Multibooting

[Torot]

I am looking into setting up a single VM on my proxmox cluster, and within that I want to have a multiboot environment: Say KDE, Fedora, Arch...etc.

Thats not to say it ill only be Linux OSes, I may throw a Windows OS in there for good measure. If your wondering why, I would like to learn how to tweak / adjust / modify the bootloader (like grub, grub2, MS EFI loader...etc).

So, has anyone done anything like this before? I'm picturing it like this:

-create the new host with a large enough disk. -ISO Boot to something like Ventoy (would Ventoy even work)??, or a linux live CD so I can start partitioning the drive as need be. -Reboot and select my first OS of choice and start installing.

I would do this on an old laptop, but if I break something, that is a lot of wasted time trying to get back to baseline, as opposed to just restoring from backup and starting over.

Many thanks.

Basically this should work well. However, I would create a separate virtual drive for each OS, then you won't have to worry about partitioning. I would install Windows first, as this makes working with the bootloader easier.

All other Linux OSs will then write their own entries in Grub, which you can of course modify as you wish. During installation, Linux detects which other systems are already installed. Windows does this too, but it deletes everything right away .

It also makes sense to have a separate virtual drive for /boot. However, I haven't put together an ENV like that yet.
