This would be normal as your use start up file is prob invalid with UAE, especially if you have Cybergraphics or you use special 040 library ot if you had 060, The best way would be to hold right and left mouse button down while booting and select boot without startup sequence and say ok to all exeptions you should bet to the grey screen and type loadwb. You should eventualy get to Workbench.
Of course this is if I remember correctly.
