Re: Grub 2: Disk not found error after adding menu entry in 40_custom
I'm not sure if it will solve your issue, but if the Bankix bootloader is installed on the MBR of the card, /dev/sdc, and not on the partition /dev/sdc1, the entry should be like:
set root=(hd2)
Since the bootloader is on the MBR of the disk, you don't specify the partition. If the bootloader is on the partition on the other hand, the (hd2,1) was correct.
Did you check whether grub2 has sdc referenced as hd2? If the card was not present it could have not created a mapping hd2 for it. I think you can make grub2 remake the device map with:
sudo grub-mkdevicemap
Make sure the card is plugged in when you run that.
