Multiple C: drive partitions related to windows boot

Hi. I need help identifying which of the partitions i can format that is not in use. There should not be that many of them, something went wrong and there are remains from old installation in some of the partitions, i believe it should only be 4 in total? Please review the screenshots and tell me how i can safely identify which i can delete. I have AOMEI Partition Assistant

Can you post image from disk management.

This is what I would do:

I would install Macrium Reflect (trial version would be ok) and create a usb rescue drive.

Then I would image backup all the four partitions.

Then I would delete all three of the four partitions (keep largest), and boot from Macrium Reflect and use its "fix windows boot problems".

It will then delete the bcd and rebuild it, and you should only have one efi partition.

If this fails, restore the four partitions and we can try other ways.

Hope this helps

I just came up with an idea! Here you can see what matches the one in AOMEI Backupper, they match in size, does that mean that i can safely delete the other ones that dont match the same size? Im making a backup anyway so i guess there are no risks involved, just a tad tedious if i need to restore again. EDIT: forgot to show screenshots with comparison

at admin cmd prompt type

reg query HKLM\SYSTEM\CurrentControlSet\Control /v FirmwareBootDevice

(then press enter)

i deleted one of the partitions and its all good but i have 2 of 68.88 mb ones, should i have 2 of them or only 1? And i have yet to delete one of the bigger partitions, im not sure which of them i shall delete yet, of course i should save the one with the same size as the backupper but i think bing chat said that usually it creates 2 of them (im talking about the 916 mb ones) so im scared to delete the other ones. Anyway hope you can figure it out for me

On a EFI-GPT drive you should have:
- One EFI Fat32 100M partition
- One MSR RAW 16M partition
- One big C: NTFS partition
- One EFI Fat32 100M partition


How did you get 4 EFI Fat32 100M partitions and 5 EFI Fat32 100M partitions?

Exactly! lol

Even easier run:
reagentc /disable

Delete both recovery partitions, then run:
reagentc /enable

You will still have the mess of all the EFI system partitions to deal with though.
