Default UEFI Support in Windows 7?

Does Windows 7 support the need UEFI replacement for BIOS? If yes, does
this require 64-bit Windows 7? Does it require the system partition and
boot partition to both be on a GPT disk?

I have a Windows 7 Ultimate 64-bit boot partition working on an old Dell
computer. That computer's BIOS says nothing about UEFI. When I try to
copy over the image of the system partition and boot partition to a a Dell
T7600 system - which DOES offer UEFI boot devices as an option - and try to
boot in legacy mode, I get a message that I am trying to boot a UEFI device
in legacy mode. Unfortunately, that device does NOT show up in the list of
boot devices. When I select the device 0 on the boot controller, I get a
message that the partition cannot be booted (without any details).

If I go into the Dell T7600 setup and configure it to use UEFI, that is more
confusion. If I try to add a UEFI device, it tells me "No file system".
If I simply enable UEFI without adding a boot device, it finds nothing on
startup.

So at the end of the day, I have an exact image copy of a bootable WIndows 7
64-bit OS, and I cannot get it to boot in either legacy mode or in UEFI
mode. Since I have no experience with UEFI, I am just lost here.

P.S., I was copying over the Windows disk image just to bootstrap install
process, and I was going to relicense the OS once it booted.

You should be able to find a fair amount of specifics on Win7 and UEFI
in the following articles

http://technet.microsoft.com/en-us/l...01(WS.10).aspx

https://blogs.technet.com/b/askcore/...-computer.aspx

http://www.sevenforums.com/installat...therboard.html

Afaik....you need to boot the Win7 DVD in UEFI mode to install Win7 in
UEFI mode in order for it to run. As long as your system supports UEFI
the installation will handle the required partitioning as noted in the
first article (technet.../library/..)above.

I guess if we are going to bother with UEFI at all we should probably just
use Windows 8 64-bit, since that has much better support for UEFI,
particularly at run-time?

Back to my original question, what is the correct procedure for copying over
a Windows 7 mirror disk image to a new machine? You copy the 100 MB system
partition and then the boot partition, on an MBR disk, and then mark the
system partition as Active?

The above is what I am doing and the new system refuses to see this as a
bootable disk. It's not that it starts booting and fails to load some
essential driver. It's that it never starts to boot at all, and refuses to
see the disk as a bootable disk.

I can't get that partition seen by the one-time boot menu as a UEFI boot
disk. But when I boot in legacy mode the system complains that this is a
UEFI disk.

The UEFI features in my Dell T7600 UEFI / BIOS are horrific. It looks like
some kind of engineering experiment, far far far from being mature or usable
software. I don't understand at this point how to get the new system to
see the old install.

Since those are Dell computers which usually have preinstalled Windows(OEM)
tied to BIOS, I would be very surprised if the original system image worked
on the new Dell unless they were identical which is isn't the case.

FWIW, I have installed Windows 7, both X64 and X32, in systems without UEFI..

I also got hands on with a Dell Inspiron with Windows 8.1, and set up with UEFI. If you push the F12 key, you also get an option to revert back to a legacy BIOS, which I needed to do to use my software to remove the login password. Once set back to the legacy BIOS, the system will not boot properly unless you push F12 and select the drive formatted per the UEFI standard.

I hope this addresses your concerns... Ben Myers

that the new computer will at least *TRY* to boot from the system.

I agree the device drivers probably won't match up. You probably would need
to insert some new device drivers during the startup process to just avoid a
blue screen. That's not the problem I'm trying to solve now.

And in my current situation I am trying to use a retail license - not OEM -
on both source and target systems. People use disk images to install a
base layer of OS and applications all the time. It can be done legally.

Install using a 64 bit Win7 DVD if UEFI mode is your end objective.

If its an OEM image, its tied to the Bios of the original machine.

I wasn't talking about legality. These machine usually have OS tied to
BIOS. Since yours is retail it's not tied to BIOS so it might work.

In the XP days if you wanted to go from IDE to AHCI, it needed severe
hacks if you didn't want to reinstall; maybe it's a similar process to go
UEFI, I don't know.

Yes, of course, there no real difference between the UEFI BIOS and the
regular BIOS, except support for larger hard disks and a few other
things. UEFI maintains a compatibility layer with BIOS. The UEFI BIOS is
what loads the OS, not the other way around, so you should conceivably
be able to load up an ancient DOS disk through UEFI.

I have just recently done such a conversion. I went from a motheboard
with a traditional BIOS (Asus M4A785-M) to one with a UEFI BIOS
(Gigabyte 990FXA-UD5). Didn't have to reinstall the OS or anything.
Didn't have to change the disks over to the GPT partition either,
everything remained on MBR. Now I did also recently buy a 3TB drive
which requires GPT partitions to work, but I'm not booting from it
though, it's just a standard data disk.

Yeah, if you want to boot from a disk formatted with GPT partitions,
then the steps for making it bootable is more involved. Here's the

Thanks for information here. The support article is about how to create a
GPT boot mirror. That's not my issue.

My problem is I have an MBR disk with a bootable Windows 7 64-bit OS on it.
I take that disk and image copy the System Partition and the Boot Partition
to a new device. I mark System Partition as Active. When I attempt to
boot that from the new computer, it fails to see a bootable partition. I
just don't get it. I would totally understand it starting to boot and
then failing on some device driver mismatch. That's not this case. It
never starts to boot. It refuses to see the device as a valid boot image,
no matter whether I start in BIOS or UEFI modes.
