Well i had three Os on my laptop i.e windows XP, Sun Solaris 9 and redhat linux 8. I needed to install sun java dektop system which is basically SUSE linux as far as i know. I had some free space in logical partition in windows XP. I deleted that and installed JDS on that location and then booted with linux 8 cd and edited grub.conf to include the title and parttion for JDS and installed grub again as SUSE deleted that. Now when i boot i have the four OS listed in grub loader and all three boot fine except JDS and says
"error no.13 : invalid or not executable format"
Donna kow how to proceede from here
