Well, that's disturbing. I wonder why all those other partitions (after sda2) are so configured. I don't remember the exact error message from cfdisk, but it was something along the lines of the partition not ending on a sector boundary or a cylinder boundary. Nothing about type ID. > (FWIW: A list of partition types I found on the web lists ID 27 > as "'PQservice' -- Acer hidden rescue partition. Must be FAT32. > Press Alt-F10 during boot to start this.

I think the manual is rather confusingly written because it claims that the recovery process will (or can, depending upon which option you choose) destroy all other partitions, but I suspect that it really won't. I bet it leaves /dev/sda1 in tact. Michael _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
