Dear list, I am thinking of a solution of a problem. But I have an understanding problem, maybe you can give some background knowledge.
The problem: I have one harddrive, there are two linuces installed. The partitions are as followed: kali-linux: 1st primary -> /boot 2nd > / debian 3rd primary -> /boot 4th logical > / > swap > /home (encrypted) > /usr (encrypted) > /var (encrypted) This is the structure, and as said before, only ONE drive. Now my question: Is it possible to configure grub that way, that I can choose either kali or debian to boot? What I might to know, please correct me: Both are running different kernels. As far as I understood grub, I can set the root partition ( / ) with the UUID. This is an entry in grub.cfg and maybe in /etc/default/grub. But how can I tell grub, to use the kernel of the second /boot? I dunno, if it is possible at all, to get a dual boot, the way I want it. With a combination of Windows + Linux on one harddrive this is working, however, just because grub does not touch the windows bootloader (as fas as I know), and what of course is also working, if you got two harddrives, each with different linux. They all can be booted from one grub installation, of course. Maybe I could find a solution, if I would have fully understood how grub is working, and what it is doing. Any hints are welcome, and if this does never work at all, please drop me a line. Best regards Hans
