I have 2 80 Gb HDD's with a RAID 0 motherboard configuration (Intel Z77, fakeRAID) with a 100 Gb partition running Windows 7 and a 60 Gb partition where I would like to install Ubuntu 12.10. However, even though the installer seems to correctly detect the RAID 0 array, GRUB2 is not installed and the computer boots into Windows normally. The same thing does not happen when installing Fedora 17. The installer (Anaconda) also detects the disk array, but GRUB2 installation is successful. What exactly are the differences between Ubiquity and Anaconda? And is there a way to correctly install GRUB2 in a fakeRAID system, since there are no alternative Ubuntu CDs?

I've found an effective way to do this. As Rich.T wrote, the /boot should be a separate partition at the start of the disk array. However, Ubiquity still won't correctly install the bootloader, so a workaround is to boot with an image of Ubuntu Secure Remix and run the Boot-Repair tool, following each procedure. An alternative way could be to either install the whole OS from the Secure Remix CD or to install Boot-Repair in the normal Ubuntu Live CD, however I have not tested it so I cannot guarantee they would work.



NOTE: It is also required that both Ubuntu CDs boot into non-UEFI mode, otherwise it will not work.
