Windows 10: After motherboard upgrade Windows 11 no longer is able to boot from system SSD

I have upgraded computer motherboard and processor.However, after the upgrade the system sees system SSD as not bootable "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart.".Neither previous, nor current motherboard has UEFI, so there is nothing to change here in BIOS.No BIOS settings were changed, including the boot order, which stays the same.Please let me know what I can do here.Reinstalling Windows is really a last resort measure for me, since I will have to reinstall a lot of applications.Thank you.

Thank you for bringing up your query on Microsoft Community.



The only hardware changes that can negatively impact activation status once you upgrade to free version are the changes to the:

The following changes are examples of hardware changes that will NOT impact the activation status:

• HDD/SSD
• Video card

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.

Move Boot Raid-0 to Single SSD

Hello BobBowker,

Thanks for using Microsoft products and posting in the community.

I can help you with your questions on upgrading your boot drive(s) to a new single 1TB SSD. Here are my recommendations:

1. Upgrading the boot drive(s):
   

• a. Create a system image backup on an external HDD: This is a good first step to ensure that you have a backup of your system in case anything goes wrong during the upgrade process.
  
• b. Install new internal SSD (uninstall the M.2s at this point ...?): Yes, you should install the new SSD before uninstalling the M.2 drives. Make sure that you have the necessary tools to open up your computer and install the new SSD properly.
  
• c. Boot to a USB: You will need to create a bootable USB drive with the Windows 11 installation files on it. You can use the Microsoft Media Creation Tool to create this USB drive. Once you have the USB drive, plug it into your computer and boot from it by changing the boot order in your BIOS.
  
• d. Restore system image to the new SSD: Once you have booted from the USB drive, you can then restore the system image backup to the new SSD. Make sure to select the new SSD as the destination for the restore process.
  

1. BIOS settings:
   

• a. Change to UEFI for USB boot to work: Yes, you will need to change your BIOS settings to UEFI mode in order to boot from the USB drive.
  
• b. Confirm UEFI for new SSD boot drive: Yes, you should confirm that the BIOS is set to UEFI mode for the new SSD boot drive.
  
• c. Will other current HDDs still be recognized?: Yes, your other internal HDDs should still be recognized as long as they are properly connected to the motherboard and configured in the BIOS.
  

In terms of using cloning apps to create the new boot disk, it's possible that there may be compatibility issues with the RAID-0 array and the new SSD. That's why I recommend using a system image backup instead.

If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.

I hope this helps! Let me know if you have any further questions.

Please feel free to let me know if you have any further updates, thanks.
