Linux and UEFI


Hello all, fresh off a hellish windows 8 - Debian dual boot nightmare and am looking for some insight.

What distro installs well on a UEFI mobo...and by well I mean GRUB can be installed and operate in UEFI?

I've consulted the internet and ran into conflicting information.

Any help is GREATLY appreciated!

Uefi is implimented in differant ways depending on the manufacturer, for example here is a debian install in non uefi mode without a bootloader and then the bootloader added in uefi mode via a live cd of ubuntu or some such. but this only works if you have that bios.

perhaps the best way to get help is to post your specs so those who wish to help can know what they would be installing too, so a distro that may be easiest to install in that situation may be suggested. altenatively if you want to use a particular distro then the system you are using will again help others to know the possible approaches.

hope that helps some

Hi,

I think Manjaro can handle that, they have a WIKI page on thr subject...

Let me know how this works out, that UEFI issue keeps me from getting a new PC...so, any extra info is welcome

By the way: welcome to the forum

I think all distros can now. You just boot the installation medium in UEFI mode. The installer will detect that it was booted in UEFI mode, and do the rest.

I'm currently using Slackware (and elilo instead of grub), booted in UEFI mode. Here's my thread about my experiences. I also know that there were similar threads in the Slackware forum from people who did it first.

So...here's my progress, if you could call it that.

Debian wheezy install = fail
Reason: UEFI boot loader conflict

Debian Jessie install = success
Reason: UEFI boot loader conflict resolved
Stipulations: you must find your windows boot partitions and label them for use in DI.

More to follow... So sleepy

Avoiding the UEFI problem altogether

My impression was the if you buy a laptop with no (meaning no M$ OS) already installed then there won't be a UEFI issue as far as Linux is concerned. Am I correct in this impression?

I'm not sure. If the laptop has windows8 then it has to have UEFI and secure boot. As far a machine with no OS, I don't know.

OK, so with Jessie dual boot I had to launch windows and open up a cmd console and run:

Code:
diskpart
In the disk part console:

Code:
sell disk 0
List partitions
The partition formatted FAT32 is the windows boot partition.

Code:
sel vol 2
My boot partition was number 2.

Code:
assign letter=b
exit
Now I had my boot partition labeled as "b".

I had to do this because the volume size listed after
Code:
 list partitions
was a bit smaller than the volume shown in Debian Installer partition manager, I had to make sure I knew this was the Windows boot partition during the install.

Now once the Debian installer launched the partition manager, I selected "manually manage partitions" and found the partition I had labeled.

I set this as the EFI boot partition and did NOT format it. This simply told GRUB to use this as the primary boot partition.

I formatted the remaining partitions as I normally would.

@ jdk
I think that as soon as the label of the licence is on the thing, it's UEFI, best to go non-branded if possible...or, if you have the time, build one from scratch...
Eh, monday morning here...so, rambling

The link below has some pretty detailed information on uefi in Linux and is fairly current, October 2013.

http://www.rodsbooks.com/linux-uefi/

You can go to the uefi.org site for information also, or google secure boot and uefi and it will be one of the first links as well as a link to microsft and an explanation of Secure Boot/UEFI on windows.
