UEFI and performance

post #1 of 3
Thread Starter 
Hi Gents,

In the spirit of performance I was wondering if there are any advantages of UEFI? I know the ability to support a larger bootable HDD and the GUI advancements ,but what about hardware stability?
Would UEFI be more stable at the driver level for, lets say, my GTX780? And by the way it is for Windows 8.1 on the machine in my sig. Thanks!

I'm no expert but I can offer some insight. Firstly, I highly doubt that it has any implications for the stability of driver-level operation. The only impact it should have is on the disk's partition table and boot operations. It is supposed to be fast and flexible as it does away with the need for a conventional boot loader and master boot record. Ultimately, your system may boot a second faster or so. It also benefits from the use of the more-modern GUID partition table (GPT) which also offers more flexibility. Note that the Windows installer does a less-than-stellar job at creating these tables and, if you strive for true stability and perfection, you should create your own table using such Linux tools as gdisk.

I have heard of and experienced, first-hand, rather poor implementations of the UEFI bios. My Lenovo laptop, for example, lacks a method to switch between UEFI and compatibility modes however, was inexplicably shipped with a BIOS partition table. Upon learning how to modify the Windows 7 installation disc to support UEFI by default, I did a fresh re-installation with the new method. Shockingly, after this was done, everything worked perfectly fine but I could not access the BIOS itself using any method. Luckily, full functionality was restored after re-flashing the BIOS. With Windows 8 defaulting to UEFI, other Lenovo customers have experienced similar issues with losing BIOS functionality after clean system installs. I had no such issue on my desktop, however.

First off, thanks for the reply!
I never even knew there was an option for UEFI until recently when I added another SSD. Turns out windows 8.1 likes to corrupt both drives when you just plug it in and no assign the active drive... Never had that problem with a HDD mad.gif...
I might have to look into gdisk and what options are available in the future. As for now my SSD's aren't quite at the 2.1Tb mark so I guess I can wait. I was hoping there was some driver level commands that could be handled better once in Windows but I guess that was wishful thinking.
