    So I got my Origin PC Millennium recently. They also gave me a Windows 7 DVD (ORIGIN PC Edition) which has all the modified logon backgrounds and such relevant to Origin PC

    The problem is, now I want to make a clean installation in UEFI mode but when inserting the disc, the BIOS on my ASUS X-99 Deluxe motherboard only gives me the normal boot option not the UEFI option.

    If I insert my origin Windows 7 Pro disc that I had bought in the past, I do get the UEFI boot option.

    So as a workaround I though ok let me extract the image of that ORIGIN PC Windows 7 Disc and copy it to a USB using Rufus. In RUFUS I ensured to make it UEFI bootable for GPT partitions but when I boot off it and manually guide it to where the driver for my Intel 750 PCIe SSD is located and initialize the partition as a GPT partition, I get a message saying that I cannot install it on this partition because it is not bootable make sure the controller is enabled in the BIOS

    So I guess that ISO is missing part of the UEFI boot or something? If I boot off that DVD in normal mode (not UEFI) I am able to install provided that I initialize the disc as MBR but that's not what I want, I want to install it in UEFI mode / GPT partition the same way they shipped the PC to me.

    How in the world were they able to install in UEFI mode / GPT partition from that disc?

    any ideas?

    Is there a way to make that ISO that I extracted properly UEFI bootable?

    I knew this would be the first comment :rolleyes:

    The Windows 7 section is dead and noone visits that subforum

    What does putting the USB drive in slot 2 and not 3 have to do with anything???????:rolleyes:

    Okay. Well for that to happen. You have to switch to legacy boot in the BIOS. Then you boot off that media.

    Then it's a matter of entering a couple of quick commands to restore UEFI after you finish the install bud :D

    Since I have a Windows 7 Pro (System Builders Edition) from Microsoft that IS UEFI bootable, can I not delete some folders off that ISO and replace them with the ones from the ORIGIN PC ones then burn the disc again? wouldn't that be UEFI bootable since the original MS disc was UEFI bootable and keep the ORIGIN PC Windows 7 edition in there?

    Which files shall I copy from the Origin PC onto that Windows 7 DVD and which files I shouldn't touch?

    But the problem is, if I don't install it in UEFI mode from the start, then I am forced to initialize the disc as MBR not GPT thus defeating the whole idea of UEFI. I don't know how in the world did they install it in UEFI mode / GPT partition off that disc.

    I don't know about that. I've never messed with the stuff in the ISO to make that happen

    But I used a program called gptgen to switch back to UEFI after I finished the install :)

    You need to get a win8/8.1/10 ISO, copy the efi folder to the win7 ISO and save to new ISO.

    Note that win7 only support X64 in efi. :D

    Gpt is for drives larger than 2gigs, and accomodates many partitions. Do you boot with a drive larger than that ?? and uefi works for a 64bit os not a 32 bit ...

    GPT also takes 1 sec less to initialize during boot up which is why I want it to be in GPT, the same way my system was shipped.

    Off topic, but is the bundled Windows OEM:SLP licensed?
