If you looking for some tips on how to dual boot your computer with Windows 7 and Ubuntu this might help you out.
The fist thing i did was reboot my computer, After that i i pressed “Ctrl I” to get in to the raid menu. Then i started to set up the raid and i did 2 hard drives for Windows and another 2 for Ubuntu. The raid is set up so one of the hard drives just are a mirror of the other one. so if it should crash you have everything saved on the mirrored one. When the raid was done i started to install my Windows 7 from the disk then i choose to put it on the volume 0 raid witch is the first one of the raids we did. Then you just install windows as usual. I prefer the windows professional but that’s just me you can take whatever. When its done you restart your computer. Then you changing the boot order to Cd or USB depending on how you have your Ubuntu media installation. Then you choose the other hard drives that you made an rain on. After that you install it as usually just make sure it is on the right hard drive. When you done that then you should reboot your computer to see if it works. If it works then you can go in to the bios and change the hard drives order so you can choose if you wan’t Windows 7 or Ubuntu to start up first.
