Windows 10: 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?

Can't format flash drive to FAT32 in Windows 10

I tried the Free version of AOMEI Partition Assistant. It mis-reported my hard disk - The partitions with ext4 file systems were labeled as "unallocated".

My 4GB USB drive has a GPT and two partitions. The first is the UEFI System Partition and the second partition has a FAT32 file system.

Partition assistant reported my USB drive as 2 different drives.

 

No "Windows Boot Manager" entry of Boot Configuration of UEFI for Surface Pro 4

The only way I'm aware Windows Boot Manager will not set itself first to boot on a UEFI System is if it was installed in CSM or Legacy Mode. You can tell this in Disk Management by the presence of the legacy Active flag on System partition and lack of an
EFI System partition, or type msinfo in Start search to look in System Information at BIOS mode.

Sometimes the settings in the UEFI firmware are sparse and the only determinative for UEFI install is if the installation media is booted as a UEFI device and all partitions deleted down to Unallocated Space to reset if necessary the disk formatting from
MBR to GPT required for UEFI install.

The normal UEFI settings in BIOS are CSM, Legacy BIOS, UEFI, and under Boot Priority order. If you want to report back those settings choices we can help interpret them.

If the Windows Boot Manager was deleted from the list then you may need to Reset UEFI Firmware to Defaults using that choice wherever it appears - check all tabs.

 

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 .
EFI system partition - Wikipedia

 

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.

 

They are out of order compared to my systems. The hidden 450 MB Recovery partition is normally the first partition on the drive, then the System OS partition, then the hidden EFI, then the D: drive. I delete all but my Data drive/partition and let Windows create what it wants where it wants.

 

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?

 

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

 

Yeah, I just do it via the Windows setup/custom install option.

 

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.

 

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.

 

I don't know what to tell you Jack? I did the same swap on my wife's Acer laptop and didn't have to change any BIOS settings. Secure boot etc is enabled by default on both laptops. My 2 desktop PC's are just legacy BIOS. No problems installing Windows 8 or 10 on any of them. The only BIOS setting I change is boot order to do the install.

 

Yeah weird for sure , I actually had 2 of the same acers at the same time ,and had to do it to both of them,
2 weeks ago now ,,so I don't remember what changes I made ,but I will boot the one I still have with me ,later to see what it was ,,

 

well i went into the bios and set it to defaults and it booted with out issue , last week it would not boot till I disabled a few item ,like launch csm to never ,and disable quiet boot ,, before I did that it would not boot to the usb , or even boot to windows after I installed ,, now it boots fine set to defaults . boots to desktop in 22 seconds .....who knows not I
