It's reasonably new and the motherboard has this UEFI thing that
pisses lots of people around. I'm no exception.
I tried to install Debian Wheezy with a USB key, using the 'dd' way
but, even trying different versions of the installer, I always got a
"Insert boot media" message when trying to boot from the USB with (at
least in theory) Debian installer on it.
I have a laptop with Ubuntu installed and could manage to make a USB
startup disk with its own utility (in the same key as I tried to put
Debian on) and it boots OK and even lets me install Ubuntu 12.10 with
no problems and boots in just 15 seconds (it is installed on a SSD drive).
I read about the new Debian 7 installer solving some issues with UEFI
hardware, but I think the problem of not booting the installer relies
on the 'dd way' of setting up the USB key, because Ubuntu's tool at
the end installs a bootloader and a persistent partition if you wish.
Anybody has any tip on how to correctly make a USB install working
(booting, at least) on a UEFI motherboard*? Any issues with the
current installer to take into account with UEFI, partition tables and
Many thanks in advance for your time!
* the motherboard itself is an Asrock Z77 Extreme4-M, with no
possibility of getting a BIOS 'downgrade'.
I'm not sure if dd actually works to produce a bootable USB stick. I
note for example that systemrescuecd doesn't do that. It uses syslinux
to put Linux onto the stick and has another program called install-mbr
to create an MBR.
unetbootin also doesn't just dd something to the key. Have you tried
using it to create a bootable USB stick with your favourite distro?
