The plot thickens ..... # grub-install --recheck /dev/sdc3 Could not find device for /boot: Not found or not a block device I unplugged all but the root drive and it boots perfectly. Progressively replugging all the drives seems to have random results. There is one IDE drive and three SATA, one of which is the rood drive and another one is in a caddy. I have had as many as two of the four extra drives running but can't get them all to go at once. I'm beginning to think it's a BIOS/motherboard problem. I've just rebooted again with only the boot drive plugged in. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
