I have a triple boot setup on my laptop. Two Linux distros and windows. I started with ubuntu and then added windows afterwards. I then mounted my drive and repaired grub. I setup ubuntu perfectly. Now I am ready to work on windows but all I get is this grey screen when I boot. Does anyone know how to fix this while keeping my ubuntu install?

I think this can happen due to Bitlocker encryption of the drive. What you can try to do if you can get into ubuntu you can try a tool by Daniel Richter called 'grub-customizer'.

sudo add-apt-repository ppa:danielrichter2007/grub-customizer

sudo apt-get update

sudo apt-get install grub-customizer

Once you open the tool, click File -> Install to MBR....

Once you do this, reboot and when you choose your Windows install from the GRUB menu, it should ask you for Bitlocker recovery key instead of grey screen.

Good Luck. M.
