My initlal reading was that you wanted to take a dual boot windows/linux system then take that direct windows instance and bring it under xen - effectively a sort of physical to virtual but on the same system... That is *feasible* on an appropriate system with some care and probably a windows recovery console... But if you are asking how to take a dual boot system and have that windows instance available to Xen but still also dual boot capable.... well again with a windows recovery console to aid the switch potentially possible (XP/vista/7/2003/2008?) but due to HAL differences (and potentially activation depending on version as well) then it most likely won't work (easily)... so finding a guide for that is unlikely... and from memory you'll mostly find posts with dead ends of how it fails for windows.... however if you are determined to try you *might* find some success depending on windows version to have multiple hardware profiles and that *might* work.... It will, however, be potentially very fragile. TL;DR: Maybe possible with some careful choosing of hardware (both real and virtual) whilst being careful to never mount the same partitions on the disk at the same time and with some hacking of windows for hardware, drivers, etc and dependant on windows version with regards to how it will behave for activation with changing hardware...
