Basically, what I’m trying to accomplish here is to familiarize myself with the process (I’m using VirtualBox for that).
FreeDOS – /sda1 (FAT32) [on a PRIMARY partition]
Debian – /sda2 (ext4) [no /boot, no /home in separate partitions, simply “/” on a PRIMARY partition]
Ubuntu – /sda3 (ext4) [no /boot, no /home in separate partitions, simply “/” on a PRIMARY partition]
+ a NTFS partition for system-independent data
GRUB is set to the MBR and able to process the chain (screenshot provided).
Also, as you could notice, I’m not using any SWAP partitions (I’ve got a fairly fast processor accompanied with a plenty of RAM, and even Ubuntu with the default Unity interface idles at ~350 MB in a virtual machine).
Again, I’m simply visualizing the whole process just to make sure I get everything right before I actually slice my hard-drive and risk running into a problem.
I will really appreciate any of your suggestions. Thanks.
