With a pretty red face I am trying to recover my Deepin install.
I had Ubuntu 16.04 installed but wanted to try something different. When I previously removed Ubuntu from my windows dual boot I had to manually remove the ubuntu EFI directory to stop the system launching in the boot menu everytime. Like a moron I tried to do the same with my linux only machine and now everytime I boot I just get:
GNU GRUB version 2.02~berta2-36ubuntu2
I tried just exiting using the exit command but then I just get a message saying install a proper boot device.
I tried to enter failsafe mode from the deepin boot drive to add the efi file back in but I think this is just a live mode so everytime I reboot the ubuntu directory is gone again.
Is there any way to overcome this short of a reinstall? Can I somehow just get the ubuntu efi directory back in there from GRUB or something?
I have now gone through the recovery process as per the comment with Boot-Repair and it still boots in gnu grub.
