The TS needs help and not a discussion. This thread is full of wrong instructions and advices. To convert disk 1 to GPT and make it bootable is absolutely not the main problem! What do people believe...

Your Diskmanagement Screenshot doesn't allow to give proper advices! Expand columns 1 + 5 so that you can read everything.

Better is to run Command Prompt as admin...

Important: When you are in PE/RE-Mode the drive-letters can change! So don't worry about that!
(D:) is your OS-Partition!
Your Recovery is on (E:) and you boot from there.

We are all happy that you assist us! :p

YES!
And make sure that you saved your settings before you begin. Otherwise you have to do it manually with the data you got from your ISP.

But I don't think that it is possible to convert the disks that way. A 3rd party tool is needed.
Run
C:\Windows\System32>bcdedit

Your Commands are wrong!
C:\Windows\System32>mbr2gpt /validate /disk:0 /allowFullOS
C:\Windows\System32>mbr2gpt /validate /disk:1 /allowFullOS

copy & paste !

PE is when you boot into the Recovery-Mode. (RE) RE is a modified PE.
X:\Windows\system32> indicates that you are in PE

X:\Windows\system32>dir E:\Recovery\WindowsRE /a /s

To get an idea of all your disks run
command prompt as (admin)
and type
C:\Windows\System32>diskpart
list disk
exit

The GPT column is important

Means what?
The first (StartComponentCleanup) or the 2nd Dism-Command (RestoreHealth)?

Tell us what you want. :huh:

Not knowing how to create and upload a "Diskmanagement" screenshot is not a good precondition for a successful Cloning.

Sorry, my mistake! I mean
chkdsk D: /check

You don't have to find any osdevice! It's (D:)
I believe that the Recovery boots from (E:)

Whith a corrupt BCD it would not be possible to to boot...

All that is confusing.
Usually you get a manual with the equipment you buy.
Usually you can save/export the settings and re-import the settings. If not make a photo.

That is wrong! And as long as you are playing you make it worse. When I read TrustedInstaller etc. you ruin everything!
PE doesn't support WiFi and as long as you are working without LAN, you will...

Create a screenshot and add like here:

Boot into Recovery and run
X:\Windows\System32>sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows /offlogfile=D:\sfc.txt

It's better to post a "Diskmanagement" Screenshot showing both disks before you do anything

Only if it's not on (C:) ==> Step 2

It was on C :\Windows\System32\Recovery ! Why did you run Step 2 commands?

You should find these 2 files in the Recovery Folder

Then type...

"... clone ALL the data in both HD's into two seperate files".
Files or Folders ?

Go to the X:> prompt and type:
diskpart
sel disk 0
list par
sel disk 1
list par
exit
bcdedit

If you shrink the size by 1627819 the final C-Partition size will be 279329 MB = 272 GB That is more than enough
So you just click on "Shrink"

I would shrink to 280 GB. That means enter 1620428...

When you unplug the Router you have to wait for ~3 minutes before you plug in again!
