I formatted a USB to a bootable usb with windows 10. Now when I enter BIOS mode, this bootable usb is not recognized. First, I tried the fat32 type, but the .iso file from windows is to large to be copied on the usb drive. Then, I tried the exFat type and the NTFS type, but they are both not recognized when I want to choose them as the prior boot option. I tried both enabling and disabling legacy mode, and I disabled secure boot and fast boot. I could not find anything about CSM in my boot menu (asus rog strix). Does anyone know how I can fix this?

For UEFI mode that is the only one that should be used in any modern UEFI hardware, all you need to do it to extract the ISO (with 7Zip) to a NTFS formatted USB dongle of at least 8GB.
For better results download and create the installation media directly using the automated Windows Media creation tool in a Windows machine. With some effort and know how it can be done in a Windows VM running in any host OS.
Other than that, in Ubuntu, MKUSB or WoeUSB have been used successfully even with the new, overweight, non-standard Microsoft ISOs.
