In internet you can find different methods how to recreate MSR partition, but I suggest to reinstall your Windows 10 (and this time correctly). You can use the following tutorial: Windows 10 Forums .
Since we want Windows with UEFI partition, skip on para. 12 and go directly to para 13. First delete the old partition (para. 13.A) and then create the new partitions (para. 13.B).
