I've never had this problem before with my A1200s, its always been easy, but I've fitted a new HD to my toy A600... and I can see the drive, partition it, format the partitions, make one of them bootable and copy files to it, but when I try to boot the machine....nothing!
I can use FFS with KS 2 can't I?
I'm probably being really stupid, but I'd rather someone enlighten me so I can have a 'doh!' moment, rather than carry on tearing my hair out...
Thanks
