Windows 10: Have a Real Problem With Changing the BOOT from Legacy to UEFI

Hi

I'd appreciate some help with changing how my machine boots.

Soon I hope to install Windows 10 Pro onto a new hard drive.

The existing HD with Windows 7 Home Premium 64-bit
(that I still need for a good 9 months yet) will be used via external USB adaptor.

The new hard drive to install Win10 on is a WD Blue 2.5" 2TB.

I've since read that the 2TB will not be fully used if the BIOS is using Legacy.
Not only that, but you lose data because of Legacy.

Also I would like to take advantage of more Partitions using UEFI.

BUT HERE'S MY PROBLEM

On my Motherboard - Manufacturer ASUSTeK Computer Inc.
Model N73SV (CPU 1)
Version 1.0

BIOS - Brand American Megatrends Inc.
Version N73SV.305
Date 18/05/2011

That I reach using F2 - IT SHOWS THAT: UEFI is disabled.

I thought that I could just Enable it - BUT I haven't tried that yet because I'm not ready to install Win10

And then a few weeks ago I read this - the only way to physically CHANGE/ENABLE "UEFI"
is to remove the CMOS battery.

So I brought a new battery and also new RAM.

Then I discovered that this machine is a real pig to reach the motherboard.

After I found out how to open it with no visible screws, I reached the RAM and Hard Drive bays
using YouTube help.

But then watching other YouTubes - "the only way to reach the Motherboard proper" say to clean the fan
or change the battery, that are simple jobs on a PC Tower - it means I have to somehow split the
ASUS N73SV Notebook casing.

But it gets worse - in fact it seems you have to split the monitor casing as well.

Can't be completely sure about splitting the monitor casing, because these videos are run at such a pace
it is difficult to know for sure.

So before I attempt to split the casing etc, is there any other way to physically TURN OFF/RESET THE MOTHERBOARD
without "shorting two point on the MB with say a paperclip or removing the battery?

So that I can change it, so it Boots using UEFI ???


Just another problem if I manage to change how it Boots.

Earlier I mentioned how I'm going to still use Windows 7 with an external USB adaptor.

BUT WHAT HAPPENS WITH BOOTING THIS DRIVE IF I DO MANAGE TO CHANGE TO UEFI ?

Because wont the Legacy Boot be embedded at the
start of the "now external drive" ?

While I'm here, a few weeks ago I moved from Seven Forums that I always found it
easy to include a Thank You or SOLVED.

But with Ten Forums I couldn't find how to do that.

Many thanks in advance.

UEFI vs Legacy boot mode

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.

 

How to change a legacy Boot W10 diskt to use UEFI Boot

Hi all,

I would like to modernize my well running W10 by changing the boot process to UEFI (Reason: Using NVmE SSDs or GPT sized disk). Because the system has many well configured apps used day by day a clean install would be the least favorable choice.

So my questions are:

• Is it possible to patch a fully installed and featured W10 from legacy boot to UEFI boot? And how?
• If possible: does a patched system needs a new activation (Its a migrated W10 from W7)?

BTW: I have already read lots of post dealing with UEFI. But I didn't find any usable answer yet.

TIA and best regards.

 

UEFI vs Legacy boot mode

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 *Oh Well hwell:
