Q: Bootcamp not working after El Captain Beta installation

Hi,

I had OS X 10.x (possibly Snow Leopard) and Bootcamp (Windows XP). I upgraded OS X to 10.11 El Captain Beta. Unfortunately, I can not use my Windows XP now, it says; 'No bootable device --- insert boot disk press any key' though I start Bootcamp from start up manager. I can see the bootcamp partition and files in mac finder. When I try to select and boot by pressing option key there are only two menu icon 'Mac OS' and 'Recovery 10.11' but no 'bootcamp'. Some information:
