Windows 10: Windows 10 will not boot after partition merge.

I used Aomei Partition Assistant to merge an unallocated partition with the main OS partition and now Windows will not boot. I get the following error: "No bootable devices found."I tried using a bootable USB drive to access the troubleshooting advanced options but no luck. Startup Repair could not fix the problem. I was unable to use System Restore or System Image recovery. How can I correct this?

:)

 

Is it possible to merge the OS partition and the boot partition?

I have 4 partitions on my HDD and am unable to download some diagnostic software due to this. I have a 500 MB reserved, OS, boot and recovery partitions. Is it possible to merge any of these partitions to make one available in Windows 10 education version?

 

How to merge the Health (Recovery Partition) in Windows 10

Previously, I used AOMEI Partition Assistant without any issue, but now after I delete the 450 MB Health (Recovery Partition) & merge with my C: drive, this error popped out; (I'm unable to merge it anymore)

"The version of your system is equal or higher than 1703. We suggest you don't resize/move system partition, which may cause system boot failure. We suggest create a Windows PE bootable media and rezise/move system partition with it."

Any suggestion to merge the partition? Thanks & greatly appreciated. FYI, I tried various application also not working.

There's a \\?\Volume{ff855cc7-980a-44a3-aa46-1eed8d8c8b8c}\ located on Optimize Drives.

Recovery partitions after the Windows 10 upgrade From 8.1

Hi,

Welcome to Microsoft Community.

I understand that you have a question in merging the partition.

I would like to inform you that you have an option of merging the drives with simple changes from the issue description. Do not merge the EFI system partition as it deals with the boot process. Also I suggest you reserve a drive so that you can retrieve
files of Windows 10 when needed.

Create a recovery drive

Create a recovery drive - Microsoft Support

Now you can merge four drives out of six.
To do so refer the steps below.

• 
  You can do that by right clicking on the drive.
  
• 
  Select Expand and follow the on screen instruction.
  

Hope this information helps you.
