Manjaro dual boot with Kali

Support
1

Hi guys,

I’m running now since some month a setup with manjaro and kali as a dualboot env. It worked pretty well until today after I did an update on kali side. The problem now is, that after I select the manjaro in grub nothing happens, instead I see a “_” on a blackscreen.
After googling around I found a post here with the reference to restore/reinstall grub from the official doc. Sadly nothing changed.

Here is my output, maybe you can see what I did wrong, this from a live-manjaro usbstick:

[manjaro@manjaro ~]$ sudo fdisk -l /dev/sda

switch to sudo and start manjaro-chroot

grub-mkconfig produces an error mabey thats the problem, but I didn’t found anything to fix it.

From what I see Manjaro should be on sdb, what does sudo fdisk -l /dev/sdb return?

3 
fdisk: cannot open /dev/sdb: No such file or directory

right now manjaro is on dev/sda2

4

From the above, it appears to be looking at sdb1.

Two things may be an issue.

  1. sda does not have a a type associated with it, or is the wrong type. It should be Linux you can change it with fdisk -l /dev/sda and then change the device type if its wrong.
  2. The /boot/grub/device.map had sdb1 listed when it should be sda1. Edit the file to the correct drive. The line is (hd0) /dev/sda If the file does not exist, create it with that line.

Run update-grub after trying either.

I didn’t see the sdb, thanks for the hint. Worked! Thanks a lot!!!
