There's a couple of possible reasons why you got the "unable to lock the disk" error. If you were using a version of Acronis older than 2017 that does not support GPT drives or the person who created your dual boot may have partitioned the drive MBR instead of GPT. I don't know what they actually did so I would suggest you follow the HS or Mojave installation guide on this site and perform a clean installation to the M.2 drive from a Unibeast installer. Of course, you'll need to disconnect the dual boot Windows/macOS drive when doing this. All the info and tools you need are here to do this. Follow the guide for which version of macOS you need. You can create the Unibeast installer on your Macbook or boot from your CCC backup drive and use that.

In step 6 of the installation guide make sure that the partition scheme is GPT. It doesn't specifically say that, but check to make sure that is selected in Disk Utility.
6. For a new installation of macOS, you MUST erase and format the destination drive according to the following steps before continuing.
a. In the top menu bar choose Utilities, and open Disk Utility
b. Highlight your target drive for the Mojave installation in left column.
c. Click Erase button
d. For Name: type Mojave (You can rename it later)
e. For Format: choose Mac OS Extended (Journaled) Scheme: GUID
f. Click Erase
g. Close Disk Utility

Many of the moderators some of the members here do not even boot macOS with a Windows drive connected to their PC at the same time to avoid issues between macOS and Windows. Primarily file and EFI partition corruption and data loss.
Some will use hot swap bays and physically remove the HDD or SSD that the OS is installed upon. The other option is to simply disconnect the the sata cable from the drive you are not booting from before you power on the machine.
If you can't tolerate any down time that is the safest way to dual boot on the same machine. Especially if you use macOS for your work to earn a living.
Thanks for your input. So I'd heard that my issue which was boot would hang on "Start ReadKernelCache" seemed to be memory related, I tried reverting to some older BIOS settings.
Before I’d tried to do this backup task that failed, I was able to boot with igpu enabled, (using the multi monitor enable option in MSI bios) and I’d set the RAM to max which is 64mb only on my system. This had successfully enabled quick sync which I wanted.
However now it won’t let me boot with igpu enabled or maybe 64mb isn’t enough, even though whatevergreen is suppose to fix that and it did not have a problem with this before.
So I’m able to boot with multi monitor disabled.
Just find it odd that I used to be able to boot with igpu on, but now I can’t. I wonder what changed.
Anyway its good enough for now. Thank you.
