I create this topic because I find my Windows 10 installation inaccessible, due to an attempt of dualboot set up.
I use Manjaro on in another partition on the same disk.
The MBR is located on the Windows partition, and I still don't understand how it can boot like if everything was okay on Manjaro if the MBR and the partition are messed up.
I can't see the grub menu, Manjaro just boots when (and only) when I configure my bios in Legacy.
I've tried a lot of the time things like grub-update, but nothing more happens.
So, any ideas?
Thank you very much for your help guys.
