Is full partition encryption the only sure way to make Ubuntu safe from external access?

encryption

(By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine)

A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again).

However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)...

I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both.

Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap..

Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition?

PS.. Is encryption a suitable solution?
