    Hello. I have Asus X550CC with modified BIOS (SLIC 2.1) from this forum. I need install Win 7 on this. But BIOS in it don't run in Legacy mode and in UEFI mode don't boot from USB and from DVD. I need set BIOS on legacy. Previously OS is Win 10. I'm formated HDD on MBR mode. Any solution on this? Thank you.

    I used a Rufus. I tried all three options, but it didn't help for my. I tried Ubuntu from unetboot.in, but it don't helped too.

    OK. I do it at the moment. Yes, I use USB2 port.
    Is any chance, when I flash any older version, that it will work?

    Don't you need a modded Win 7 ISO to include UEFI?

    Didn't think 7 worked with UEFI natively?

    Can I create the flash disc first and then insert the folder, or first I must edit *iso and then create it from Rufus?

    OK, I do it. And Rufus set to GPT, MBR or CSM?

    Run Rufus then
    1. Enable dual UEFI+BIOS boot by using the Alt-E keys (keyboard)
    2. Select iso file
    3. Select target UFD
    4. Click Start
    Note: leave rest of options alone.

    Or

    1. Burn a DVD.

    Enter into machine BIOS/UEFI and select compatibility mode, CSM. CSM must be enabled for UEFI to work with Windows 7.
    FYI Windows 7 quasi supports UEFI mode.

    Booting from UFD:
    After power up the machine press the appropriate key to bring up Boot Device Selector or Boot Menu or whatever is called in your PC.
    You must choose the item which says UEFI in it.

    If you have w10 already installed why mess with setup ?

    Just deploy deploy w7 on a vhd or on a separate partition, using dism, imagex or gimagex, add the w7 item to your current bootloader, and you're done in literally 5 minutes.

    Sorry, but it didn´t work. I insert UFD into USB2, in boot menu I select UEFI: Kingston (it´s my UFD), then result is:

    Secure Boot Violation
    Invalid signature detected. Check Secure Boot Policy in Setup

    My next attempt:

    I insert DVD with W10, boot from it, format and erase any HDD partiton. Then I remove DVD and select "repair computer", run CMD, insert UFD with W7 UEFI, then I type "C:/sources\setup.exe
    Wow, W7 has installing, I´m happy. BUT to first restart. After first restart, the same error (Secure Boot Violation....)

    Is any chance to lock BIOS back? I´m unlocked it to SLIC 2.1 with utility from this forum:
    https://forums.mydigitallife.net/th...uests/page4964?p=865741&viewfull=1#post865741

    I think before that there was the possibility legacy in BIOS. But I´m not sure.......

    It made me sad.....Please help me......

    well that sux!
    I see your using the v.300 bios, I wonder (not that I could recommend it) what the original/earlier bios had in it?
    If it's not possible to disable the secure boot option, you might be stuck using Windows 8.1 or 10
