I've got two HDs in a raid system and Windows 7 installed in a partition. When I try to install Ubuntu in the other partition, the installer says the bootloader can't be installed. I've mounted Windows partition and installed Grub on it, but I'm not able to configure it's menu. When I start the computer, it gets to the standard Grub terminal (doesn't show the options to boot). As I installed Grub in the Windows partition, I have unsuccessfully tried to use C:/boot/grub/menu.lst and C:/boot/grub/grub.conf.
In a few words, I can install both Windows and Ubuntu in the raid system and install grub, but I can't configure grub to boot them (grub menu).
Maybe the answer is here, but I can't figure it out.
Please, help me. I appreciate it.
