Windows 10: UEFI drive question?

Hi All,
Sorry but UEFI is all gobbledygook to me.
I have 4 internal hard drives:
500Gb SSD (C Drive)
2 x internal 1TB SATA drives, and I've kept my old 250Gb SSD which used to have my operating system on, inside my computer for backups.
I've disabled the 2 SATA drives, and my 250Gb SSD from the boot option, that's why you can't see them below.
Now, Iv'e just made a Macrium Reflect USB boot drive, and that's the only drive that is UEFI???
Should my main 500Gb SSD drive be UEFI as well???
Would it give me any performance improvements???
I haven't a clue!!!

Cannot convert SSD drive from legacy (MBR) to UEFI (GPT) because of the System-reserved partition

Maybe someone covered this earlier in the thread but a Legacy Windows install will not boot to a GPT configured drive. You need to use UEFI for that and UEFI will not boot to a MBR configured drive.

So, unless you have a UEFI capable system you need to stay with MBR for the Boot drive...

 

Cannot install windows 10 ISO on hard drive partition GPT or MBR!

Hi,

What type of problem are you having ?

If your machine came with Win 10 it is a UEFI machine and requires a GPT drive to install Win 10 on...

Your computer may not install to a UEFI Bios from a DVD...

You may need to hit Boot Options at the manufacturer's screen by hitting F2, F11, F12, ESC, Del, or whatever your machine uses...

You will want to look for your DVD or Flash Drive... They will probably be listed twice...

Once as normal, and again as a "UEFI DVD Drive" or whatever your drive is named, or "UEFI USB..." whatever your Flash Drive is named...

A Flash Drive needs to be made by the Create Media tool, preferably on the machine it is going to install to... If done on another machine, be sure to indicate it is for another machine... You may have problems if the other machine does not also have UEFI
Bios...

The deal with the flash drive is that it needs to be created differently for Legacy MBR and UEFI... UEFI requires the flash drive is formatted FAT32, and Legacy MBR requires that the flash drive is formatted as NTFS...

 

The only important thing is that your OS is in UEFI mode. None of the other drives does it really apply to as far as I know. That is the way I have my system set up. The OS is in UEFI Mode, everything else is a normal.

 

You can force macrium boot disk into Legacy boot by removing Bootmgr.efi and the EFI folder from the macrium Boot Media..

 

UEFI does not give a general performance boost. It does, however, make boot times faster and allows the OS to utilize very large hard disks, and boot from partitions that are anywhere on the drive.

UEFI also provides some interesting functionality for other OS functions. I would make your systems UEFI compatible, because the day will come when you want to use a 4TB drive and you will find it will have problems with BIOS installs.

 

It isn't UEFI, it is EFI. EFI has nothing to do with large drive sizes. It is GPT disk formatting of that permits for drives larger than 4TB.

Making your boot EFI does require you to have a GPT formatted systems disk. But there are other compatibility considerations to be able to boot EFI, for instance your graphics card BIOS must support GOP/EFI or your system won't boot fully EFI.

 

I thought EFI was just what they called it before it was Unified (UEFI)? Aren't they then the same thing (though I think there are newer versions, like 2.0 or something)?
