If you look at the output of ls -la /boot there is another folder /boot and within this a symlink /boot (./) By copying the kernel to this folder and modifiying the grub.conf in the associated /grub folder the the new kernel boots. Question is how did I come to have a cascade of boot folders and how do I get things back the way they should be? Don't know how you got there, but to get things back to normal you should remove /boot/boot and make it a symlink to /boot: cd /boot rm -rf boot ln -s . boot I would also revise grub.conf a bit: default 0 timeout 30 root (hd0,0) splashimage=/grub/splash.xpm.gz title=Gentoo 2.6.22-r2 kernel /kernel-2.6.22-r2 root=/dev/sda3 video=vesafb:mtrr,ywrap,[EMAIL PROTECTED] - On one line, of course title=Gentoo 2.6.24-r8 kernel /kernel-2.6.24-r8 root=/dev/sda3 video=vesafb:mtrr,ywrap,[EMAIL PROTECTED] Optionally, you could also reinstall grub to your MBR, by running grub (or was it grub-shell?) and issue the following commands: root (hd0,0) setup (hd0) HTH...

Yes grub is install properly and yes the boot partition was mounted when I copied the new kernel across and changed the grub.conf. What's really confusing me is there's no syntax error in the grub.conf that I can see, and the first kernel on the list boots fine. Anyone got any cluse as to why grub can't see the second kernel?

Re: [gentoo-user] grub boot problem
one question: why don't you use 'make install' and have a 'vmlinuz' and 'vmlinuz.old' entry in menu.lst/grub.conf? that solves/prevents lots of errors. -- gentoo-user@lists.gentoo.org mailing list

Matt Ok, I figured out the problem, but no why it's happened. If you look at the output of ls -la /boot there is another folder /boot and within this a symlink /boot (./) By copying the kernel to this folder and modifiying the grub.conf in the associated /grub folder the the new kernel boots. Question is how did I come to have a cascade of boot folders and how do I get things back the way they should be? Matt -- %%% Dr. Matthew R.
