BIOS won't see bootable USB/Only boot option is "Windows boot mngr "

cagdas said:

yes I did rufus and it formatted the usb to NTFS and I didnt change it probably its the right one

No. NTFS is Wrong. UEFI can only boot Fat32. It needs to be changed.

I didn't see mentioned but a lot of computers have a BIOS that doesn't support USB 3.0 ports [usually blue] or devices until after the Operating System has loaded. One has to make sure to use the USB 2.0 port [black] and in some cases a slightly older Thumb drive. I believe the MCT/Media Creation Tool reformats the Thumb drive as FAT32. I always use 8GB drives, 4GB frequently isn't enough and anything on the drive gets deleted in the process so using 16GB and larger is not necessary.

I am using the 2.0 usb port and my usb disk is 2.0 aswell but rufus reformatted to NTFS i do not know if thats a problem but ill try the asus manager thing rn

Modifying the bios settings is very likely unnecessary. I would try just re-creating the usb but format it with Fat32. That is almost definitely the problem.

If the computer has UEFI capabilities, it has to be at the very least not ancient. I would say it is safe to say that if it has UEFI, you can boot from USB devices on it. The bios will probably only display the USB option if it detects a bootable USB stick, but since there isn't one, it isn't listed.

How did you create the bootable USB is what I want to know. Did you use Rufus? As far as i know, rufus is the only tool able to create bootable USBs that can be detected by UEFI...

first it said that it wasnt compatible with the iso when i tried fat32 but now that i changed it to GPT its formatting

Yeah. If you are using UEFI and your rufus display looks like the picture that I posted in my first post, then you are good to go.

the computer has UEFI compability because the current OS thats running is UEFI but the bios doesnt show anything else than windows boot manager even when ı put a disc in the reader it just shows windows boot manager as a bootable device and doesnt let me add new boot options

Ok. Lets verify some information real quick. UEFI has nothing to do with the OS. UEFI is firmware that is meant to replace legacy BIOS. The only relation that it has to the OS is if the os can run using uefi (only windows 8+ can).

If your computer has UEFI capabilities, you would see a area in your bios settings that looks something like this:


You may also see references to "secure boot" and being able to turn it off or something similar. If you don't see any mention of UEFI or secure boot in your bios settings, your computer does NOT support it.
