Amazing. I tried to install a new FC3 in this "new" computer... and after installing it I got EXACTLY the same error when rebooting.. so I begun to think it maybe cause of the computer :) FYI, the computer is a Compaq EVO D510, wich has a very small format, at expenses of no having neither HD, nor PS/2 ports (only USB) and can not install a second HD. It seems that other ppl had the same troubles I had, see http://www.fedoraforum.org/forum/printthread.php?t=18482 so.. deninitely this computer does something fancy with grub. Solution (just in case someone else will have the same troubles in the future): 1.- Boot "linux rescue" with FC3 disc 1 2.- #chroot /mnt/sysimage 3.- I downoaded lilo from # wget http://dag.wieers.com/packages/lilo/lilo-22.6-1.1.fc3.test.i386.rpm 4.- installed it # rpm -ivh lilo-22.6-1.1.fc3.test.i386.rpm # cp -p /etc/lilo.conf.anaconda /etc/lilo.conf 5.- change linear to lba32 on lilo.conf 6.- #lilo -v -v 7.- Reboot and ready :) Thank you very much all for your help !!! -- This is an email sent via the webforum on http://fcp.homelinux.org http://fcp.homelinux.org/modules/newbb/viewtopic.php?post_id=49686&topic_id=12422&forum=6#forumpost49686
