maybe the card hasn't a bootable partition yet.
open / install gparted,
- Code: Select all
equo install sys-block/gparted
or use fdisk, (both as root)
in gparted, select toggle flags and mark as bootable.
in fdisk, press a, enter the partition number you want to make bootable.
it's a PCI-express SSD card and for sure IS bootable.,
if the card is empty (no partitions yet) you have to make them bootable
