Hi, I installed the 2.6.10-1-multimedia-k7 kernel via synaptic. and then i gave the update-grub coomand. menu.lst was automatically updated; this is the new entry: title aGNUla/DeMuDi, kernel 2.6.10-1-multimedia-k7 root (hd2,0) kernel /boot/vmlinuz-2.6.10-1-multimedia-k7 root=/dev/hdc1 ro savedefault boot now when i boot, grub launches, i choose 2.6.10-1-multimedia-k7. it starts to load and then i get this error: VFS: cannot open root device 'hdc1" or unknown-block (0-0) Please append a correct "root=" boot option Kernel Panic - not syncing : VFS: Unable to mount root fs on unknown-block(0-0) I can still boot the 2.4.25 kernel and windowsxp. I also did this, on the advice of Free: # dpkg -i kernel-image-2.6.10-1-multimedia-k7 dpkg: error processing kernel-image-2.6.10-1-multimedia-k7 (--install) cannot access archive: No such file or directory error were encountered while processing: kernel-image-2.6.10-1-multimedia-k7 Gustin inquired about initrd.img-2.6.10-1-multimedia. And I found that there in no entry in menu.lst about it nor is there such a file in /boot directory. Any ideas? guerrier
