Which ssd has Windows 10 OS...

You were already in diskpart. After you are in diskpart it is "select disk 0", "list part".

Code:

Microsoft Windows [Version 10.0.22621.900]

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> list part

What did you use to perform the clone ?

The usual way to fix these issues is:

1. Fix the os letter of the cloned windows partition
2. Correct the bcd entry using bcdboot

Can be done in a few seconds. In rare cases there has been some file corruption during the copy, but most failures are due to 1 and 2 above. The most reliable program for os migration that I have come across is diskgenius.

I made a little thing that can do 1 and 2 because it is tedious to do manually and I am too lazy to keep explaining all the steps.

Basically what you need to do is

select partition 3
assign letter=Y:
exit
bcdboot D:\Windows /s Y:

Pretty much!

Code:

diskpart
select disk 0
select partition 3
assign letter=y
exit
bcdboot D:\Windows /s Y: /f UEFI
exit

Code:

diskpart
select disk 0
select partition 3
assign letter=y
exit
bcdboot D:\Windows /s Y: /f UEFI
exit
+++++++++++++++

What is the end result of the above?

Thank you.

Thank you.

It should add an os entry pointing at the partition currently showing the letter D to the bcd store on the partition you have just assigned letter Y.

if you were to take a look at the bcd store in Y:\EFI\Microsoft\Boot with bcdedit, the entry would look something like this:

Windows Boot Loader
-------------------
identifier {86429a61-a3b6-11eb-a946-18c04d5e5240}
device partition=D:
path \Windows\system32\winload.efi
description b75-test
locale en-US
inherit {bootloadersettings}
recoverysequence {6cafbce5-5282-11ed-8d61-8396d2e7cd9f}
recoveryenabled Yes
osdevice partition=D:
systemroot \Windows
resumeobject {86429a60-a3b6-11eb-a946-18c04d5e5240}
nx OptIn

If you were to remove the drive letter alias D , then bcdedit will display the device path instead:

Windows Boot Loader
-------------------
identifier {86429a61-a3b6-11eb-a946-18c04d5e5240}
device partition=\Device\HarddiskVolume4
path \Windows\system32\winload.efi
description b75-test
locale en-US
inherit {bootloadersettings}
recoverysequence {6cafbce5-5282-11ed-8d61-8396d2e7cd9f}
recoveryenabled Yes
osdevice partition=\Device\HarddiskVolume4
systemroot \Windows
resumeobject {86429a60-a3b6-11eb-a946-18c04d5e5240}
nx OptIn

In this scenario the letter Y represents the esp partition on disk 0 ( aka \Device\HarddiskVolume3 )
and D represents the windows partition on disk 0 ( aka \Device\HarddiskVolume4 )

That "Y" partition being the EFI System Partition on Disk 0; Volume D: being "WD 2tb ssd".
