Those with (configuration) GRUB-problems may want to look at:http://www.troubleshooters.com/linux/index.htm
and especially at:http://www.troubleshooters.com/linux/grub/index.htm
Sometimes a better understanding and handhelding by an expert helps. I know it did for me <g>.
Please listen to the usual warnings though. Do not fool around with MBR and booting / partitioning setup without a good tool and a backup copy (on a seperate media or PC !!) of the MBR and the drive(s) partitioning data / partition tables. I use DFSee (http://www.DFSee
,com ) for that but there are others too.
If you value your data and/or existings installations perhaps it is a good idea to backup those beforehand also!
