Forcing grub menu to external monitor connected to laptop via HDMI/VGA
Is there any way to force grub menu to show it's content in external monitor (for selecting the os to boot on win or ubuntu), I use my laptop more like a desktop with a monitor connected to it because of broken laptop fan socket. Either HDMI or VGA would work.

Can you set thebiosof the laptop to display on an external monitor ? That should do it forgrubtoo. This is the only real solution I found on Google, but not all laptops have this option.

OK Might of got lucky with this, I assume, because of overheating you would be fine with not having the laptop display on when the desktop boots, right ?

Here is a bad way to do this, for most, that may just be good for you.
On desktop, open this file as root
gksu gedit /etc/default/grub
and find this line
GRUB_CMDLINE_LINUX_DEFAULT=...
and add a this to the end
video=LVDS-1:d
my whole line is
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
so I would add it here
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=LVDS-1:d"
Change lvds-1 for you monitors name, if it is different, find it with
xrandr -q
This will disable the Laptop display for both grub and the desktop and force it to the external display, even if you remove the HDMI cable, the laptop screen will not work. You can remove the change to change it back to using the laptop screen.
I can't test this as I don't have a laptop, but I took it from an question at arch, where the issue was no laptop display after forcing grub to an external monitor.
I don't recommend this for most users who want there laptop to still be portable.

I tried this but it did not work: the menu is not displayed on the external monitor. The external monitor is only activated after Linux has booted.
