Windows 10: What is the process of recovering from deleting the recovery, efi and msr partitions?

Rather than reinstalling I want to learn about Windows utitlities and the Command Line. I'm assuming that between the 3 partitions that I removed, the recovery partition is the least necessary. I haven't tried to restore it. Here's what I've done so far to recreate the efi and msr partitions. What's been frustrating is that tutorials don't tell you if their process is for legacy boot/MBR or EFI/UEFI systems. Please let me know if I'm missing anything:# Booted on to a Windows 11 iso and launched the Command Line terminaldiskpart# Choose the disk where Windows was installedselect disk 0# Create

How to install Win10 when the Recovery & EFI partitions were deleted?

There are a couple of issues with the above sequence. First, @drpeppercan stated that they already deleted the EFI system and recovery partition. So why is there a select part 1 and delete part override in the command sequence? What is being deleted? The Microsoft System Reserved partition? Hopefully there is an MSR partition there because if partition 1 is the Windows OS partition, then you just deleted Windows. And if there is an MSR partition there, why delete it?

Second, without a size specified when creating the EFI System Partition, it is just going to fill all available free space at the beginning of the drive. If there was a recovery partition, EFI System Partition and MSR partition, that free space is likely to be 600 MB is size, so you just created a 600 MB EFI System Partition that only needs to be 100 MB in size.

Without seeing the layout of the disk with: select disk 0, detail disk, list part you can't really suggest an accurate list of commands to rebuild the EFI system partition. It's only guessing.

 

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.
