work. So I decided to give up. However, such link can be useful for somebody else.
Best.
