Installing 12.2 on Lenovo T420 with UEFI BIOS possible?

Will 12.2 install out of the box on a UEFI setup? Ideally I would just burn the DVD and the installer would take care of the rest (setting up GPT, configuring partitions, etc). Does anybody have any insight on this?

My BIOS is in UEFI mode only. I will not install if I have to resort to using legacy mode.

Yes but do you dual boot? And it may depend on exactly what uEFI you have ie the options. The fact you say you have no legacy mode may or may not raise problems. not because uEFI is not supported but we have no idea how locked down you uEFI is???
It should install no problem but uEFI is a can of worms.

I’ve just tried this on my UEFI-only machine and found that DVD and
NET-CD don’t work. It seems an old bug that was fixed in testing has
become un-fixed. The problem is that the DVD/CD boots using LILO-E
direct into the install section, missing the welcome sign and other
steps. Continuing from there is a waste of time as it only complains
bitterly if you choose to keep Windows partitions and then chooses
GRUB2-EFI for booting. Selecting GRUB2 is no use either as it insists
that’s for testing only and doesn’t work with x86-64.

Now for the good news. Installing via a USB drive went through with no
problems - but you may need to burn it on a 12.1 machine or earlier (using Imagewriter) as burning on 12.2 is hairy.
