Another Convert MBR to GPT question

I run my own business and needed to upgrade my hardware, so a built a new machine.

This is the mobo:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130779

The new machine uses UEFI and the old machine has an MBR HD in it.  I used Veeam to create an image and transferred it to the new machine.
NOTE: The new one has a RAID5 array set up on it.
Veeam warned about an MBR image going to a UEFI system.  It was right.  It won't boot.

Secure boot is turned off in the BIOS, but I don't see an option to turn UEFI off on this mobo.

I tried booting from a Windows 10 CD and run gptgen.exe, but got an error message:
"The subsystem needed to support the image is not present."

Diskpart requires that the Volume be deleted.  I am desperately trying to avoid data loss!

Have you tried enabling Compatibility Support Mode in the BIOS?

I don't know where that is in the BIOS.  I'll search for it.  But I don't think it is there.

How can a software RAID be more efficient than hardware?

You have convinced me not to use RAID5.  Thanks.  However, RAID1 (mirror set) would be my next choice.  My mobo does not support RAID6.

Are you saying that even RAID1 should be done at the OS level?

I'm running Windows 10.
Yes, RAID 1 should be done with OS built-in RAID. The RAID controllers that are built into mainboards are just cheap fake-RAID controllers which are nothing but crap. The RAID you can do via the OS on the other hand is very efficient. For example, it reads data off the 2 disks simultaneously which even most of the expensive, real hardware RAID controllers can't do. So reading from RAID 1 is a lot faster. Also, other than with RAID controllers, you don't necessarily need enterprise class disks. Particularly RAID 1 should be done at OS level.

But you will need Windows 10 Pro. The home version doesn't support RAID, but it does support something similar, storage spaces.
>How can a software RAID be more efficient than hardware?

It's not real hardware raid.
Most real hardware raid controllers have a disk co processor and cache.
Yours does not.

And as an extra fyi ,unless you are using raid certified disks (WD RE or Seagate ES),hardware raid controllers can have issues with good desk top grade disks timing out and being marked as bad.
Some new BIOSes do not have an option to disable the UEFI. Looks like the hardware providers are pressing us to move to new hardware. Got this recently on Panasonic CF54 laptop.

What you can try is to run Windows installation on this machine - after the steps where it says - copying files - interrupt it.
Then restore the system partition by overwriting C: partition on the drive.
Check if it boots. There could be UEFI fix needed.
I have become more acquainted with the BIOS setup and found that I can boot from an MBR disk in legacy mode.

I have learned a lot from this question thanks to you all!
Can you recommend a decent controller that can handle a RAID6 array?
