Computer Stuck in Automatic Repair Loop

but I will check whether or not the standoff was moved while removing the screw.

so have you checked please and what happens if you remove the drive - the samsung, as against uninstalling the driver for it.

Also have you checked the firmware setup to establish if the boot to Windows boot manager has for some reason - been changed, although I suspect at this stage it is an issue with the drive.

Cheers
So does it boot normally if you remove the newly installed drive.

With the drive out - on the advanced options
enter uefi firmware settings
reset to optimized default
save and exit
reboot and try again

Perhaps I should have asked before now - I take it this was a NEW drive, there was nothing installed on the drive and you never installed anything on it after installation of the drive before the problem occurred.

Do you have another computer running 10 and a usb flash pen
If so go to that computer
Download the free Macrium Reflect
Macrium Software | Macrium Reflect Free

where it asks you to insert your email you do not have to do so, it will still download without that
Install the program this other computer.

Then connect your usb flash pen, format it and open the Macrium reflect
click on the GUI - Other tasks and then create rescue media
as per my screenshot

You MAY be thinking - how is that going to work - on my computer with the problem - please trust me - when you boot the computer with the problem from the usb, it will find the installation on that computer albeit it was made on another.

- - - Updated - - -

When you have the computer booted from the rescue media - firstly establish it is seeing the drive with windows 10
the computer will boot to the WindowsPE environment and display the macrium GUI
It will open on the restore tab of the Macrium GUI
Click the backup tab to change to that.
Those are the two tabs below the menu bar
When you click the backup tab - you should then see your drive with the windows 10 installation
Are the partitions on the drive shown eg the system, MSR, Windows and the Recovery - or whatever you know the partitions to have been

You can then make a basic read only check of the partitions by selecting each and the actions arrow will then move to that partition, where you can then click the drop arrow by the side of actions and select "analyse file system"

Presuming that NO obvious errors are seen I then recommend you change to the Restore tab and then select
Fix Windows Boot problems.

Another window will open - Fix Boot Problems - Installed Windows Operating Systems
you then continue from there - as guided on the notes as each window opens.

YOU MAY wish if you have an external drive and you DO NOT already have an image of the existing M2 drive with windows 10 and Macrium PE has found it - to make an image of the drive - all the partitions on it - before you complete the FIX boot solution - to the original problem - if indeed that is a corruption of the BCD on the M2 drive.

1. On the fix boot issues screen did you have the EFI system partition
System partition
The device must contain a system partition. On GPT drives, this is known as the EFI System Partition, or the ESP. This partition is usually stored on the primary hard drive. The device boots to this partition.
The minimum size of this partition is 100 MB, and must be formatted using the FAT32 file format.

2. If so when you configured the repair boot you should have had the option to select the partition from which the boot would be made and it on your windows 10 made from that partition.
Please see my screenshot

3. Yours will not look exactly like that, as this is a 10 and 7 dual boot

4. If you did have the EFI system partition and did not select that then please go back and try that. It will rewrite the bcd
that you now have.

5. See if that changes anything please.
=============================================================================================
6. If that produces no result I recommend most strongly that you use the Macrium to IMAGE that drive to an external hard drive. Image the complete drive - all partitions.
Here is the full user guide to Macrium.

7. Then please go here
https://www.microsoft.com/en-gb/soft...load/windows10

follow procedure for download tool now and the - using tool to create installation media

Follow these steps to create installation media (USB flash drive or DVD) you can use to install a new copy of Windows 10, perform a clean installation, or reinstall Windows 10.

The tool will automatically create the usb for you.
THIS must be made on a Windows computer

8. Then boot from the usb on your computer with the problem
See here and follow option 5 please
Boot to Advanced Startup Options in Windows 10
NOTE
The Reset this PC option in "Troubleshoot" and Startup Settings option in "Advanced options" will not be available using this option.

9. Try a startup repair - three times - as here at point 8
Run Startup Repair in Windows 10
Run Startup Repair again:
Click/tap on Advanced options, and go to step 2 above. Sometimes it may take running Startup Repair up to 3 times and restarting the PC each time to fix the startup issue.


10. If that does not work go to
command prompt
Post back please when at this stage OR when you have some other stage of progress to report.

11. May I stress the importance of imaging the M2 drive before you progress to any attempted repairs, as I mentioned on my previous post and again here, just in case something goes really amiss OR indeed we have to proceed to a clean install.
