stevie_velvet: Regarding your “Solution 2g”, using Grub commands, what was returned when you requested:
find /boot/grub/stage1
Also, one thing I have learned about grub-installed run from FC Rescue is that it can really mess things up, even if grub.conf was already configured correctly.
Do you have two partitions with the same name/label? I have done that by accident using PartitionMagic and it really does a number on the boot. When in doubt, use the /dev/... definitions in grub.conf and fstab, instead of the LABEL= format. It is the first thing that I modify when setting up a fresh installation.
Unless you have already done this, make a grub boot floppy or CD (or USB flash drive) (
http://www.gnu.org/software/grub/manual/grub.html) and go through the “find...”, “root...”, “setup ...” commands one time. Running them from FC Rescue will not necessarily give you the same results. The boot floppy looks at the hardware exactly the same way as the MBR Grub Stage1 call, whereas FC Rescue may be loading some drivers to see some of the drives.
