Windows 10: Clean install UEFI only 3 partitions

hi all I have clean installed windows 10 in UEFI mode it showed 4 partitions but after install only shows 3 partitions in disc managment no MSR reserved partition why How do I know it is UEFI mode

:)

 

DATA ERROR: CRC

Hi! I've done everything above. I deleted partition, it's the only drive and only one partition when I bought it then I decided to create a D partition and clean install windows. but after I deleted the partition it say that windows cannot create partition.
even on DISKPART, CRC error returns whenever I do the Disk Cleaning was successful but creating a partition returns the crc error.

also. the windows installation only initiates when in CSM BOOT, the media (adata 16gb 2.0) was not detected if I set it to UEFI.

 

Windows 10 Bootable USB, need help with setup

Make sure you backed up all of your data and made the other prepartions from the checklist in

Clean Install Windows 10 .

Then follow the illustrated steps in the link to boot the media as a UEFI device only, during Custom install delete all partitions down to Unallocated Space to get it cleanest, then easiest is to click Next to let the installer create and format the needed
partitions and begin install.

Replace media if it will not offer UEFI since we know you have UEFI by the EFI System partition). Not deleting all partitions is
not a Clean install and builds up a disk junkyard.

Feel free to ask back any questions and let us know how it goes.

 

In my system, disc management shows 3 partitions. The second one is a 100 MB EFI one.

The diskpart utility shows a fourth one that is hidden from Disk Management.

I'm pretty sure that I have a UEFI install.

 

To know if you are installed naps UEFI or Legacy mode, simply look at the disk info for the disk which Windows is installed onto.

In the Disk Management utility, right click on the system disk (Disk 0) and open properties. Check "Partition Style" under the "Volumes" tab.

GPT means UEFI mode, no exceptions.
MBR means Legacy mode, no exceptions.


If installed as UEFI (you likely are) you should look into trying to disable the Compatibility Support Module (CSM) also known as legacy/bios emulation, if your BIOS supports disabling it. This will speed up the boot process substantially.

If installed in Legacy mode, I suggest you reinstall in UEFI mode.
