i can use nasm alright.
along time ago i burned a small program on a usb drive using debug.exe i think
i've been searching for hours and i still dont know how to test my code
qemu was a fail(im using windows for ide)

can anyone tell me how to boot my code when the computer starts(without writing to hard drive). when it comes to floppy bootimages, usb boot images and iso boot images im completly lost. and no i dont have any bootimages just the output code for my .asm file

once i can test my code i'll be making my own operating system development enviornment
i been building code from the ground up since i was 10. im 23 now

Could you not slap GRUB on the USB drive, and do it that way? That's how I'm doing my OS at the moment. Then there's no need to faff with debug.exe, dd, or whatever your host OS uses, just copy/paste.

Also, with regards to booting, just set QEMU up to use the USB drive as a HDD.
