Fail to entering ubuntu 10.04 with raid0?

Hi, guys. If the easybcd can get the ubuntu menu but I fail to enter ubuntu, what's the problem could it be? Or did it cause by easybcd or ubuntu? My pc condition is nvidia raid0 with win7, and a unenterable ubuntu 10.04... I use the beta 97 of easybcd, leading ubuntu with grub2 and ext3 format. When I press enter ubuntu, it just stuck at the ubuntu screen with the dots not moving :wtf:, I wish some could help me :|.
I think the boot configuration which EasyBCD setups for Linux in a dual-boot situation like yours doesn't work with Raid 0. Maybe you can install Ubuntu to a separate non-RAID HDD?
