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. -- W |

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. -- W |

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. |

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 |

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. I'm asking a much more general question: how does Windows 7 see a boot device, and how do you transfer a disk image from one computer to another so 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. -- W |

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.

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. -- W |
