Strange Combination of Disk Layouts

Asked by tomdean

I have a strange combination of disk layouts created by keeping disks, etc. See below.

I have an ASUS P9X79 PRO motherboard.

I have two Ubuntu disks and two Windoze disks. I have not used the Windoze installs for several years. Most likely will use these for backup or something.

This came to light when I installed a SDD and started looking to move everything to that. In doing so, I rfe-arranged the physical connection of drives. The new SDD and the two Ubuntu drives are connected to 6GB SATA ports.

In the confusion, I have moved the boot disk away from its lower connection and have to use BIOS boot menu to boot. I guess I need something like 'fdisk /MBR' to fix the boot problem.

Since I have 18.04 for daily use, I plan to put that on the SDD. I think I need 4 partitions.
1. FAT 32 for boot stuff
2. /
3. swap
4. /home - I lost everything one time due to my inability to follow directions when updating...
     With a dedicated /home partition it is more difficult to do that. But, I can find a way!

How do I put a MBR and boot stuff on all the disks?
