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
It's not a stupid question -- it's an observation of how complexity grows as the number of items grows.
I have found it is better to install mobile racks in each computer, install one OS disk in each computer, and install one OS on each OS disk.
But, if you have fewer computers that OS's, you may find that you are constantly shutting down, swapping disks, and rebooting another OS; only to find that you need the OS you just shutdown. The solution to this problem is virtualization.
