Insert Boot Sector

Recommended Posts

I was looking for a way to directly insert a boot sector into an image. Every piece of software that I've come across so far (magic ISO, ultra ISO...) also re-saves/re-structures the remaining content of the disc. Is it possible to simply directly insert a boot image? I can happily use dd if required.

Thanks!!

I don't understand clearly.

Do you like to insert new data?

A old sector does exist and you like to overwrite this sector?

Use a hex editor or dd.

I'm using dd.

$ dd count=1 bs=2048 skip=625 if=C:/temp/image.iso of=bootimage.img

$ dd count=1 bs=2048 seek=625 conv=notrunc if=bootimage.img of=C:/temp/image.iso
