Hi all,
I am trying to install 11.10 on a GPT disk, if fails at the software install
and GRUB install step.
Using the alternate installer AMD64 ISO.
Disk layout:
root@ubuntu:/home/ubuntu# gdisk /dev/sda
GPT fdisk (gdisk) version 0.6.14
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): p
Disk /dev/sda: 1465149168 sectors, 698.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 8C5F38B2-BFAB-4A48-8720-5E6BB4434046
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1465149134
Partitions will be aligned on 2048-sector boundaries
Total free space is 1058782 sectors (517.0 MiB)
Number Start (sector) End (sector) Size Code Name
1 2048 411647 200.0 MiB EF00 EFI System
2 675840 677887 1024.0 KiB EF02 BIOS boot partition
3 942080 3039231 1024.0 MiB 0700 Linux/Windows data
4 3303424 1464884942 696.9 GiB 8E00 Linux LVM
Using the 3rd partition as /boot with btrfs.
4th partition as LUKS container with LVM, takes up rest of the disk.
GRUB install fails with cannot find /target/ error.
From what I understand Second stage Grub2 files need to go to EF02 partition(#2 in this case).

Not sure how to do this as Ubuntu installer does not give an option to
choose specific partitions to install Grub.
I am not even sure I got the partition scheme right.
Anyone who's tried this before shed some light on how to setup the
partitions under GPT on a BIOS system.
