Windows 10: Do I really need a Windows 11 Pro MSR Partition on my hard drive?

I had to create a larger MSR partition because an in-place upgrade would not work without expanding my EFI partition, which required deleting the old MSR partition then creating a new one after enlarging my EFI partition. I have had problems doing this, and in the process discovered my PC will boot just fine woithout any MSR partition at all. In researching this I found a lot of conflicting information on this issue. Can anyone point me to a Microsoft definitive answer on this question?

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Help with MSR partition on secondary drives

I have two secondary hard drives that have MSR partitions on them. I want to use them in another setup but dont want conflict if possible because of partitions. I also dont want unneeded partitions. Both drives have partition one as MSR. Do I need to delete
these, if so, do I extend my main partition? Any help is appreciated. Thank you for your time.

 

Windows 10 Hard Drive(GTP) wont boot up after formatting Recovery, Reserved(MSR) and system partition.

I made a bootable Windows 7 USB (32 GB) and booted my pc with it, in the installation menu it was asking me to choose a partition out of the 6 partition from my
main hard drive (1TB) not the USB (32GB) on which it was booted on.

The six of partitions of my hard drive which were shown are -

1. system partition (100mb)
2. Recovery Partition (499mb)
3. Reserved Partition (16 mb) (MSR)
4. my c drive
5. my d drive
6. my e drive

I didn't think anything and formatted the first 3 partitions, the system, Recovery and the Reserved(MSR) partition, i didn't notice anything until i decided to reboot my pc
after un-plugging the bootable USB. When i started my pc without the bootable USB it was giving me an error which said that it didn't detect any bootable hard drive, so i plugged my USB and tried to fix the the hard drive from cmd. I have watched
Hundreds of videos since then, tried to change the boot modes (UEFI / LEGACY ), un-plugged and plugged the hard drive twice, tried the system reserved partition fix, but nothing solved my issue ( i was trying to fix my main 1TB hard drive from the bootable
USB, because the hard drive won't boot), after reading lots of posts and watching all those videos, i think i have some idea that what might have happened, i think i
formatted the three hidden system partition, which I wasn't supposed to touch at all, and that had all deleted the booting mechanics. I tried a lot of fixed, at one point i
deleted ( not formatted) the 16Mb MSR reserved partition and re-created it (it was empty anyways and i was desperate) but it didn't help. I don't want to reinstall a fresh windows on my hard drive because I don't want to lose data. Is there
any way in which i can boot into windows again with my hard drive without any data loss?

Addition info -

• I have a GTP hard drive
• My pc doesn't have system reserved partition, it instead has a different system and reserved (MSR) partition.

Please ask me if i didn't make anything clear.
