Corrupt boot file during Win 10 ISO build

None of the drives are GPT.

You didn't answer my questions:
- You were upgrading to Win 10 Pro from what Win version? Did you run Setup.exe on the USB drive?
- Are you sure that drive 0 is your windows drive? Why it doesn't have a System partition?
- What do you have on drive 2 (149G)?

Boot from a Win 10 installation drive and at the Windows Setup screen, press Shift+F10 simultaneously to open a command line prompt and type:
Diskpart
list vol
exit (to exit diskpart

Is drive 0 a SSD or a HDD?
You have a bigger problem. Partition C: and G: are RAW, they aren't formatted.
You can try to fix it with @jumanji help (don't try to fix by your own) or just do a clean install loosing everything on drive 0.

What do you want to do, try to fix it or do a a clean install loosing everything on drive 0?

For what I can see, drive 2 has a letter E: assigned to it and a label Storage.

Is drive 0 a SSD or a HDD?

@jumanji is the drive expert. He can give you instructions to try to fix the drive.

You can do a Win 11 Clean install.
I suggest you build the USB Win 11 22h2 installation drive using MCT

Reset BIOS or load defaults.
Set Disk mode to AHCI, not RAID
Select OS mode = UEFI
Disable fast boot and secure boot (you can turn it on after installation)

Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
To install as Legacy-MBR you must boot the installation drive as Legacy
To install as UEFI-GPT you must boot the installation drive as UEFI.

As you have a UEFI BIOS, you should install as UEFI-GPT
Detach any other drives (SATA or Power cable) from the MB.

During POST, press F12 to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name) if you want to install as UEFI-GPT or select USB (name) if you want to install as Legacy-MBR.
Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.

Well, it looks like I'll try the clean install to a new ssd and keep the old one to try with @jumanji and see what works best (the most optimal one would have been to be able to restore the C: drive from the macrium backup but I have nothing yet from Macrium on this issue.

That is a very good solution. For now, detach (SATA or power cable if SATA) or uninstall (If NVMe) drive 0.
When doing a Clean install, make sure that the only drive attached is the target drive.

- You boot from the USB Win 11 installation drive as UEFI.
- Go to the install wizard and delete all partitions on the main drive till you have one and only one unallocated space and then proceed.
- It begins to copy all files and then reboot.
- It begins installation
At what phase did you see the message that needed Windows files are missing?

I don't know what's wrong with yours USB Win 11 installation drive. It can be many things, from drive format to missing drivers.
Let MCT create the USB Win 11 installation drive.
