Noob here. Installed Ubuntu 20.04 to dual boot on my laptop. However, now in grub the Windows Boot Manager doesn't load Windows.

Looking at Gparted, I'm booting from /dev/nvme0n1p1, but the OS is on /dev/nvme0n1p3. Gparted Info

When I select the Windows Boot Manager option, a circle of dots appears, it soon becomes a black screen followed by the GRUB menu again.

I'm not sure why I have 7 partitions - this is what happened after Ubuntu's default installation process.

So far, I've tried boot-repair, updating grub, and changing the default OS In etc/default/grub. Running update-grub finds /dev/nvme0n1p1 as the Windows Boot Manager and displays it, but this drive crashes when launching Windows.

Any help would be appreciated!

    Are you able to go to the UEFI menu and start Windows (successfully) from there?

  • In the UEFI Menu there seems to only be the ubuntu option

  • Run grep -iR -A10 'windows boot manager' /boot/grub.grub.cfg and post up output. May 27, 2020 at 21:47
  • I'm getting no such file or directory

  • Sorry. There should be a forward slash instead of a period between the 2 grubs - ie grep -iR -A10 'windows boot manager' /boot/grub/grub.cfg. May 27, 2020 at 22:58
