http://ubuntuforums.org – I have a software raid 0 setup with dual booting Windows 7 and Ubuntu 12.04. The GRUB bootloader that is already on the hard drive seems to work fine. However, since the latest package update for grub, it refuses to install the new version to the hard disk. grub-install throws the following error: /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/<raid name>_RAID0p9. Check your device.map. Auto-detection of a filesystem of /dev/mapper/<raid name>_RAID0p9 failed. Try with --recheck. If the problem persists please report this together with the output of &qu (Hardware)
