Thanks for any help including info on how to go back to grub legacy if necessary. Did you generate the config with grub2-mkconfig -o /boot/grub/grub.cfg after that? Attach grub.cfg here and your /boot directory listing. Also the boot messages. If you want to get GRUB 0.97 back, it should be simple: 1. Boot into systemrescuecd 2. Chroot into you Gentoo (see the handbook) 3. emerge -C grub 4. emerge grub:0 5. Run grub-install
[gentoo-user] grub2 upgrade not working
Hello, I have been searching the web for help on this but no luck. I have just upgraded from grub legacy to grub2. Followed the gentoo docs and grub2 will not boot. It hangs in the beginning with the messages: Loading Linux 3.10.17-gentoo ... Loading initial ramdisk ... Here is the section I try to run on my grub.conf root (hd0,0) kernel /boot/vmlinuz root=/dev/sda3 dolvm initrd /boot/initramfs-genkernel-x86_64-3.10.17-gentoo I used genkernel to create the initramfs using the options: --lvm --disklabel --firmware --no-ramdisk-modules. The system booted using the old grub legacy. I would be also interested in information on how to completely wipe out grub2 from my system and go back to grub legacy. Thank you for your help. -- Valmor

This file is formed automatically by grub2- mkconfig command, you have to edit the parameters in /etc/default/grub.
