I am trying to dual boot Vista and Windows Server 2008 (WS0. I install Disk Director 10 (DD) and Operating System Selector (OSS) in Vista. OSS recognizes fine Vista. When I install WS08, OSS cannot recognize WS08 as a bootable choice. I see it and can manually set it as bootable in OSS but it still cannot recognize it as a choice to click on as I boot up. It appears that WS08 installs its own booting utility and deactivates OSS. When I get OSS activated again (and I'm not sure exactly how I do it), I see only Vista. Clicking on Vista, then brings up the WS08 booting utility which allows me to choose between Vista and WS08. This seems to work okay although it is awkward because I lack full control over it. I go into OSS in Vista and try to make it work. Then, I can't boot into WS08 as computer keeps resetting and refuses to reboot. It says it is missing autocheck file as it tries to boot WS08. I, then, have to reinstall WS08. At any rate, this is very frustating. Does anyone have any suggestions?
