Boot the system using a live CD, such as the SL live CD, a Knoppix CD. Or in our case I would PXE boot the system in a RAMDISK mode (ie. root filesystem is a RAMDISK). Then: e2label /dev/hda1 to check that hda1 has been labelled properly as '/' Then e2label /dev/hda1 / That might not cure the problem - you might have to mount /dev/hda1 /mnt/hda1 chroot /mnt/hda1 grub-install ie. re-install grub if you think it has not installed properly. From your error message, I suspect grub is OK and that the filesystem is not labelled properly as '/' An alternative way is to use the command line propmpt in Grub and give different options to the kernel, root= <my root partition > -- John Hearns Senior HPC Engineer Streamline Computing, The Innovation Centre, Warwick Technology Park, Gallows Hill, Warwick CV34 6UW Office: 01926 623130 Mobile: 07841 231235
