Have you tried qemu boot_sect_hello.bin?

amiyadav commented 3 years ago

yeah alone qemu is not working instead I have to use qemu-system-x86_64 boot_sect_hello.bin which gives me Not a bootable disk.

I am doing this on MAC

What command are you using to build the boot_sect_hello.bin file?

What was the output, if any?

@amiyadav Can you place the file boot_sect_hello.bin and the command sequence in a text file and send it across? I can run it on my system (windows/Ubuntu) and confirm the error. If possible, can also get in a google meet to see and debug the issue on your system

You appear to be entering the commands correctly, so it is probably a boot sector issue. Can you please provide source to it?
