Almost, except for the typo when applying. You're applying both images to the C:\ You can actually save both partitions in one .wim file with the /append function. imagex /capture c: g:\Dual-Boot.wim "Windows Vista" imagex /append d: g:\Dual-Boot.wim "Windows XP" then to apply it imagex /apply g:\Dual-Boot.wim 1 c: imagex /apply g:\Dual-Boot.wim 2 d: Yes, you should still get the Vista boot loader like before. Don't take my word for it though, find a test machine and try it out.
