consider these circumstances: c:\250GB holds 32-Vista. I lately integrated d:\500GB, on which i want to install unix and ubuntu. dual booting seems risky -- i want to avoid reinstalling vista, and i want to avoid winding up with a $1200 paperweight. acronis has suggested that i use disk director suite 10.0. what is the relation between virtual machine and a bootloader? do the 2 concepts synergize? does one render the other a redundancy?
