Windows 10: Windows will not shut down, restart or go to sleep after new EFI and MSR partitions were...

Hello,


The title says what my problem is essentially, except that I am actually able to shut down my system when fast startup is disabled.


What happened? I tried to install a dual-boot system by installing Linux on a clean drive. Once Linux was installed, I was unable to start Windows 10, probably because Linux messed with the boot process of Windows. Creating new EFI and MSR partitions on my Windows startup disk using the command prompt resolved the startup issue and my system functions just as before, except for what we are now discussing.


I wonder if maybe boot manager or another startup program is confused by an excess of EFI and MSR partitions? Could it be that the unallocated spaces below are the old EFI and MSR partitions and should be deleted so as not to interfere with the startup process? Or could it be that the partitions created in the command prompt are not up to task?


At the moment, my startup disk looks like this according to Disk Management:




Diskpart returns the following partitions on this disk:




Thank you for any input that you may have.

Expanding EFI partition and moving MSR partition.

I would like to install Mac Os on this device. However I am limited by the size of the EFI partition. Mac Os requires at least 200mb. I have only 100mb. So I resized the Windows partition to leave 100mb unallocated. However I can't extend the EFI partition
because there is a MSR partition in the way. https://puu.sh/rFbsz/e52c847706.png

I know both the EFI and MSR partition and very much required partitions for proper functioning and it is better to not mess with it. But I have to get the EFI to 200mb. So how to move the MSR partition. I am pretty familiar with DISKPART or other GUI based
partition managers.

Issues with MSR Partition

Quick question, Greg: Does the setup.exe file on the Windows Install Media fix the EFI partition, create a new MSR partition, fix the GPT, etc? Sorry if that question was badly worded or incorrect.

 

Need Help Restoring EFI and MSR Partitions

Hello,

I think that for some reason, my EFI and MSR partitions were not located on my main Windows drive.

When I installed linux mint on a separate drive, Windows refused to boot. I did the usual linux chain of debugging like boot-repair and update-grub but I don't think that's where the problem is.

Upon investigation in both linux and diskpart on a recovery cd, my Windows HDD is missing a EFI partition and a MSR partition. It only has the main data partition and a recovery partition. Even more interesting, there is no unallocated space on the Windows Drive so the EFI and MSR must have been somewhere else. I believe the EFI and MSR were on the drive I installed Linux to for some reason, and they were overwritten.

My plan now is to format the recovery partition and put an EFI and MSR partition there and then restore using start up repair.

I need to know if

a) this will work? (EFI and MSR won't be at the beginning of the disk) and
b) how big do I need to make the partitions for 64bit windows?


Thanks.
