mbr2gpt crashed, causing an unbootable disk.

tryingmybest · January 30, 2019

I have currently got a new system 16GB of DDR4-2667 MHz memory.

I am planning on using storeMI in order to create a fusion drive whilst still retaining all of my data from my previous machine.

The initial transfer from old machine to my current one was fine... The problem occurred when I was converting my MBR disk to GPT via the command line.

Whilst I was converting the drive I got a BSOD with the error: 'MEMORY MANAGEMENT'.

I can no longer boot (through GRUB) into my drive. Hence the lack of BSOD files present in this post.

Please help as i'm worried I've lost all my data...

Just some extra info:

The memory in UEFI shows up

The pc was acting faster than before today.

Drivers are up to date as the system is brand new.

Thanks in advance.

This is a long shot, I think your boned, but try burning a Plop Boot Manager ISO and try some of the boot options there.

If that doesn't get it.... then... eh... maybe connect the drive to another machine using an adapter and seeing if anything survived.

Seeing as to how it was MBR that means it was legacy boot, so if this doesn't work...

Thanks, I will try this later but I think I may know what the problem might have been.

i think it might have been me using GRUB legacy as it was MBR. Apparently it doesn’t recognise new disks

The problem was, and I think I was lucky, the partition table had been completely zeroed out (the partition locations) and was hence seen as a blank disk. In order to fix that I downloaded the gparted live ISO and booted off of it. I te ran TestDisk from terminal.
