partition table was GPT --Quick word of advice: You should get rid
of the previous GPT table by using gparted or gdisk and create a
normal DOS partition table afterwards. You can do this using a live
CD/DVD/USBstick before installing. What happens if you don't
(tried with fresh as-of-this-writing install images for Fedora and
Debian) Is that the partition step will go forward normally and the grub
MBR mambojambo that follows too, but your system wont boot.
I'm guessing you aren't worried about the internals and if you are you
can proly just Google about this and figure out what's going wrong
by yourself (Hint: wrong and dull automagic option selection from the
installer) but in the mean time and if you're in a hurry, just do that ^^
and save yourself some trouble.
There's also a nogpt flag you can pass to the installer at boot time.
Dind't try that one though but guess it should work all the same.
Ah, remember to allow legacy compatibility for non UEFI/GPT
systems on the BIOS boot configuration, option should be available
Tested on a Samsung NP530U3B I had to install Debian on for
my youngest brother. Shit happens.
