[SOLVED] Cloned NvMe Windows 10 BSOD "INACCESSIBLE_BOOT_DEVICE"

[Danifantom]

Hello my friends,
I've spent the last 7 days trying to clone my SATA SSD to my new NvMe SSD in the hours after work.
So my problem is:
My cloned NvMe won't boot, it throws BSOD "INACCESSIBLE_BOOT_DEVICE".
A fresh install works, but I really need it to be cloned for various reasons.

Now, the real thing is, I've tried a lot of possibilities and fixes all over the place.
Things I tried:

• Cloning with various different software
• Cleaning drivers before clone
• Removing peripherals before cloning
• Migrating OS through paid AOMEI partition assistant(I paid U$50 just to do this)
• Cloning by sector
• Repairing boot
• Fixing BCD(this one i tried a lot, manually setting data, copying, repairing)
• BCD doctor
• Various combinations of cloning
• Various combinations of BCD fixing in command prompt, and thrid party software
• Using diskpart to recrate the EFI partition
• Various bootable boot repair software
• The steps in this thread: https://forums.tomshardware.com/thr...zMvSTT02XZsFxh-KeJHyCNYmDjQshCEeb3IgiSreQO_J8
• A couple more things that I don't remember

OK, so my specs are:
Currently working: SATA SSD Sandisk A400 240GB
New NvMe I'm trying to boot into: WD WDS100T2B0C-00PXH0

I have reasons to suspect the problem is in my SATA SSD's system BCD, but I don't have a lot of knowledge in this area obviously. As far as I can tell,
my BCD is a mess, but it works in the old SSD.
I'll be forever in debt ofthe good souls that will(if possible) make this work.
I really need this clone.
I'd rather sell the new NvMe SSD than do a clean windows 10 install.
I have my reasons, but I won't let go of my current install.

When trying to boot after the clone, is this new drive the only one in the system?

Yes it is.
At a couple of cloning tries I got BSOD 0xc00000e but in the majority of the tries it's "INACCESSIBLE_BOOT_DEVICE".
One of the reasons for me to believe it's a BCD problem, is the fact that the currently working SATA SSD has 2 windows boot manager entries, one of them throws BSOD the other one works.

In the new NvMe both throw inaccessible boot device error

Cloning a config that doesn't work quite right just results in a clone that doesn't work quite right.

You need to fix the source first.

Well, the source is booting up right, I'm currently using it right now.
But you're right, I probably need to fix it's BCD, but I'm not quite sure how to.
Tried a couple fixes but none made a difference

PS: I used AOMEI Boot repair tool in source before cloning

Try imaging the SATA SSD to an external hard drive using Acronis, create a portable recovery USB.
install the NVMe and remove the original SATA, boot off the USB - restore from the external.

Since your SSD is a WD you can use their OEM Acronis to do this (dl from their site)
