 Debian installed from Redhat cannot boot Hi, I installed debian by the official manual http://www.debian.org/releases/stabl...paring.en.html under redhat. I am using redhat grub to boot debian. Below is my grub.conf: default=0 timeout=10 splashimage=(hd0,7)/boot/grub/splash.xpm.gz title Red Hat Linux (2.4.20-8) root (hd0,7) kernel /boot/vmlinuz-2.4.20-8 ro root=/dev/hda8 initrd /boot/initrd-2.4.20-8.img title Debian root (hd0,4) kernel /boot/vmlinuz-2.6.3-1-k7 ro root=/dev/hda5 title DOS rootnoverify (hd0,0) chainloader +1 My debian is at /dev/hda5 and i am sure. But when i reboot, select Debian and see: VFS: Cannot open root device "hda5" or unknow-block(0,0) Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on unknow-block(0,0) Can you give me some advice where the problem may be? Thanks very much. Peter Pan      |

Thanks very much. IIRC Debian kernels use initrd (I build my own these days and haven't used a stock Debian kernel in ages). Add "initrd /boot/initrd.img-2.6.3-1-k7" to the Debian section. Check in /boot for the correct file. -- Andy. |
