I am trying to dual boot ubuntu and windows 10 pro. I have a m2 ssd with windows on it and a normal ssd with ubuntu on it. Both OS work fine.
When I try to boot windows with grub I get this error:
error: no such device: 6E4E-A0AB
error: file `/efi/Microsoft/Boot/bootmgfw.efi' not found
If I then restart my pc and first open the bios and then exit again, I can choose windows in grub and this time I dont get the errors and it boots windows fine. If I then shut my pc down or restart and try to boot in to windows again I get the same error.
I can boot in to Ubuntu just fine no problems with that.
sudo os-prober in ubuntu shows:
dev/nvme0n1p2@/efi/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
sudo update-grub shows:
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'

Can anyone help me resolve my grub problem with windows. Both OS run in uefi mode. I first had Ubuntu installed than disconnected that ssd and than installed windows on the m2 ssd btw. Dont know if that is something.
I would be very thankfull if someone can help me with this.
