How do I convert a .bin file into a .iso file for usb use

I have a .bin file that I would like to convert to an iso to burn to a usb. The .bin file is clearly bootable; The output of

file os-image.bin

../os-image.bin: DOS/MBR boot sector

and I can boot it in qemu.

but when I convert it to iso:

genisoimage -o drip.iso os-image.bin

or bchunck or PowerISO or bin2iso

the output of the file command is:

drip.iso: ISO 9660 CD-ROM filesystem data 'CDROM'

and rufus won't write it to usb, and qemu won't boot.

Also, when I write the bin to the usb with rufus, it won't boot on a regular computer.

So I have figured out the issue.

My image that I was using for writing wasn't for UEFI so it didn't want to boot on newer PCs.
