Thread: dd iso9660

i attempting create iso file of windows recovery partition. not have optical drive handy, have been using dd command in various combinations no success.

basic command have tried is:

code:

sudo dd if=/dev/sda3 of=recovery_partition.iso bs=2048

when attempting open archive manager, receive , error stating iso not formatted in iso9660. when attempting use file in virtualbox, receive error stating no bootable media found.

have tried:

code:

sudo dd if=/dev/sda3 of=recovery_partition.img bs=2048  ccd2iso recovery_partition.img recovery_partition.iso

this results in:

code:

cannot open source file reading!

finally, using:

code:

sudo dd if=/dev/sda3 of=recovery_partition.img bs=2048  vboxmanage convertdd recovery_partition.iso recovery_partition.iso

gives disk error, press key restart.
