I've just successfully set XBMC as my standarddashboard by the way you mentioned here:

If you don't have E:\Dash\ then you didn't use Kingroach!
This is the safest way. Install XBMC as an application (in \Apps\XBMC\) and get it working as an application from your current dash.
Install the XBMC shortcut (SHORTCUT by TEAM XBMC) and its cfg file in a temporary directory, and edit the config file to point to your XBMC installation. Make sure that it launches XBMC when you select it.
Then the difficult bit - you have to find the location and name of the current dashboard. As you have an older softmod it might be in C:\ or E:\. The easiest way is to find the config file for your dash (if your dash is Evox the it's evox.ini), make a small edit to the Menu, then reboot - when you find the right one the menu will have changed.
Finally, you copy the xbmc shortcut and config file to your current dashboard location, and give it and its config file the same name as your current dashboard (obviously with different extensions). When you reboot you'll have XBMC as your dash - but if it goes wrong just boot with Frostys / AID and have another go. So long as you don't mess with C:\xboxdash.xbe you'll be fine!!!

Btw., i renamed the default.xbe (which normally would start UnleashX) to default_BACKUP.xbe ...
Well, when i would like to start UnleashX, i have to choose this file (default_BACKUP.xbe) in E:/dash.
That's way too complicated
Is there any way i can start UnleashX as an app from inside the programs-menu of XBMC?
Please, could you explain how to do that?
