Can I use MBR to boot Windows 10

I have a M.2 installed on my MSI motherboard. Can I use MBR to run the OS or must I have to use GPT format. Need some advice.

Thanks.

 

You could.
But for an M.2 SSD GPT is what the doctor said.

 

MBR is fine for sub 3TB disks.

 

It's rare to find motherboards these days that still have UEFI booting bugs, so I'd recommend GPT nowadays.

 

Thanks for all the suggestions guys.

Basically, my system configurations -

* Intel i5-9600K with 16G ram
*Z390-A-Pro
*MSI RTX 2070
*Boot drive is a Adata NVMe ADATA SX8200PNP
*3 X 4TB Toshiba HDDs

With the above, can I format the Adata using MBR with the rest of the HDDs in GPT format?
Or, use all the drives in MBR format.

 

Is there some reason you need to have your boot drive in MBR rather than GPT

 

GPT for 64bit Win10 AND UEFI [PCs & motherboards made in late 2012 or newer]
MBR for 32bit Win10 with traditional/legacy BIOS (or UEFI-CSM)
MBR for 64bit Win10 and legacy BIOS (non-UEFI) - I have some really old PCs running Win10 with this config that don't use UEFI

 

I was wondering the same thing?

 

Buggy mainboard firmware that doesn't do garbage collection on the EFI variables. Long story, but this results in not being able to boot when an OS writes new boot entries. Happened to me in the past after a Windows update. Modern mainboards should be fine though.

 

If this is the Motherboard https://www.asus.com/ca-en/Motherboards/TUF-Z390-PRO-GAMING/ that greeny187 is referring too, there is no reason this motherboard wouldn't boot from a GPT formatted disk?

Should you select MBR or GPT when you install a new drive?

The Windows installation (USB thumb drive) media may limit the ability to install the operating system in one of two UEFI bios mode settings:
1. CSM enabled: required for "Legacy" (MBR) partition mode.
2. CSM disabled: required for GPT partition mode.
If the free 3rd party software "Rufus" is used to create the Windows installation media, then certain options need to be selected, in order to assure creating a bootable USB thumb drive in CSM enabled vs. CSM disabled mode.
If a bootable burned DVD is created from the Windows .iso file, then it should be able to cope with either CSM enabled or CSM disabled mode.
