Help installing Windows 10 UEFI??

[asand1]

I installed Windows 10 on my new system a few months ago (ECS A960MV-M)following the upgrade path for XP/Vista users. Currently it is installed with MBR partitions in a BIOS setup. I would like to reinstall with UEFI (GPT). Seems that downloading the ISO and using RUFUS is the way to go.

What is not clear to me is, do I need to change any settings in BIOS prior to the change. Should I turn my overclocks back to stock? Should I change the HDD to UEFI in BIOS? Anything else?

In my experience, when upgrading, UEFI completely replaced BIOS and had it's own default settings. However, I upgraded directly from Win 7 without messing with any partitions until after the upgrade. I would do some googling if no one on here comes up with any other info. Good luck. I don't know if the overclocks would stick or not, but if you had planned on leaving them anyway, I wouldn't worry about reverting the settings.

Do you plan on going to a dual boot setup? In my past experience mbr or uefi doesn't make any performance difference in a single or dual boot config

Well I've already switched to AHCI, and boot time is down to 24 seconds, but I would like to have the graphical interface with mouse input. I suppose at this point its not important. I only have a 250G HDD. At this point I'm just trying to optimize the hard pats I have.

I set up a quintuple-boot system (XP,7,8,10 and Mint 14 XFCE) on a circa 2007 pc i got for free using MBR and didnt run into any trouble

There is all kind of theoretical advantages to uefi

but I've found in real life it just tends to complicate things.

My laptop that is running Win 10, which is UEFI, starts up within 30 seconds if not half that and I'm already at the log in with minimal lag if any once I log in. I'm set up to dual boot with Linux Ubuntu and this hasn't changed anything. Ubuntu has a 230gb partition and Windows uses the other 470 gb on this 700gb HDD. UEFI has it to where the computer directly boots instead of loading BIOS type information. You no longer get the option to access BIOS or interrupt startup. To access UEFI settings you have to hold down the shift key while pressing restart from the menu and it will give you options and then you find your way to UEFI settings and it will reboot the computer into that menu. With Ubuntu installed It loads GRUB immediately and asks me to choose which OS to boot, but this hasn't taken away from how quickly the computer will be up and running.
