New windows 10 installtion on New SSD - wont boot unless old SSD present

It seems you installed Windows while the both SSDs were connected. This would have caused your current problem. Maybe it is sufficient to do this:

1. Launch the Disk Manager.
2. Right-click drive C:, then mark it as "active".
3. Shut down Windows
4. Open the BIOS and tell it that the new SSD is the primary boot device.
5. Disconnect the old SSD.
6. Boot up normally.

If this does not work then you might have to do this:

1. Disconnect the old SSD.
2. Re-install Windows on the new SSD, using the Media Creation Tool.

 

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.

Migrated os to new ssd and it won't boot properly

Hi Dylan_14,

I am Jaspreet Singh an independent advisor.

Have you changed bios settings to boot from the new ssd?

If yes try rebuilding boot record as listed in steps here :

It might be a good choice to check partition layout/format in your new ssd to be sure they are same as Hdd.

** If willing I would recommend a clean install over cloning as newer updates for windows cause a lot issues during cloning that makes it not worth the effort over a clean install.
