If you boot rescue disk, but don't try to mount the system, can you run fsck on the linux partitions? Is that error from step 4 from grub, or after the kernel starts booting? If the latter, and your root filesystem is a Logical Volume, you might replace the 'root=/dev/hda4' with 'root=/dev/VolGroup00/LogVol00' or whatever the device name is for your configuration. Is there any reason you're not using RAID-1? Keeps your backup in sync automatically in real time, and works with LVM... I've never heard of Acronis, so I can't speak to it's abilities, but I'm typically suspicious of windows-based software when dealing with linux partitions. HTH, Matt
