NVME MBR or GPT ? im confused

[xtasemusic]

So I installed an NVME drive 960 evo in my PC and now windows wants me to initialize it . MBR or GPT ? I will eventually make it the boot drive and my MB ( X99S SLI PLUS says *Intel RST does not support PCIe M.2 SSD with Legacy ROM.* on the website Im not sure what im supposed to do.

GPT. If your system supports NVMe, MBR is obsolete for your system, there's no reason to use it.

1.Open the Command Prompt. This can be done by triggering the Run -- Windows Key + R -- feature, and opening "cmd".
2.Type "diskpart" to open the disk partitioning software. Accept the UAC security prompt, if asked.
3.Type "list disk". The program will then show you a list of all the physical drives (HDD, SSD, USB, etc.) that are attached.
4.Identify the disk number of the SSD (it can be recognized by looking at the size column; it's usually the last listed disk) and type "select disk X", where "X" is the disk number of your SSD.
5.Type "clean". This will erase the contents of the SSD, so make sure you have the contents backed-up (if any) beforehand.
6.Type "create partition primary". This command will create a primary partition on the SSD.
7.Type "select partition 1". This command will select the created partition.
8.Type "active". This command will make the selected partition active.
9.Type "format fs=ntfs quick". This command will format the created partition as NTFS.
10.Type "assign". This command will assign a letter to the SSD, which will make it show under Windows Explorer.

the biggest difference between them is the max partitions you can make on it. 

and what you want to do with the drive.

 

 

I found out that you can't clone GPT with a lot of cloning software. from corsair to intel SSD clone software, 

to aomei that only free clones MBR, 

corsair tells you after the first 2 partitions that an thirth is inpossible on an ssd. then reverse everything.

the aomei software just says they won't changes the format files for free. 

 

and manualy change to MBR can damage the files in the drive.

 

OS on ssd?

first did it sound logical to take the same settings as the ones of the OS (GPT) DON'T it doesnt work, MBR works better with ssd's

 

choose MBR

make a back-up form your hhd

make a windows reset on a usb

then set a clean install on the ssd

and use the back-up to recover youre files

If your system is 32 bit, you have to use MBR for GPT does not support 32-bit OS.

That's not true. The not booting from 32-bit restriction applies only to Windows 7 or earlier.

MBR is also limited to 2TB maximum partition sizes.

thanks a lot guys ! I had some issues here and there but I went for GPT + had to update the BIOS on my MB because  windows saw the drive fine but the bios didnt even show it in board explorer , I was even able to install windows on it ( when inside the bootable win 10 usb it saw it but couldnt boot from it ). anyways after the bios update all is good and smooth.

You can't boot from NVMe in Legacy mode, so GPT is the only way to go (because MBR isn't supported in EFI booting). With AHCI drive, you can go either way (gpt/mbr).
