I recently bought an Asus sabertooth 990fx mobo and amd bullozer 8150 processor. With 2x2 ocz SSD's and 1x2 HDD's striping and two sata optical drives I have used all the internal sata connectors. I have one e-sata 2 TB external disk for back-up.
As an IDE port is missing and the external disk is quite slow it is obvious I want to use the fake raid disks for installing the o.s.'s. On my previous mobo (msi 790fx-gd70) it has never been a problem to install grub2 on the raid arrays, but with the present configuration it is impossible to install grub2 be it ubuntu, fedora or kororaa. I will confine myself to ubuntu 12.04/12.10 d.b. x64.
The 12.04 live usb (made with unetbootin) does not install at all (internal errors) The alternate cd gets jammed on grub2 installation just like the live usb of 12.10 d.b.. When I enter the bootloader location during installation f.i. : /dev/mapper/pdc_bagbffcdig and it reaches the stage of creating the bootloader it says: can't install in /dev/sda. This is understandable because I don't have sda (the external disk is named sdg). If I then re-enter the fake raid disk it keeps saying fatal error and lets my choose between quitting and installing without bootloader. Manual installation of grub2 using the live usb is no success either.
I have not found a manual yet focussed on installing grub2 on striping arrays.
Has anybody got an idea how to solve this problem?
