Hi,
I am using a small form factor computer from China. References on the
back of this box :
Wintel Box
Model : w8 pro
I have installed different linux distro but some of them created boot
entries in my UEFI nvram and I can't manage to kick them out.
Command >
efibootmgr
Result >
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0002,0003,2001,0001,2002,2003
Boot0000* EFI USB Device (USB DISK 2.0)
Boot0001* Internal EFI Shell
Boot0002* ubuntu
Boot0003* openSUSE
Boot2001* EFI USB Device
Boot2002* EFI DVD/CDROM
Boot2003* EFI Network
But there no more ubuntu neither openSUSE installed. So I would like to
delete these entries.
Command >
sudo efibootmgr -b 3 -B
Result >
efibootmgr: Could not delete boot variable: No such file or directory
But if I use :
Command >
efibootmgr
Result >
BootCurrent: 0001
Timeout: 0 seconds
No BootOrder is set; firmware will attempt recovery
Boot0000* EFI USB Device (USB DISK 2.0)
Boot0001* Internal EFI Shell
Boot0002* ubuntu
Boot2001* EFI USB Device
Boot2002* EFI DVD/CDROM
Boot2003* EFI Network
The openSUSE entry has disappeared, but the message "No BootOrder is
set; firmware will attempt recovery" means that the old configuration is
restored at the next boot :(
I tried to change the bootorder :
Command >
efibootmgr -O
Result >
efibootmgr: Could not remove entry from BootOrder: No such file or directory
Command >
efibootmgr -o 0000,0001,0002
Result >
efibootmgr: Could not set BootOrder: No such file or directory
Command >
efibootmgr
Result >
BootCurrent: 0001
Timeout: 0 seconds
No BootOrder is set; firmware will attempt recovery

Boot0001* Internal EFI Shell
Boot0002* ubuntu

Boot2003* EFI Network
I don't know if it could be usefull but I tried (without really knowing
what I am doing) :
