I run triple boot with Manjaro Mate, KDE Neon and W10.
All ran swimmingly until there was a problem with a stick of RAM. In the end I had to replace and to cut a long story short, I ended up with a CMOS reset.
The system works fine except that I have to use bootloader from the liveOS to get into the installed Manjaro.
Using GParted, I can see that Manjaro is dev/sdd. When I reboot, Manjaro is shown as sdc3, and it does not boot.
What to do, please? Thanks!
