    Yeah, type is the EFI System Partition (ESP for short) of your GPT disk. Delete that and it won't boot.

    I already know that Word Man, never even thought about deleting that partition. But it does not say ESP, but like I said yesterday, on another users pic, way over on the left hand side, same line we are talking about, it DID report that it was ESP. Mine most likey used to also show that too, but after I changed, and removed the restore partitions, it also changed some of the wording that was originally displayed, why, I don't know.

    Still thinking about doing a clean install thou, just not thrilled about having to re-install all my registered apps. I've only had this computer for about 4 days, bought it on ebay over a week ago, was originally installed with windows 8.0 then the owner upgraded this computer to Windows 10 Home. I have no use for the Home version, so I bought a license for the Pro version, then upgraded this OS to Windows Pro. But, I am thinking I need to do a clean install, because of some of the crap left on here by the original owner.

    That was the volume name of that person's ESP partition. The volume name of your ESP partition is "SYSTEM", as shown in your MiniTool snap.

    You're asking which partitions you really need and you've had lots of input from others, including mine. You said it booted fine after you deleted the first 1GB recovery partition and I simply followed by saying it won't boot if you take out the ESP - more input as to which partitions are necessary - I'm assuming YOU consider the ability to boot as NECESSARY.

    A clean install is a good thing. You will get 3 partitions (including that pesky ESP partition) and an unallocated MSR along with it though, assuming you stick with structuring your disk as GPT.

    well I just tried a clean install, on my new computer, it asked for my key code, which I entered. This is not a free upgrade type of install, because this system was windows 10 home, now its Pro. Everything seemed to install ok, lost all my installed apps.but never did any changes to my partitions. Their just as I had before.??? So I did something wrong.....

    See Steps 10 & 13 in Brink's Tutorial here: https://www.tenforums.com/tutorials/1...n-install.html

    That's where you can blow away all existing partitions and get a start from scratch install of the partitions that Microsoft thinks you "NEED" (your opinion of what YOU need will no doubt be different). The old partitions will be gone.

    Right - if you want to stick with MBR and not UEFI/GPT scheme (assuming your machine allows either) then go Step 12 instead of 13 - here Brink says if you format the entire disk ahead of time, you will NOT end up with any other partition(s).

    Ok Word Man on my 2nd try, I found where I can delete the partitions, windows was highlighting only my main drive, and I didn't try to change anything. 2nd try I looked a lot closer at my options, moved up to the other partitions, deleted, them 1 by 1 then hit enter, thought windows would ask which format to use, didn't?? so I stopped installation, windows went back to the original setup screen, I started the install all over again, this time it showed me the new partitions it made, so I am letting it go thru with this install.......didn't see a choice for choosing MBR or GPT, but this computer defaults to GPT anyhow. this is my old computer I am on right now. New one is going thur the install, 3rd try....:)
