Looking at some GRUB entries for Fedora Core 4 and Red Hat 9.0 Linux, on different PCs around here, they seem to use the same syntax (see some examples below). What worked for one ought to work for the other in a similar fashion. title Fedora Core (2.6.14-1.1637_FC4) root (hd0,0) kernel /vmlinuz-2.6.14-1.1637_FC4 ro root=/dev/hda7 acpi=force initrd /initrd-2.6.14-1.1637_FC4.img title Fedora Core 4 (2.6.11-1.1369_FC4) root (hd0,0) kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/1 initrd /initrd-2.6.11-1.1369_FC4.img title Red Hat 9.0 Linux (2.4.20-31.9) root (hd1,0) kernel /vmlinuz-2.4.20-31.9 ro root=/dev/hdb7 hdc=ide-scsi initrd /initrd-2.4.20-31.9.img > How can I boot into FC4? See the other message about using a GRUB boot disk. But you've not made things exactly clear about what you're trying. There's a plethora of ways you could manage this: You always want to boot from a floppy? You just need to do that to fix things up? Would you want to set up a bootloader on the hard disk? Would you want to do that to use the XP bootloader or GRUB? -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
