I have connected a HDD to my optical drive port and find that Ubuntu can see and mount that HDD. However, I'd like to be able to boot from it. If I do: 'ls' -> shows hd0.. 'insmod ata_pthru'
'insmod ntfs' 'ls' -> shows ata0.. + additional partitions set prefix=(ata0,1)/boot/grub
Problem is the sequence required to boot the Ubuntu or Windows partitions off the shown ataxx partitions. I understand that Windows may need bios INT10/INT13 services to boot, but Ubuntu does not. Can anyone list the command sequence to boot Ubuntu off an ataxx ('insmod ata' or 'insmod ata_pthru') non bios found IDE device?
I have also tried sbootmgr.dsk finding it sees the devices but upon selecting the Ubuntu drive/partition off the optical port, it reboots the system.
