I did a clean install on a new SSD that I had previously formatted and neglected to delete the partition ending up without a MSR partition. I've already installed lots of applications so starting over would not be something that I'd want to do. What are possible problems that I could be looking at going forward?
On a clean install using GPT partition scheme, you should have:
- 450MB reserved partition
- 100MB EFI System partition
- 16MB MSR Partition, needed with GPT disk to function properly (Hidden from Disk Management, use dispart to see it)
- The rest is C: Drive
To see this partition, open Admin command:
- diskpart
- list disk
- select disk # =====> # is your Win OS drive
- list par
- exit
Good luck !!!That hidden partition/space is not required for a GPT to function properly. I deleted it from my system when I customized my recovery partition.

Here's my installation with no System Reserved Partition. This was not deliberate on my part but rather the result of too many distractions during the installation of the new SSD and not focusing fully on the Win10 install. First the new carrier for the SSD didn't align with the holes in the case so out came the Dremel tool. With the new SSD in place I formatted and created the overprovisioning partition with Samsung Magician. Then I installed Win10 forgetting to disconnect the old SSD with Win7 on it and not deleting the existing partition from the new SSD (a double dumb mistake) ending up with a dual boot. Definitely not what I wanted. Then I wiped the old SSD and deleted the Win10 installation from the new SSD not realizing that the boot info resided on the old SSD. So after reinstalling Win10 no boot. Yet another dumb mistake; I was on a roll! I was able to do a repair of Win10. So that's how I ended up with no System Reserved partition. I also forgot to set the new SSD as the priority internal boot drive in the BIOS adding yet more fun and frustration to the day. At least all of this kept me off the road so I couldn't kill myself in an auto accident!
I thought this was a story worth telling just for the lesson of stepping back and taking a deep breath when something goes wrong. Insofar as the lack of a MSR partition is concerned, the only consequence I can see is not being able to use bit-locker in the future. Anyone disagree?
If you are not using Bit locker then it is fine as is. However, I suggest to swap the cable in your PC to make the C: drive to be on the first sata port ie. disk 0
