Booting and partitioning of GPT for Windows 8:
  1.Boot from the Windows 8 install media (You must initiate this boot from a device labeled as a UEFI device, or the installation of Windows 8 will produce an error that the OS cannot be installed to a GPT partition) These UEFI boot devices will have a prefix UEFI: "name of your device", and show as a boot option in your UEFI.
 2.After booting to the UEFI device you see the Install Windows 8 screen, press Shift + F10 to open a command prompt.
 3.Type Diskpart, press Enter
 4.Type List Disk , press Enter
 5.Type Select Disk # (where # is the number your drive shows up as), press Enter
 6.Type Clean, press Enter
 7.Type Convert GPT, press Enter
 8.Type Exit, press Enter.
 9.Close the Command Prompt window.
 10.Click the "Next" button.
 11.Click the "Install now" button.
 12.Put in your product key and click the "Next" button.
 13.Accept the terms and click the "Next" button.
 14.Choose "Custom: Install Windows only (advanced)."
 15.Select the partition and click "Drive options (advanced)"
 16.Click "New" and then click the "Apply" button. Four partitions should appear. Click the bottom partition.
 17.Click the "OK" button and then click the "Next" button.
 18.From then on follow the on screen instructions till you get to the desktop.
Note: If you can't boot after the install you need to make sure the boot is set to "Windows Boot Manager" in the UEFI. Also, important info.

Has anyone tried this setup using Windows 10? Also, what exactly is the benefit from using this setup option? Will Windows bootup faster with less bios boot screens to look at?

See this link: http://www.howtogeek.com/193669/whats-the-difference-between-gpt-and-mbr-when-partitioning-a-drive/

Or....the general idea is that GPT is used with UEFI systems and allows for faster/quicker boot times.
MBR is the old standard that was used by systems since the mid 1980's. It has some limitations that now-a-days could be a bit of a problem so to speak.

Anyway...long story short, if you have a newer system with a UEFI bios and are running Windows 8/8.1 or Windows 10, it would benefit you to use a GPT partition to get faster boot times. :)

One of the main advantages of using GPT is the ability to work with drives larger than 2TB. If you are sure that you would not cross 2TB on a single drive then MBR would be fine. :)

Hello,
 sorry I am French and my English is perhaps not technical gutter that's why I used the French-English translator thank you in advance!

Starting off with specs:
MSI Z170M MORTAR, Socket-1151
Intel Core i5-6600K CPU @ 3.5GHz
DDR4 2133MHz 2*8Gb 16Go
SSD 250 Go 2,5 pouces SATA Express
Hard Disk 3 To GPT SATA Express 
Intel HD Graphics 530
Keyboard & mouse USB

Running Windows 10 x64


When intallation of Windows 10, we wonder drivers for the card but without specifying which.
Having put the dvd MSI I seek new.
There is no driver that corresponds to his request!

even guiding research towards drivers directories!(I/O Ports, Network, Sound, Storage, SVGA, USB, otherdiver
I'm stuck at this level

Second, I install a hard disk 3 TB with a GPT partition EFI? But this partition is either hidden or it does not dispode same partition letter with windows 7?
I was able to then install a hard drive with a 3 Tera GPT partition, 1 To 5 and 1 To 3
What can I do without losing the data it.

The backup is impossible since the partition is not recognized!

Thank you

More way:
1 - Boot into windows setup screen. Press shift+f10
2 - diskpart
3 - select disk < disk number >
4 - clean
5 - convert gpt

Close command prompt, choose unllocated and press next.

Convert MBR to GPT using Diskpart
  • Open command prompt and type in DISKPART and press Enter.
  • Then type in list disk (Note down the number of the disk that you want to convert to GPT)
  • Then type in select disk number of disk.

I just want to notice this program for who made some mistake and think they lost their datas with a wrong tip. To bring back a lost partition u can easily use Testdisk. This program is downloadable on internet for free.
