I had a windows10 and Manjaro on my laptop and everything was Ok.
last day I've installed Kali Linux in another partition. It has installed correctly and it works fine.
But the problem is when I want to boot my Manjaro. I select Manjaro on the grub menu but this is the screen I see.

And this is the Error:




not syncing vfs unable to mount root fs on unknown-block(0 0)




How can I fix the problem?

          VFS: unable to mount root fs on unknown-block(0 0) means the kernel was unable to mount the root filesystem. There are two common causes for this:



          1. The kernel doesn't support the filesystem on the device. If you compiled your own kernel, this is usually because you specified the filesystem driver should be built as a module rather than a native part of the kernel; if you're using the distro's kernel, this is usually because you picked an exotic format for your root filesystem. In either case, don't do that.


          2. The name of the root device passed to the kernel is wrong. This one can be tricky to fix: the best method I've found is to modify the kernel command line from the bootloader, making educated guesses about what the root= parameter should look like until I find something that works.

          • thanks for the responding. but I don't know what to do now. I had Manjaro and everything was ok but after installing Kali the grub screen has changed and when I want to boot Manjaro I get the error. But It is ok for Kali. @Mark

          • kali has messed with your grub.cfg, and now the root= option for manjaro doesn't point to the majjaro root fs. easiest way to fix is to boot kali, list all the partitions (e.g. with lsblk or blkid), write the device names that have a filesystem (e.g. ext4, xfs) except those that you know are used by kali on a notepad and then reboot into grub. edit the manjaro entry and change the root= option on the linux line to one of the partitions. if that partition doesn't work, reboot and try again with another until you find it. when you boot manjaro, run sudo update-grub.

          • if it's not already installed in manjaro, you should install the os-prober packager and run update-grub again. this should allow update-grub to detect the kali partition and create a boot entry for it.
