Ok so I’m trying to install suse 11.0 on my “fake” raid. I have 2 hard drives bios striped raid 0 with Windows XP already installed. When trying to install suse everything goes fine untill it ties to setup Grub. When trying to setup grub I get and Error 21. Partition cannot be found. Any one get dual boot working on a sata “fake” raid?
