I concur. This issue is pretty serious.
Unlike viking777, I used 'Something Else' option during partitioning to
create different partitions, keeping one for installing Mint later.
Little did I know that my Ubuntu install will lock me out of BIOS. Now I
can't get my laptop to boot from the Mint DVD.
My Boot-Repair output is here - http://paste.ubuntu.com/5670796/
I tried the 'shorting' trick to get back the option to let me boot from
CD/DVD, but it didn't work for me. Maybe I missed something.
I do not have anything important in the laptop yet so I am very open to
deleting everything and starting again but I am not sure how to achieve
that since I cannot boot from LiveCD or any other OS. Can I use GParted
to delete the EFI partition? Would I get back to BIOS then?
I hope I do not end up with a dead system - can't reinstall, can't
remove, can't add distros.

Title:
Ubuntu UEFI install locks out UEFI firmware (~bios) access
Status in “grub2” package in Ubuntu:
Confirmed
Bug description:
lsb_release -rd
Description: Ubuntu 12.10
Release: 12.10
apt-cache policy grub-efi-amd64
grub-efi-amd64:
Installed: 2.00-7ubuntu11
Candidate: 2.00-7ubuntu11
Pheonix Secure Core Tiano bios version 1.09
New laptop Fujitsu Lifebook AH532. Windows 7 preinstalled. All
functions worked normally when running Win7. Ubuntu 12.10 installed
using whole disk. Installation successful Ubuntu boots and runs
normally, however all access to the bios has now been lost. Pressing
the default key (f2) during boot up is acknowledged by bios beep, but
ignored and Ubuntu continues booting. In addition the 'boot choices'
menu (f12) contains nothing but Ubuntu making it impossible to boot
from USB or CD/DVD.
The latter (f12) problem was overcome by opening up the machine,
removing the ram and shorting the cl1/cl2 posts with a screwdriver.
This restores the ability to boot from USB/CD by pressing f12 but does
not restore bios access.
The following recovery actions have been tried.
1) Install Boot-Repair, run repair, no change occurred. Boot repair report here:
http://paste.ubuntu.com/1375041/
2) Restore Windows from Clonezilla disk image (factory settings) -
result - bios access is no longer possible from windows either, f2 now
launches the Windows boot menu.
3) Update all drivers using Fujitsu driver update tool from within
windows (which included a bios update). Result - no change, no bios.
4) Restored Ubuntu from Clonezilla disk image - no change.
5) Added second distro to disk. Installed successfully (uefi mode as
that is all I have) no change to bios access.
So overall result I have lost all bios access even from a reinstalled
Windows. I repeat that bios access was perfectly normal before
installing Ubuntu.
I strongly suggest you read the contents of this thread in addition to
