My windows 10 is installed on m2 ssd (UEFI). Today i have installed ubuntu on separate sata ssd (UEFI). Now i cannot boot windows 10 from boot options list. If i choose m2 from list there is a message Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key Is there a way to boot windows 10? Thanks!

Update the available Operating Systems in the boot configuration:

sudo update-grub

Then reinstall the Boot Loader if it looks correct (you should see windows there):

sudo grub-install /dev/sda

Note that /dev/sda represents the first bootable drive. Re-installing the Windows Boot loader will destroy the Grub boot loader leaving you unable to access Linux.

  • Grub loader was not showing from the beginning. i did sudo update-grub but nothing. Then i reinstalled windows on m2 and now windows boot manage is available in boot list. and Linux is booting by default now. So both windows and linux are working now

  • Usually you would have needed to install the boot loader to the drive in linux because windows doesn't play nice with any other boot loader and destroys anything else on install. Maybe the new windows 10 boot loader handels it now, I'm not sure. Can you clarify this? Sep 17, 2019 at 7:44
