Windows 10: Win10(GPT) / Win7(MBR) dual boot BIOS settings (Gigabyte Z170m-D3H)
Win10(GPT) / Win7(MBR) dual boot BIOS settings (Gigabyte Z170m-D3H)
I'd like to apologise in advance as this is probably completely newb to many of you.

My Windows 10 boot SSD is GPT format while my Windows 7 boot SSD is MBR format with System reserved partition so IDK if this is even possible for dual booting?
I'm not sure if other OEM's have this feature, but the UEFI BIOS allows you to exclusively enable your boot drive, so you can have multiple drives with distinct OS's, and when you choose to boot one, the others are auto-disabled.
I don't get where the the settings on "exclusively enable and auto disable" are and how to apply them...
Can anyone show screenshots of the settings to enable safe dual booting?

Reason: Trying to get title right
Would I be on the right path in thinking 2-4 of the manual (BIOS Features) is what this guy meant?
Wouldn't this create a palava when trying to choose which OS to boot given Fast boot disables accessing BIOS with the Del key after posting?
Enables or disables Fast Boot to shorten the OS boot process. Ultra Fast provides the fastest bootup speed. (Default: Disabled)
>>All Sata Devices All SATA devices are functional in the operating system and during the POST. (Default)
>>Last Boot HDD Only Except for the previous boot drive, all SATA devices are disabled before the OS boot process completes.
This item is configurable only when Fast Boot
is set to Enabled
or Ultra Fast
I think I might know what you're talking about. Its whereby you set the default boot device in BIOS and it *refuses* to boot from anything else. Had this issue, UEFI mobo would not boot from USB at any costs to reinstall windows when windows was already installed. So had to physically delete the OS drive from the boot entry list in the bios, make the USB the default and then it worked. And after windows was reinstalled, the USB drive was automatically removed from boot device options and the SSD re-added. I thought it was the weirdest thing, but this might just explain it. Cheers
You'd get around this in Win10 by holding shift+restart when you are restarting from within windows, then going into UEFI settings from there, but from Windows 7 you would be screwed afaik.
Will have to install Win7 in EFI mode.
Yes installing 7 in EFI mode is the best option. Before I upgraded to 10 I was running 7 Ultimate in UEFI mode and it was great.
I am a computer technician and I work out of my home.
I probably have a half-dozen computers. A few are running Windows 7 Home Premium, one has been set up to dual boot to Windows 7 Pro or Windows XP Pro and one has Windows 7 Pro and Windows 8.1...

I have a dual boot set up - Windows 7 Ultimate 64-bit on an SSD drive and Windows 8.1 on a second hard drive. I would like to upgrade Windows 8.1 to Windows 10 and keep the Windows 7 OS in tact.
Is this possible? Can I just go through the...
Here's the situation. I have a 17" laptop with two Win 7 drives set up with dual boot. One is a 128gb SSD with all my work software. (AutoCad, Rhino, etc) The other is a new 256 SSD with only the Win7 OS installed. Both use the same laptop...
I used the ISO (64bit) burnt to DVD, changed boot order to install and installed to a new 250GB HDD, setup was about 15 mins and the dual boot works great, Windows 10 installed fine and Windows 7 has not been affected and runs as normal :D
