I found this guide on how to boot from Linux into Windows without interacing with grub and have followed it but the custom command “wreboot” does nothing and the command it runs “sudo grub-reboot 2 && reboot” when it tries to boot windows from the grub gives me this message. Booting 'windows boot manager (on /dev/sdd1)' error: no such device: 11EA-2C1F. error: disk 'hd3,gpt' not found.
which is the same message grub gave me when i tried to boot windows from it without enabling secure boot in the bios.
EDIT: accidentally left out "Booting ‘windows boot manager (on /dev/sdd1)’ "
the ‘2’ is wrong and it is selecting a device with no bootable efi partition.
you’ll need to count the items inside the advanced options list as well in order to determine the correct numeric designator for your Windows bootloader.
I’m pretty sere it’s 2 i accidentally left out from the error message ’ Booting 'windows boot manager (on /dev/sdd1)’ and following your suggestion and entering 10 just booted Linux as normal
i just launched the first option of advanced options and it launched Linux as normal and the message i get from “sudo grub-reboot 2 && reboot” “no such device: 11EA-2C1F” is the UUID of the EFI partition of the windows drive.
the advanced list itself is not counted - the items inside the list are counted, starting with #2.
for every Linux kernel installed there are 3 items listed inside the advanced options, which makes the next item outside and below this list #5 with only -one- kernel installed.
get it?
with 2 kernels installed there are 6 advanced options listed which would make the next item outside the list #8.
so… count the top item, open the advanced list and continue counting until the last item is counted and then close that list and continue counting to get the numeric designator for your windows bootloader.
I appreciate that you are trying to help but you are clearly wrong entering “sudo grub-reboot 11 && reboot” which by your opinion should launch windows instead launches Linux and the command “sudo grub-reboot 2 && reboot” gives the error " Booting 'windows boot manager (on /dev/sdd1)' error: no such device: 11EA-2C1F. error: disk 'hd3,gpt' not found"
the same error that i would get when i tried launching windows without enabling secure boot the number is correct, it’s trying to launch windows and failing that is the problem not the the wrong number.
nah i have secure boot enabled and if i do it straight from grub or the bios it’s fine but if i launch it with the command sudo grub-reboot 2 && reboot i get the error. Booting 'windows boot manager (on /dev/sdd1)' error: no such device: 11EA-2C1F. error: disk 'hd3,gpt' not found.
