Can I change drive numbers from within windows 10?

The WinRE.wim probably got lost.
But thats not an disaster. We fix it.

But I need the result of this

reg query HKLM\SYSTEM\CurrentControlSet\Control /v FirmwareBootDevice
reg query HKLM\SYSTEM\CurrentControlSet\Control /v SystemBootDevice

It shows if the old EFI on Disk 1 can be deleted without risk or not

If I do a search for the file on drive c; in explorer I don't find it?


C:\WINDOWS\system32>reg query HKLM\SYSTEM\CurrentControlSet\Control /v FirmwareBootDevice

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
FirmwareBootDevice REG_SZ multi(0)disk(0)rdisk(0)partition(1)


C:\WINDOWS\system32>reg query HKLM\SYSTEM\CurrentControlSet\Control /v SystemBootDevice

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
SystemBootDevice REG_SZ multi(0)disk(0)rdisk(1)partition(2)


C:\WINDOWS\system32>

You can try, but it can take a long time. Therefore I used the dir-command that searches only in Windows\System32

I did it but it found nothing.

Is the file just a common file on all windows 10 machines? I have another windows 10 machine , I could copy it from there?

Yes, it's possible Good Idea.
But we do it later, because we can check first if it has been updated to Build 3920 or not

But you only find it there in C:\Windows\System32\Recovery when you execute reagentc /disable first

OK have we done that successfully ? might it be an idea to do it again?

OK
we also can delete the old EFI on disk 1.

No it was not on R:

But your idea to copy it from a different machine is good.

But let me create a detailed plan first how we design the new disk 1.
Here it is very very late and I need a bed.
I prepare a solution and will be back tomorrow
Good night

OK thank you for your time have a good day tomorrow.

C:\Windows\System32>
diskpart
sel disk 1
sel par 5
set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
gpt attributes=0x0000000000000000
delete partition overide
sel par 4
set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
gpt attributes=0x0000000000000000
delete partition overide
exit

Now you have to decide if you want a bigger C-Partition
1) 134 GB+ 102 GB + 512 MB ~237 GB
or a second Data-Partition (E:)
2) 102 GB + 512 MB ~103 GB

When that is clear we solve the WinRE.wim problem

Good evening Sir,
I have done all that and see no errors.
It still fails to allow me to insert an image so I have added the management update as an attachment.
I can't find the winRE.wim file on the other computer.

But you only find it there in C:\Windows\System32\Recovery when you execute reagentc /disable first

maybe reagentc hasn't been executed on there.
I am happy with just the one partition.
Did I say I contacted the person who made up the computer for me and he said, much to my surprise, that it has two physical drives.
