Windows 10: Cloned M2 SSD will not boot, goes into repair immediatel, Windows 10

I inserted both M.2 SSDs into my PC.
I cloned the main M.2. SSD onto a bigger SSD but keeping the same partition sizes.
The Laptop BIOS can see and IDs both SSDs (one at a time, only one M.2 slot).
The Laptop refuses to boot no matter what, goes into repair mode but no repairs are working.

For some reason the Laptop goes into repair with both old and new M.2 SSD now.

bootrec /RebuildBcd Finds zero installations
bootrec /fixboot says "Access is denied"

I tried to build a USB with the Kyhi ISO and it won't boot even though it sees the Sandisk USB and it looks good otherwise.
Not sure what to do next?

Unable to boot Windows after cloning it to SSD

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while booting the PC after cloning Windows to new SSD. I would like to know what happens when you try to boot the PC to desktop using SSD?



The reason you are not able to boot the PC is that the files required to boot Windows are still recognizing the HDD as the main drive. I would suggest you to try rebuilding the BCD files and see if you are able to boot the PC using
SSD.



Kindly follow the steps below to rebuild the BCD.

1. Create a bootable media and boot the PC using the media.
2. On the Install Windows screen, select Next >
   Repair your computer.
3. On the System Recovery Options screen, select
   Troubleshoot> Advanced options > Command Prompt.
4. Now type in the commands and hit enter: BOOTREC /FIXMBR
   
   BOOTREC /FIXBOOT
   
   BOOTREC /scanos
   
   BOOTREC /rebuildbcd
5. Restart the PC.

If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.

Moving to SSD. Clone or not to clone?

Part of how I keep my SSD fast is to clone it to a platter drive, then clone back. You just want to make sure that you are only cloning teh used space, and not the empty space.


So, again, I isntall Windows to the ssd. Clone to platter drive, then clone back.

I am not sure why, but if I do not do the clone step, the drive's speed, and windows booting, decreases substantially within a week or so.

I am using a Corsair F60 SSD and a Western Digital 500AAKS as drives, and using the free version of Acronis that WD provides, if any of that matters. I am not sure, at this point.

 

2 ssd migration to larger m2 ssd

Hi The

If you can connect both M2's to your system then you can clone the old Ms onto the new one - most systems do not have a second M2 port - you should check to see if that is possible . . .

If you can connect both drives to your system then the free version of Macrium Reflect would be a good choice to perform the cloning . ..

If you cannot connect both drives, then you will be unable to clone the old drive and your only choice will be to backup your data and clean install Windows 10 onto the new M2 SSD
