That's some fine mess he got into.
First, G: partition shouldn't have a letter as it's system BOOT partition, G:letter can be removed right there from Disk management, right cick on it and Change or remove letter. That should take care of it.
Other one is more difficult but https://www.partitionwizard.com/download.html can help.
100MB Partition should be moved using that program to before C: so unalocated one is next to C:
Than you can format that one to same format as C and than you can merge them easy enough with same program.

It is not BOOT (bootloader) partition.
It is regular basic data partition. It was bootloader partition before conversion from MBR to GPT.
Now it is just a useless remainder of old bootloader. Partition G: can be deleted.
100MB Partition should be moved using that program to before C: so unalocated one is next to C:
Than you can format that one to same format as C and than you can merge them easy enough with same program.
It's actually better to delete 500MB and 100MB partitions.
Create a new EFI System partition, where old 500MB partition was.
Then extend C: to full size of the disk.
Note. You can delete EFI System partition (active bootloader partition) only, if you boot from windows installation media.
If you try to do that with some 3rd party partition management software, you'll make your system unbootable.

Do not merge anything! Merge operation should be avoided. You can loose/corrupt all your data with merge,
And merge is not necessary here.

Boot from windows installation media into command prompt (press Shift+F10, to open command prompt) and
execute following commands.
If you get any errors then stop immediately and show screenshot.

diskpart
list disk
select disk x
(select 3726GB disk containing windows OS partition)
list partition
(if windows OS partition was not listed, then you have selected wrong 3726GB disk)
select partition 3
(select 100MB partition)
delete partition override
select partition y
(select 500MB partition, y=1 or y=2)
delete partition
create partition efi size=500
format fs=fat32 quick
assign letter=K
list volume
(find drive letter for 2047GB Windows OS partition. I'll assume it's M: )
exit
bcdboot M:\windows /s K: /f UEFI
Last message should be "Boot files created successfully".

Shutdown, remove windows installation media, boot into windows.
Now you should be able to extend C: to full size of the drive.

Hi if i Boot from windows installation is there any way i can remote into the pc?
Remote would have to be set up and this is messy enough already.

To be honest, while Skynet's advice is excellent, it also requires a bit of comfort with the technical side. Without knowing the expertise level involved and considering a mess was already made of a simpler task, my advice would be to make sure all important data is backed up -- something that should always be done anyway -- format the OS drive and install a fresh WIndows.
 
hi, can i use https://www.partitionwizard.com/download.html to move the uefi where g: is?
Try it.
Keep in mind - if something goes wrong with partition move, your system becomes unbootable.
You'll need windows installation media to fix it.

So have it prepared. And make sure, it works.

BTW - I don't think, you can move a partition to opposite side of another existing partition.
You could do partition copy.
But then again I'm not sure, if partition wizard can copy efi system partition properly.
It will probably become a regular basic data partition.

he had a 1 tb hd it was in mbr it was clone to the 4 tb then mbrto gpt was used
Yes, I know that is what he told you, and you are now telling us.

But we out here do not know the starting condition of the drive and its contents, or whatever else he may or may not have done.
What clone tool was used? What settings in that tool? etc, etc, etc.

But all that is mostly irrelevant.
It is what it is right now.
