Hello everyone. As per my post in Thoughts section, I followed in love with Ubuntu MATE, but the software that I'm using for my job, forces me to dual boot it with Windows 10. I used to have Ubuntu 18.04 LTS and after few replies on my topic, I decided to upgrade to 20.04 LTS. When I installed Ubuntu 20.04 LTS 64-Bit on my laptop, when it was about to finish the installation, I received an error when it was installing the GRUB Bootloader.
Powering on my laptop now, boots straight to Ubuntu MATE, without giving me the option to choose if I want to boot to Windows. I think somehow the Windows Boot Manager is messed up and that's why GRUB cannot find it.
I have tried using "sudo os-prober" / "sudo update-grub" / "boot-repair" / "grub-customizer" . None of this allows me to boot back into Windows.
Does anyone know how can I fix the Windows EFI from Ubuntu MATE and how to get it back in GRUB so I can boot into it?
Thank you and Happy Holidays everyone! Wish you all the best.
