I'm trying to copy entire iso including mbr into a usb device, the iso is an output of kernel compilation with
make isoimage, the problem is it won't boot from the usb.
fdisk on the USB device
$ sudo fdisk -l /dev/sdc Disk /dev/sdc: 15.4 GB, 15376000000 bytes, 30031250 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
$ file -s linux.iso linux.iso: # ISO 9660 CD-ROM filesystem data 'CDROM' (bootable)
dd command i used in order to copy the ISO contents into the USB
$ dd if=linux.iso of=/dev/sdc bs=1MB
