HP UEFI BIOS

  Date: Feb 12    Category: Unix / Linux / Ubuntu    Views: 583
  

My friend got a brand new HP quad core machine with 8 GB of Ram and asked if I
could install Kubuntu on it. "no problem" I confidently replied -
overconfidently, as it turned out.

I didn't know that BIOS's were already shipping with the dreaded UEFI BIOS but
she's got it and it wouldn't even show the first screen from the install disk. I
looked through the BIOS settings and disabled everything that looked like it was
security related. Apparently that disabled it as the install then went smoothly.
One small problem on rebooting: no Grub start menu. It just booted straight into
Win 7.

I put in my Grub Repair disk and it solved the problem, although not as neatly
as usual. It asked me to copy and paste about 4 lines of code into a terminal
window. It said it couldn't install the boot loader in the usual place (MBR) and
recommended it be put on each drive (or partition? Only one 1 TB drive here). I
blindly followed the advice and now on the Grub start menu there are 2 entries
to start Windows, sda1 and sda2. Both work, as does Kubuntu, so I'm not
complaining.

Problem solved and it was a great learning experience. I wish I knew exactly
which BIOS setting disabled the UEFI boot, and whether there was a way to
install a working Grub within Kubuntu. I used the 64 bit Alternate Installer.

So it seems, at this point in time, the HP UEFI BIOS's can still be reconfigured
to permit a Linux install. I'll be very interested to hear the experiences of
others.

UEFI itself shouldn't prevent dual-boot it's the 'Protected Boot', or
'Trusted Boot' section of UEFI that's the problem. Providing the
option to disable it is there then dual-boot is possible but if it has
been permanently locked there's no way to do it, even putting in a
blank HD won't allow Linux to install nor Windows as it happens - the
only thing that will load onto locked systems is the original OS as
supplied with the system. Promises a lot of fun repairing these
systems as it's likely even a Live CD or USB won't run either.

So far as I know there's no hack to get around this but then again
time will tell now UEFI is out and there will be a lot of people busy
trying to crack this one.

If it can be cracked it *will* be cracked, and the results posted for
all to see :-)

As far as I can tell, protected boot was enabled by default, but not
locked, on the machine in question.

This is probably going to be the default from now on so something else
we need to do before dual-booting or even replacing Windows totally.

All the computers that I have bought lately has had the CD boot cut off.
Always had to go into Bio's and set CD to first boot.

 
Answer #5    Answered On: Feb 12    

It's not the boot drive selection that the issue here with Protected
Boot. Also most computers have a key to press during boot to select
the boot drive temporarily, usually [F12] but my own system uses [F11]
and I've seen [F9] used for this. Generally something on-screen during
boot telling you which it expects but it may flash by very quickly.

I know. This is some of M$ bull sh*t, too. I am just waiting for Win 8 to
come out. It will be VERY interesting to see what all
the users do when they find out there isn't an DVD player any more.
But, as for the boot. I am finding more MB makers are setting the HD as the
first boot.

I don't like the direction the industry its going.

In future it might be best to order a bare bone machine (Enclosure/Power
Supply Unit /tested mobo with processor and RAM).
And add an HD + graphics card+ DVD writer yourself ,hence no OS.
The BIOS of such a mobo should NOT have the UEFI stumbling block.

In the UK you now can buy a laptop without an OS.
