Partition Question - First UEFI system

So I just completed a clean install on my new Pavilion X360 laptop. I've been building computers and working in IT for 20 years, but I've come across something I haven't dealt with before.

I'm always used to using diskpart to set up my drives during the OS installs. I used the same process on this new computer, including the convert gpt option. I was able to partition my blank 840 EVO SSD and install Windows 10. I'm a little obsessive compulsive about partitions, where I like as few as possible. Normally, I would expect my drive to show two...C and D. This is what my SSD looks like now, and I believe one of the two unlabeled partitions is necessary. Is this true? Can I delete either one, or are they necessary and I should leave it be?

they are necessary to the best of my knowledge ,,so just leave them be .
1 is for win10 recovery if something goes wrong .and the other is ,see link
efi 100meg partition .

Ah, that's what I was referring to for the EFI partition. I thought I remembered reading somewhere that it is necessary. Quite the change from the MBR drives I am used to. Thanks for the link.

it is a big change just getting use to it my self , good luck with the new setup ..

,wait till you need to change a dead hdd ,and the new bios wont let you [security reasons or something ],till you make all kinds of changes In the bios ,now that part still has me puzzled

I cleared the drive in diskpart, then converted to gpt, then created the system partition in consecutive commands. Maybe creating the partition in the Windows setup would explain the different order?

Here you go some information about the default setup directly from Microsoft: (Also links to sample to automate setup.)

Configure UEFI/GPT-Based Hard Drive Partitions

I personally, used a setup script to create a 100MB WinRE partition, 100MB EFI partition, everything else went to the Windows Partition. Did not create the "Microsoft Reserved Partition" in my setups.

I swapped out the Spinner drive on my laptop (UEFI) for an SSD and didn't have to change any BIOS settings?

its happened to me on a few computer now ,one I have in front of me I got for nothing because the owner had it check and was told the motherboard was like dead ,it would not even turn on , but the power plug was not plugged all the way into the motherboard plus the hdd was dead ,

so I added a hdd that I had lying around ,and just got reboot to pick media device error message ,until I pulled the bios battery and got it back to defaults , it boot to win10 usb ,but showed no hardrive to pick to install to ,until I went into the bios and disable a bunch of things ,,

got it to work and installed windows ,went back and set bios to defaults and it would not boot again till I went in and made the changes again ,,

so left them at that and it is working now for about 2 weeks with those settings ,can remember what all[ at least 3 different ones ,, ] the settings were now.
