I'm now in the process of installing Linux Mint 13 Mate on my PC. I'm attempting to do it both UEFI style (no MBR but GPT with UEFI) and using LVM2 for / and /home from a live USB stick.
After quite a few attempts I managed to get a UEFI bootable life USB stick. I partitioned the SSD to:
/dev/sda1 500M vfat 32 efi partition as /boot/efi
/dev/sda2 500M ext2 as /boot
/dev/sda3 as LVM partition with a VG vol1 and LV /dev/mapper/vol1_root 15G and /dev/mapper/vol1_home 20G
The good news: UEFI works and detects the UEFI live USB and UEFI boot loader and I get to the grub2 menu for the kernels (regular and save mode)
The bad news: Even before the grub menu is displayed, I get an error (which appears to short to really comprehend) and when I select a kernel it goes to a blank screen with blinking keyboard LEDs
I did install LVM2 and grub-efi while chmod to the installed OS. It seems to be a grub problem. Checking the grub.cfg I found an entry at the beginning specifying a UUID that I couldn't see with blkid. I don't know where the hell it got it from. All partitions where mounted, that is /boot/efi, /boot, /, and /home while I ran update-grub and grub-install.
Looking at the grub.cfg it also had the modprobe lvm part, so the LVM partitions (including /) should be OK. The lvm module is also under /boot/...
Somewhere at the Arch Linux site https://wiki.archlinux.org/index.php/GRUB2
they mention to modprobe dm-mod which I didn't load before upgrading and installing grub. I will try it.
So, I've successfully created an UEFI USB live system of Linux Mint 13 RC, but my LVM install doesn't boot yet. I"m optimistic, though. I'm documenting my installation to produce a how-to later on (if I succeed).
Bottom line: I'm now trying to get Linux Mint 13 RC to install on LVM partitions and later on get a Xen kernel with Linux Mint on dom0 and Windows 7 on a domU with VGA passthrough. Ideally the dom0 or Linux Mint 13 would use the Nvidia proprietary driver for my graphic card.
