The Error 16 is from grub: "Inconsistent filesystem structure". I assumed grub was complaining about the initrd image, but not sure of this now. I should be able to do an fsck on the Linux partitions from the Linux rescue CD. I can see all my directories and files when mounted in rescue mode. I did try "root=/dev/VolGroup00/LogVol00", and "root=/LABEL=/", in place of "root=/dev/hda4" on the "kernel" line, but got the same result. Acronis works almost like dd, and can do a verbatim copy of a disk. I looked into everything else, before I went with this. regards, John --- Matthew Gillen wrote: > John Koshi wrote: > > Hi, > > > > I have a problem with the grub bootloader, as follows.
