Since you have an EFI/UEFI system with Windows, you may be able to change boot order with the efibootmgr.

From MX, open terminal and run as root:

Code: Select all

efibootmgr


The boot order of your distros/OSes will be listed, together with a serial number before each OS. For instance,

BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 3002,3000,3001,2001,2002,2003
Boot0000* ubuntu HD(2,c8800,82000,a0d91f49-899b-46ac-8863-35f2d16774c4)File(\EFI\ubuntu\shimx64.efi)
Boot0001* Ubuntu HD(2,c8800,82000,a0d91f49-899b-46ac-8863-35f2d16774c4)File(\EFI\ubuntu\grubx64.efi)RC
Boot0002* Windows Boot Manager HD(2,c8800,82000,a0d91f49-899b-46ac-8863-35f2d16774c4)File(\EFI\Microsoft\Boot\bootmgfw.efi)RC
Boot2001* USB Drive (UEFI) RC
Boot2002* Internal CD/DVD ROM Drive (UEFI) RC
Boot3000* Internal Hard Disk or Solid State Disk RC
Boot3001* Internal Hard Disk or Solid State Disk RC,.... etc etc etc


The above is an example from this link:
https://askubuntu.com/questions/485261/ ... efibootmgr

So let's say your Boot Order is something like:

0001 Windows
0002 MX Linux

The command to change boot order will be :

Code: Select all

sudo efibootmgr -o 0002,0001

or something like that.

You don't need "sudo" if you were already in root terminal.

I got this command from the first answer in the link set out above.

It worked to change my laptop's boot order. I gave a short account of that here: viewtopic.php?p=424211#p424211
Desktop: Intel i5-4460, 16GB RAM, Intel integrated graphics
Clevo N130WU-based Ultrabook: Intel i7-8550U (Kaby Lake R), 16GB RAM, Intel integrated graphics (UEFI)
ASUS X42D laptop: AMD Phenom II, 6GB RAM, Mobility Radeon HD 5400
