 |
|
So, I have managed to populate my /sys/firmware/efi/efivars by flipping my bios' nx bit back on. I can now see the variables both from the min install environment, outside of chroot, and inside. I then
'modprobe efivarfs'
'mount -o rw,remount /sys/firmware/efi/efivars'
and efibootmanager will show me correctly what my uefi boot entries are. I seem to be having issues getting my changes to stick. In the past, I only had to perform the above steps, less modprobing the efivarfs module to make the changes I wanted to my boot list. I have seen a ton of different examples online, regarding the efivars or efivarfs modules, bind mounting the efivars before, after, or both relative to chroot and have tried a variety of different things. Something has changed since my last usage of efibootmanager and I'm fishing for some suggestions to try next. Thanks.

What command are you issuing exactly?
I had some efibootmgr issues recently, also it didn't lasted for the next login, until I added the -d parameter |

Because my root=/= /dev/sda, I always have to use the -d parameter. That wasn't my issue.
Have found a method that works for my bios, anyway:
I modprobe either 'efivars' or 'efivarfs' before the chroot. After remount my efivars rw, I can then add, and presumably delete entries. I cannot, however change order by doing
'efibootmgr -o'
I must first nuke the order with
'efibootmgr -O'
Only then can I set an order that persist through a reboot.
I'm to the point of kernel panics and other problems which I must sort out now, but it's progres..
