Sorry for replying to my own but I had a tinker with the grub.conf from FC2 (hdb). It used to be... #boot=/dev/hda default=0 timeout=10 splashimage=(hd1,0)/grub/splash.xpm.gz title Fedora Core (2.6.5-1.358) root (hd1,0) kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/1 rhgb quiet initrd /initrd-2.6.5-1.358.img title FC1 rootnoverify (hd0,0) chainloader +1 Then I added between the two titles... title Fedora Core 1 (2.4.22-1.2188.nptl) root (hd0,0) kernel /vmlinuz-2.4.22-1.2188.nptl ro root=LABEL=/ rhgb quiet initrd /initrd-2.4.22-1.2188.nptl.img And that lets me boot into FC1 on hda now :) But I just wondered if I'd got the kernel line right, for 'Fedora Core 1', should I have copied the LABEL exactly including the "1" ? After booting back into FC1 on hda I checked the grub.conf and the line was ... kernel /vmlinuz-2.4.22-1.2188.nptl ro root=LABEL=/ hdc=ide-scsi rhgb Should I add in "hdc=ide-scsi" to the grub.conf I'm now using from hdb? I presume that's the CDROM? -- Dave
