REALLY splitting an SSD

Sep 04, 2026 Last reply: 26 minutes ago 4 Replies

A multi-boot SDD has stolen nine days of my life.



Is there some way of having a split where each part of the SSD has its own MBR etc.



Windows 7-32 and Lubuntu. Probably 99% Windows, if that's relevant.



TIA


If it's NVMe, there are 'namespaces':

It's why it shows up as /dev/nvme0n1 in Linux - that's controller 0, namespace 1. You can create namespace 2, etc. In theory N1 and N2 would appear to the system as different drives.

But it's more of an enterprisey feature and I don't know how well consumer hardware supports it.

I've never used it. Although, funnily enough, I do have a use case similar to yours (KUbuntu and Win11). I might try it sometime, but no promises on timeline.

It is a SATA device.

I save and restore the WIN boot partition every three months. It has worked fine - until it didn't. I'd guess that the back-up / restore (ACRONIS) mechanism has slightly changed the starting sector for the Win

7 restore - but, overridden by GRUB, this completely buggered the booting of Win 7 - leading to GRUB Rescue. BOOTREC did nothing to fix things.

Why now, when this process has worked for five years, I wonder?

Dunno,but Windows 8.1 is my main OS although I can also boot into Windows 10 & Windows 11 (so 3 OS's) on a partitioned M.2 NVMe drive using Easy BCD -

Just install virtualbox on your main system and run the other in a virtual machine

Windows will not acknowledge multiple OS boot loaders
