How do I mount an entire hard drive image?

I have a drive image that I need to mount, boot sector and all.
The common method of mount -o loop, -t ntfs offset=number image.img /mnt/drive doesn't apply to me,
I need to do what it tells me I'm trying to do when I try mount -o loop, image.img /mnt/drive

"Maybe the wrong device is used? Or the whole disk instead of a partition"

exactly this though, whole disk. I don't want to mount a partition, I need to be able to access the whole drive including boot sector.

any ideas?

I know this is possible in Windows, so I assume it must be in Linux
