    Windows 7 doesn't support GOP and needs INT10 emulation from the CSM. Gen3 UEFI lack the INT10 emulations, even if they still offer CSM.
    I could install Windows 7 in MBR mode with CSM enabled, but not UEFI, it freezes at the animated flag.

    I have gotten a Packardbell easynote ente69ap. I hate any of the windows version higher than 7. As I understand it the its gen 3 and it wont allow win7 to boot even from a custom uefi dvd image.
    So around all the above arguments and what not. Why not just remove the HDD from the laptop add it to a normal pc format s tart the win7 install and then on first reboot shut down and put the HDD back into the laptop and let the install continue from there?

    There by skipping the whole UEFI issue.

    Every time you start your pc(desktop/laptop), something has to boot. Be it a live OS from portable media or a host OS on your internal drive.
    By performing the voodoo ritual that you described, you're not skipping anything, you're just delaying the disappointment of seeing windows 7 hang after uefi firmware passes on the torch.

    Any form of a CSM is always needed.

    Lately we have seen a few endless win 7 on UEFI discussions:thinking:

    Why don't you just read the first page? It's been discussed.

    The problem is that some systems automatically activate certain CSM features (INT10h emulation) when they encounter a Windows 7 booting in UEFI. That'll happen even if CSM is set to off and thus confuse users.

    1. Any UEFI up to Generation 2 (with CSM) and CSM activated - Windows 7 will boot in UEFI mode.
    2. Any UEFI up to Generation 2 (with CSM) and CSM disabled in BIOS Setup - Windows 7 might boot in UEFI mode if the system auto-enables INT10h.
    3. Any UEFI Generation 3 and up (without any CSM) - Windows 7 will NOT boot in UEFI mode and freeze at the animated boot logo.

    Windows 7 will always boot in Legacy (non-UEFI) mode if the system still contains that switch.

    No, it's not. I did ask you to read the first page. (edit)While what Carlos Detweiller says is true(/edit), the tutorial is applicable in certain scenarios.

    Note that UEFI only supporting FAT32 is a big misinterpretation of the specs. For all I know, the UEFI specs say that an UEFI implementation has to support at least FAT32. It can support other filesystems, but only FAT32 is mandatory. UEFI:NTFS is reality with the correct FS driver.

    FAT32 support is required for getting the certification. UEFI will boot everything you throw at it, as long as you provide a fs driver that tells it how to handle the file system.

    The big problem is not UEFI, but Secure Boot. Getting a fs driver signed is where the "fun" starts...

    As You can see, check path: (look inside /efi/boot/ folder)
    Code:
    /efi/boot/bootx64.efi

    I never use rufus, i just format the USB FAT32 and extract the iso to it's root, all works fine, in UEFI (with or without CSM enabled) or Legacy BIOS.

    Then go to the rufus thread, and ask there...

    Haven't you learned from last time? You argued about something completely unrelated to the thread, you provided questionable "evidence" at best... dude, point still stands - unmodified windows 7 cannot boot pure UEFI. Tutorials like this one or @Atak_Snajpera 's tool aren't meant to solve that problem. Now that you finally found the right thread to ask your question, you're just coming back for more arguing? Anybody, who wants to chop-chop safe mode to make windows 7 bootable on modern hardware, can go right ahead. That's not a modification I'm willing to perform considering the results. I'd rather disable/strip minor OS components while retaining core OS functionality - LTSC 2019. Most I'm willing to do(and I am doing it for other people) is integrate updates/runtimes/some drivers and make an AIO.

    Would be nice if tryhards kept tryharding without assuming to be tHe EnLiGhTeNeD oNeS around. No one's stopping you.

    I think it has to be clear that by enabling UEFI-CSM, we will be able to boot , install & work Win 7 in UEFI + GPT , It will be fully functional as UEFI, but theortically / logically its not pure UEFI!

    im not arguing :D you are letting off steam.
    im just happy there is a way to install windows 7 to class 3 uefi machines now, even though it's kinda CHOP CHOP like you said :) no ones fighting.. you just seem little tense :)
