I tried that, Lilo runs ok, but I still get the kernel panic due to the line in lilo.conf 'root=/dev/sda8'. That suggests that it doesn't like the FS on /dev/sda8 , ie ReiserFS, which must be due to something in the Ubuntu set-up, as the Gentoo stanzas have 'root=/dev/sda3, which is also ReiserFS.

I don't know what you mean by chainload Ubuntu's GRUB; I don't remember your specific choice during the Ubuntu install, only Shall I overwrite the MBR ? , to which I answer No ! . I don't want to learn how to use Grub for this simple test project: Lilo is quite adequate for my normal needs. PS.

Re: [gentoo-user] anyone using Lilo to dual-boot ? -- discovery
Further ideas : I tried booting a Gentoo kernel with the Ubuntu / avoided the kernel panic, but ran into an Ubuntu init error, so there's nothing inherently wrong with /dev/sda8 . Also, I checked the Ubuntu kernel config file, conveniently in /boot , which has ReiserFS configured as a module, whereas Ext2 Ext3 are 'y'. That suggests that it's running into a road-block: it needs to use ReiserFS to start 'init', but can't load modules till it has already started 'init'. In that case, I need to re-install Ubuntu using Ext2 or Ext3 . In fact, it wb as a bug in Ubuntu's advanced install.

No, I must have installed at least 3 Ubuntus in the last 6 months, all of them on reiserfs. No problem booting them. Unless you have stored a kernel image in a partition (e.g. /boot) that your lilo can read I don't think you'll be able to boot Ubuntu: image=/boot/your_Ubuntu_image label=Ubuntu append=ramdisk_size=290 vga=normal initrd=/boot/your_ubuntu_initrd.gz read-only root=/dev/sda8 I don't use LILO so check the above to make sure there are no errors, and adjust it to your circumstances. Finally, to check that your Ubuntu installation is correct you may be able to boot it using the Ubuntu LiveCD (I recall it offers the option to boot a partition on the hard drive, but I'm not 100% sure). -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Thanks, that solved the problem, given that I had identified it as arising from Ubuntu not recognising ReiserFS. I added the 'initrd=...' line booted into Ubuntu successfully; Gentoo doesn't require that line, perhaps because I use no kernel modules. BTW the Ubuntu ramdisk needs 7,9 MB Lilo issues a warning (I didn't use your 'append/vga' lines).
