Installed new HD, OS's go poof

[psionicinversion]

basically i installed windows 8 yesterday on a unused partition on a hard drive that was currently in there and everything was fine could go into windows 8 and could go into windows 7. Now then i installed a seagate 3TB HD and it came up as is it couldnt read my disk drives to be able to boot from. I reinstalled windows 8 and from the boot options the windows 7 install on my SSD doesnt work. it says it cant access the disk but i can copy stuff from and to it through windows 8. Before at the boot menu it said windows 7 Volume 5. the volume 5 is gone next to it now so anyone got any ideas as to why its stopped working/unrecognizable and the recovery options dont seem to work.

asus sabertooth x58 motherboard

seagate barracuda 3TB (new one i installed)

ocz vertex 2 120GB SSD (windows 7)

Hitachi 3TB HD (storage and program partition)

think its a maxtor (windows 8 partiton and storage partition)

Just so I am aware, IF you disconnect the 3TB drive - does the machine return back to normal?

Sounds like it is trying to boot off it. Go into BIOS and check the disk priority section.
