How to recover windows 11 missing from BIOS on asus laptop?

Hello everyone. I will give a brief summary on my issue.

I installed the linux mint 21.2 cinnamon iso to a flash drive. (1TB)
I later attempted to install it along side windows 11, It said i did not have enough space, I then aborted the installation and unplugged the usb.
I booted back into windows 11 and attempted to sign in, I'm not 100% sure of what it said but I remember it being about a network connection.
I restarted the laptop, and came face to face with a BSOD. Error 0x74: Bad_system_config_info.
I waited a while and turned back on the laptop, It now boots straight to BIOS, no windows boot manager in sight.
Now if i power on the laptop it will instantly boot straight to the bios, unless I plugin the usb with the linux iso on it.
I've looked around a bit and I've seen a few people talking about either a UEFI repair, or it may be something with the registry.
I haven't found any 100% definetive answer to my problem yet.
It doesn't sound like a big problem considering the laptop boots perfectly fine, it just boots straight to bios without the usb being plugged in.

Is there anything I should include? Please let me know if there are any simple fixes to this, thank you.

    Hi, Y,

    Sorry to hear you're experiencing this issue.

    The incomplete installation of Windows 11 on the flash drive may have corrupted the EFI partition of your hard drive. You will need to create a bootable USB with the Windows installation and repair the EFI partition.

    1-Create a USB device with an installation image.

    You can create using the media creation tool, download it on this link.

    https://www.microsoft.com/software-download/win...

    2-Enter on BIOS/UEFI and change to boot from the USB device.

    3-On the installation screen click on "Repair your PC" in the left bottom

    4-Click on "Troubleshoot" and then the Advanced Options page will appear.

    5-Click on "Command Prompt".

    6-Run these commands.

    chkdsk D: /f /r (and press Enter)

    sfc /scannow (and press Enter)

    diskpart (and press Enter)

    sel disk 0 (and press Enter)

    list vol (and press Enter)

    7-Verify that the EFI partition (EPS) is using the FAT32 file system and assign a drive letter to it that is not already in use:

    sel vol <number of volume> (and press Enter)

    assign letter=Z: (and press Enter)

    exit (and press Enter)

    8-In order to repair the boot record:

    cd /d Z:\EFI\Microsoft\Boot\ (and press Enter)

    bootrec /FixBoot (and press Enter)

    ren BCD BCD.old (and press Enter)

    bcdboot c:\Windows /l en-us /s <boot letter>: All (and press Enter)

    (Note: The <boot letter> is replaced with the letter of the drive that you are booting from. (For example, C:, D:)

    9-When finished close the command prompt then click to return to the first screen

    10-Click to continue to normal boot

    Note for step 6: You need to change to the partition where Windows was installed by default the D:

    1-Type: D: and press enter

    2-After that run the command DIR

    3-This command will show the Windows folders like Users, Program files ... if these folders are not shown you need to change to another letter E:, F:, G...

    4-When you find the partition you can run these commands to repair it.

    I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.

    Hello again, I am finally back and I'm slowly starting to get more time to do this fix. I recently decided to test it out with the USB plugged in, all went well. And I seemed to nice after checking the drive, Linux mint might have installed it self partly over the drive, before being aborted. I'm starting to believe it may have installed it self over the efi and other boot files and wiped windows 11 away, but failed part-way because i aborted the installation. Is there anything I should include that may be of concern?

    sorry for the late reply, and also thank you. I will be trying this out whenever I find the time to. Are there any videos that will be a good walk through to verify I don't mess anything up?
