I have my original set of 2, 150GB drives set in RAID 0 with mutiple OS's on it. 2-XP's, 1-Vista and 1-Win7. I disconnected this RAID set and installed a new SSD and installed Win 7 on that. When I installed everything together and boot, it goes into the boot screen giving me the option of the different OS's I've installed ACCEPT the new SSD. The only way I can boot to it is to go into the BIOS and change the RAID option to AHCI and re-boot which then boots directly into the new SSD with no choice of the other OS's to use.

Is there anyway of booting to the screen to show the different OS choices including the new SSD Win7? In other words, it would let me be able to pick from the 2 Win 7's with out having to change the boot sequense? Or does it have to do with one Win 7 being on a RAID set and the new one is not?
