Hi! I have a strange problem with grub. I had fedora installed on a SATA drive, 7th partition. I started to have problems with the disk so I got a new one. I forgot to buy the SATA cable so, for a few days I replaced the bad disk with the new one, doing a fresh install, this time on the 5th partition. No problems there. Then, when I connected both disks at the same time a strange boot problem appeared. The symptom is that hd0 is sdb and hd1 is sda. This has taken me a while to figure out. I even did a new clean installation with both disks connected. The installation took sda as the new disk and sdb as the old one, as expected, but when I tried to reboot, the word "GRUB" filled the screen and it did not boot. The strange thing is that grub doesn't work the same way when I boot from the CD in rescue mode, than when it boots from the hard drive. I re-installed grub manually and all the commands given to the grub console were accepted fine. The commands I typed were the same I had in the grub.conf file: title Fedora Core (2.6.18-1.2849.fc6) root (hd0,4) kernel /boot/vmlinuz-2.6.18-1.2849.fc6 ro root=/dev/sda5 vga=791 initrd /boot/initrd-2.6.18-1.2849.fc6.img To be able to boot I had to install grub in the sdb disk, and change the "root (hd0,4)" to "root (hd1,4)"!!! Is this a fedora issue or should I sent it to grub developers? what do you think? Thanks for a great linux distribution! Pedro. PS: The BIOS can only specify "Hard Disk" as the boot device. No distinction between first or second disk.
