I just found out I'm running at "Legacy" boot mode.
Are there any downsides running my Skylake system in "Legacy" boot mode?

I don't really want to reinstall windows.
Also I have no problems with my SSD, speeds are as they should be.

Just booting up my system takes some time, maybe it just would be faster booting with UEFI?
My Asus Gaming laptop is booting up faster.
If thats the main difference :ohwell:

The only real differences I've noticed are that UEFI mode boots faster and if you have your Motherboard's boot logo enabled, then it replaces the Blue Windows logo when Windows is booting. So you see the motherboard's boot logo the entire time, with the little white spinning dots under it when Windows is loading.

You're all good. With UEFI boot partitions can be over 2TB, but that means reformatting drive to GPT.........prob not something you'd want to do....(or me :))
You aren't missing out on much., as mentioned above. Maybe Secure Boot......bleh :p

It's just the boot time, not so fast, my asus g750 is booting faster :ohwell:
Ok so besides secure boot, and a bit slower boot, I don't miss out on anything else then.:)

Thanks.

I use legacy on my g752vy, just because I don't trust M$ to let him mess with my uefi/bios...

Did not check that before I installed windows, I would have expected that the default BIOS setting of my motherboard would be UEFI boot mode,
so it wasn't , I just found a few days ago... Oh well it works fine, I'm happy with it. :D

Benchmark Scores Don't know any benchmark. It runs good enough for me.
I recommend you stick with legacy install instead to avoid any compatibility problem hardware or software. Uefi have the speed advantage for boot up but I don't find it to be a good trade-off for the compatibility problems that appeared. Secure boot for uefi is a pain if you decide to install multiple os as the other os is "locked" out. I used uefi for my previous install it is a lengthy install selecting the correct bios setting without borking the install. I'll move to uefi if I don't have a need for multiple os or legacy things. So far I seem to need it.

I also recommend legacy mode. UEFI has to tight integration with the OS which is exactly the problem. There was a case where UEFI installed bloatware on fresh Windows installations automatically. It shouldn't be supposed to be able to do that unless the firmware was open-source.

My GPU has a physical bios switch on it. It was set to Compatability mode from the maker- i switched it to uefi no issues, I use Win 7 so secureboot is not an option

Switching to UEFI bios on GPU does not enable UEFI mode if motherboard is set CSM = On. Setting CSM = Off in my experience causes Windows 7 issues, even if installed as UEFI mode with GPT partition on storage device.

Plus with UEFI it uses the BIOS Image via replacing the Windows Boot Logo :) (at least with my MB)

Yep, UEFI mode with Win 10 loading I get the Asus logo.

IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

If system is booting in legacy mode - you get Windows Logo.
If system is booting in UEFI mode - you get OEM logo.

Above also applies to Win 8 but not Win 7.

With win.7 also? Nice! But I'm sure you can do a hack to replace the image in the registry
