    Re: Can't instal bootloader

    You have to decide if you want UEFI or the older BIOS. Many do not understand UEFI and each vendor has done it a bit different even though it is supposed to be a standard.

    When you configure drive I normally suggest both an efi partition which must be first and 200 or 300MB formated FAT32 with boot flag (in gparted), and a bios_grub partition 1MB not formated and with bios_grub flag. Then whatever partitions you want for the system(s) you want to install. You actually do not need both but partitions are small and it gives the options to install either way from a partition stand point.

    In Ubuntu when you boot from UEFI, you should see two different boot options. One is UEFI and should install using UEFI and the efi partition. The other option is the older BIOS/MBR install which will use the bios_grub.

    Ok. So I'm on the last leg of the installation process now. I did what oldfred described, and so I have the following partitions now:

    -----------------

    I told the installer to install the bootloader on the /dev/mapper/sil_biafbiddeice1 partition. Now I got the message saying it is time to reboot. Just crossing my fingers!

    Re: Can't instal bootloader

    Follow up: yet another fail to boot.

    I get no errors during install (did the alternate-iso version this time, due to RAID), but when I reboot my computer says:

    Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key

    I have changed settings in the UEFI/BIOS to pretty much every option avaliable. Every time I get the message above.

    Such a downer. Got this awesome computer, and I can no longer use Ubuntu on it.

    Wow, this isn't that hard guys...

    Almost, just take off the number. Pop in 12.04, do the install as normal, and set the bootloader to install at /dev/mapper/sil_biafbiddeice. That's it.
