Windows 10: UEFI/GPT-based hard drive partitions default layout for windows10

Hi there,

I have been currently looking in my laptop the default windows 10 partition layout which seems to be very odd in my case. well, i was recently reading an article here:

UEFI/GPT-based hard drive partitions | Microsoft Docs

and saw that the default partition layout for uefi systems, which is a way different case with me. here is my layout.




As in my layout, the first partition is new volume f which used as storing user data and then i have efi, then C, then oem which is why i am asking here, is it good or bad to have this type of layout.

let me give more info now, i clean installed windows 10 a way months ago deleted some partitions and left the efi and some recovery partitions which was of oem recovery win8 backup. but after certain time i deleted that oem backup because obviously, why do i need win8 when we have win10 now. from which that F partition got stuck in the first place.

the good thing is everything runs fine in my system but sometimes randomly it just runs like hell slow and sometimes fast like a speed of light(not so fast, just joking) and the second thing is when i boot my laptop, the dell(manufacturer logo) boots twice to boot into system(let me explain this in the steps if you don't understand, at first the dell logo appears but with no loading, then it goes, then again dell logo appears and loading begins and finally i am in the system). the funny thing is that this has absolutely no effect on system(according to me).

can you help me with this if you understand what i am saying. i would greatly appreciate the help

Windows 10 installation on 4tb hdd on GPT partition with UEFI mode system.

Hi Troy,



I realize the inconvenience you are experiencing with Windows 10. I will certainly help you.



This issue might occur if Windows 10 is not correctly in GPT partition with UEFI mode.

I suggest you to refer to the suggestion provided in the Microsoft Help Article and try to install Windows 10 in GPT partition. Check if it helps.

GPT Partition Style

Hi,

Do you want to install Win 10 Pro to Legacy Bios or UEFI Bios settings...

That is where the "GPT" comes in... It is required for UEFI Bios, and "MBR" is required for Legacy Bios...

How the Flash Drive is created can also determine how the installation tries to install... If it is created with a NTFS file system it will most likely try to install for Legacy Bios and look for a MBR Drive...

It is created with a FAT32 file system it will most likely try to install for UEFI Bios and look for a "GPT" drive...

You can not simply have a "GPT" or "MBR" partition... The entire drive must be GPT or MBR created when the drive is first "Initialized" after having every partition on it deleted...

If you can determine if the machine is set for UEFI or Legacy it would be easier to help... One thing to check for... If you have a small FAT32 "EFI" partition, it is UEFI Bios... If you do not, it is Legacy...

 

Convert Windows 10 MBR to GPT (UEFI)?

In reviewing my Windows 10 Pro (64-bit) system I noted that the Secure Boot Status is showing as "unsupported". Investigating further, it appears either the GPT partition for booting using UEFI (is Secure Boot) has become corrupt or my installation was
never installed for Secure Boot. My Windows 10 install is an auto-upgrade from a Windows 8.1 install.

Is there a way to convert the MBR to GPT without doing a fresh install? I do have a USB recovery drive built at a point I believe I had indications Windows was booting from a GPT (UEFI) partition. In fact, the USB recovery drive shows as being a UEFI drive.

Any suggestions will be appreciated!

Thanks!
