Hi,
I have latest 21.2.6 xfce Manjaro on the multiboot system with a dozen other linux distributions. My installation and boot is UEFI one. When I boot Manjaro via its own grub - it boots perfectly fine. I can also boot Manjaro via MX Linux grub. But the problem is that my main linux system is Linux mint and I want to use Mint’s grub. And I have problems booting Manjaro with Mint’s grub:/ Booting starts, I select Manjaro from menu and everything stops right away with a kernel panic and message “Unable to mount root fs on unknown-block(0,0)” What am I missing, how can I fix this issue? Thanks.
Thanks for your answers and sorry for not doing extensive search by myself:( Solution in Mint forums has helped. But it strange for me, that update-grub command is not able to generate correct cfg file if it is know issue.
