Cool. I'd read the process and make sure you understand how to do everything before beginning. You will not have to reinstall Windows.
1) In Disk Management, assign a drive letter to the recovery partition. Make it R: (Leave Disk Management open.)
2) Ensure hidden folders/files and system files are visible in Windows Explorer.
3) Copy the bootmgr file from R: to C:
4) Copy the Boot folder from R: to C:, ignoring the warning about how it can not copy bcd or bcd.log. Tell it to skip these files when it asks.
5) Open an elevated command prompt. Copy and paste this command to it then hit enter:
Code:
bcdedit /export C:\Boot\bcd
Make sure and double check that bootmgr file and Boot folder are now at C: root and bcd file is inside Boot.
6) If it went well, go to disk management and set the C: partition as the active partition.
7) Reboot.
8) Format R: in the normal way. Quick format is fine. Then use Acronis to merge R: and C: together.
Let us know how it goes for you or if you need further help. Good luck. Post a screenshot of Disk Management after if you'd like to.
