Toshiba released 2 updates to my Satellite Windows 10 laptop.
One reset the power settings so that shut down got set back to quick boot and the other changed the order of the UEFI boot so that I could no longer boot into Linux.
Resetting the power options wasn’t a problem but getting Linux back was a little more problematical.
At first I feared that they’d trashed the UEFI boot settings totally so I got a Linux UEFI USB ready to go.
From Windows I took the option to reboot and pick an alternative boot device and restarted.
That was when I found out that things were not as bad as I feared because when I got to the Device selection I had two options:
So I booted into ubuntu and everything was fine.
I searched the internet and found that the efibootmgr command was what I needed to use … and this is what it showed me:
As you can see the Timeout is set to 0 but the boot order has been changed so that 0002 (Windows) is the first option.
So I did the following:
efibootmgr -o 0001,0002,2001
and then checked the boot menu again:
I then rebooted and everything worked perfectly.
So if you’ve lost your boot menu then you might be able to get it back extremely easily….
