Windows 10: MBR or GPT ????

hello,
I had my 120GB SDD replaced by a 480GB one and made a clean install of win10
got an adapter to use the small SDD as an external backup disk
I get a window demanding that I initialize the disk
I do not have a clue what I should select...MBR or GPT ? *Huh
I intend to back up my C drive with Macrium Reflect (following the tutorial careful step by careful step !!!)
so... what should I select, please... (and why, if it's not too complicated to explain)
thanks *Smile

Windows Installation

On EFI systems, Windows can only be installed to GPT disks. If you use MBR disk, you will receive this error message: Windows cannot be installed to this disk. The selected disk has an MBR partition table. You can convert MBR to GPT and try it again.

 

Convert only one partition on the disk from MBR to GPT

Step 2
Convert MBR to GPT without data loss

 

Honestly, it really doesn't matter.

GPT is required for larger disks (there is a limit on MBR of 2TB) and is also a requirement (sometimes) for EUFI booting. You are talking about a small backup disk.

I would use GPT for the simple reason it keeps 2 copies of the partition table - one at the start and a recovery one at the end. MBR doesn't. If you get partition table damage you are more likely to be able to recover it on GPT formatted disk.

 

MBR is also limited to 3 Primary partitions, then you have to use Logical partitions, which are not bootable. GPT has no practical limit on number of Primary partitions.

MiniTool and utilities like it can convert MBR > GPT, and vice-versa.

 

Thanks to both of you !
since you concur on GPT, that's my choice !

I use a different Cloning program and always make a sector by sector copy of the entire disk so I always use whatever the source disk in initialized.

 

Hi,
GPT on a 120gb ssd is sort of silly it's too small all it needs is a system reserved and MBR that's all.

 

It's a data drive not a boot drive...
