I found a sata drive, a semi-broken hdd power supply and an esata cable lying around, so I decided to install Arch on it.
So I have sda which has the MBR and grub2 (burg) and then another hdd (below). Burg is installed under Ubuntu 12.10.
The drive is formatted with a GPT. Here is parted's output:
(parted) print
Model: ATA MAXTOR STM316081 (scsi)
Disk /dev/sdd: 160GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 3146kB 2097kB bios_grub
2 3146kB 21,5GB 21,5GB ext4
3 21,5GB 160GB 139GB ext4
grub legacy told me during the Arch install that a 2MB partition (partition 1 above) is required for GPT drives. It doesn't seem to have a filesystem so I can't mount it.
Now I am trying to chainload Arch's grub from grub2 because I could never really get os-prober to work properly with anything.
This is the grub2 menuentry in burg.cfg:
menuentry "Arch Linux (esata hdd, usually /dev/sdd)" --class arch --class os {
insmod ext2
set root='(hd3,2)'
set OS_Boot_config='/boot/grub/grub.cfg'
multiboot /boot/grub/i386-pc/core.img
}
The first problem here is that, as far as grub2 is concerned, (hd3,2) doesn't exist. ls in the grub2 console gives (hd0,msdos1) (hd2) (hd3). In other words, grub2 can't see the partitions on sdd. What can I do about this?
The second problem is that grub legacy claims to have installed core.img to the partition 1 (without a filesystem). I don't know how to mount that, so I am using core.img from the root partition. I have no idea if this is correct, should I change this?
