reddragon,

I've not tested it in UEFI mode personally but I understand it supports both BIOS and UEFI installs.

i just tryed systemresucecd, uefi works fine if you disable secureboot.

NeddySeagoon, you dont like uefi? it's all new to me!

I've got the option to just use bios, would that be better?

I was thinking the secureboot and tpm would be good security additions.

reddragon,

My newest hardware is from 2009. It does not have UEFI as an option.
My KVM installs are done by cloning an existing KVM, so they don't count.

The old way is going to go away sometime. If you want to use a HDD > 2TiB you must use a GPT partition table.
Mixing BIOS booting with GPT can be difficult going on impossible with a few BIOSes.

Go with UEFI. Its not that I don't like it, I've not had the the opportunity to evaluate it.

Secureboot can be made to work too.

Why would you trust the keys already in the BIOS and the TPM?
How have they earned your trust or how have you validated them?

I had to resort doing exactly this on my server, which has multiple different sized hard drives. I usually just swap a new one when one starts to go bad. At the moment all but one drive is 2TB in size. Next drive will have more space, unless I get good discount.
Howeve I never managed to set UEFI partition on mdraid1 propely. I used old metadata format and so on (which works with BIOS boot), but the UEFI didn't boot. So I was in luck since my hardware can use BIOS boot and still have all the hard drives with GPT.
I guess on next motherboard/CPU/RAM upgrade I need to put /boot and /boot/efi on some USB stick and call it a day.

Anyway in my opinion the BIOS boot using GPT is the easiest way if the hardware supports it. It should be somewhat easy to test just by creating a bootable usb stick/drive with MBR bootloader and GPT.

Zucca,

You can cheat with MSDOS partition tables on some drives.
The partition table entries are in logical sectors ... some drive advertise 4kB physical and logical sectors.
2^32 4kB sectors is 16TiB.

Setting up an MSDOS partition table to describe up to 16TiB (on suitable hardware) is left as an exercise for the reader.

Heh. Nice cheat indeed.
In fields of computing we always find some interesting way to "artifically respirate" old hardware and software. :)

Fedora has signed releases, so that's what I used to create a LiveUSB.

i used the ubuntu installer. the large image. http://releases.ubuntu.com/16.04.2/ubuntu-16.04.2-desktop-amd64.iso

it has support for uefi, boots in X and fully supports installing gentoo like it's gentoo. so... that worked for me, didn't look for anything else.
