I have a MSI GT780DXR that currently is booting windows 7. I've been trying to dual boot windows 7 and ubuntu for some time now.

Here's specs that I think would make a difference

• Windows 7
• 500GB*2 RAID 0 hard drives. (Hardware RAID I'm not sure if it's a dedicated RAID card though) 7200RPM
• Nvidia GT570M

Background: I tried to install 12.04 (64 bit) a few times but the Desktop live cd and pendrive boots with a black screen. I've tried wubi but it boots to a black screen as well. I then tried the alternative 12.04 (64 bit) and went through the installation all the way til partitioning. I let Ubuntu notice the raid setup and I setup my swap, /, and home drives, I used my free space to create the three partitions. I tried to resize the windows drive and it told me I couldn't and to be happy with my current setup. When I finally got past I got an error on installing GRUB 2 and decided to skip it and continued on to finish installation. When I tried to boot up I got an invalid partition table error. Windows recovery disc, and a GPARTED live cd couldn't find any hard drives. I ended up following advice and typed this into the recovery command prompt.

• bootrec /fixmbr
• bootrec /fixboot
• bootrec /rebuildBcd

It worked and here I am now. The question is, how would I be able to dual boot windows 7 and Ubuntu 12.04 with this information? Thanks,
