Testing on usb with real hardware

[feare56]

I am trying to boot my img image, that works in virtual machines, on a usb and gives me an error saying can not boot floppy Press a key to reboot. Is it because i am trying to boot a floppy image on a usb? What is the problem? I followed the brokenthorn series for the bootloader

How are you trying to write the floppy image to the USB? A Floppy image wont write to USB very well.

I recommend taking a look at the grub tool for writing to USB (think its called grub-mkrescue or simular), or looking at YUMI bootloader.

I have been using

Code: Select all

dd if=***.img of=/dev/sdb*

It looked like it had no problems copying it over

A MBR is not a VBR. You're not writing the entire stick.
