I forget where I hear it or if it was my own idea (the shame, I know, I know!) but... cant you have an unknown number of username/password pairs that decrypt/unpack the same chunk of data into different things? Say you have the same OS 51 times, as clean installs the data shouldn't have to be all that much larger than 1. You install some games on one, some office apps on the next, put some downloaded movies on the 3rd. You could give them "all" 50 passwords and they could never find OS nr 51. |

1. Each filesystem lives within an allocated area and knows not to overwrite its neighbors' data.
2. Some filesystems (the real ones) are privileged and know their actual allocated area. Others (the decoys) think they own areas of the storage volume that contain hidden data and therefore have the potential to overwrite the hidden filesystems if they are written to.
In the case of (1), you need to be able to explain why your computer has unallocated areas filled with pseudorandom data. That is never going to pass the plausibility test, imo.
In the case of (2), a lot of effort needs to be put into making the decoys look normal while not letting them overwrite the hidden data. There are a number of strategies you could use here that would work, but it will never be as convenient or simple as dual-booting and the more convenient you try to make it, the less innocent a hard drive will appear under close inspection.
