Hi,

Can someone help with this booting issue?

My PC has 2 hard drives, one IDE and one Sata, with several disk partitions on the Sata drive and with both Windows XP and CentOS residing on the same larger Sata drive. It could dual boot into either CentOS or Windows XP until recently.

I recently installed a newer version of CentOS over the same old Linux partition. When booting up there is now a "grub>" prompt and nothing happens after this.

I typed boot and got:

Error 8: Kernel most be loaded before booting.

I boot into the Rescue mode using CD 1 of CentOS. Here is the output of fdisk -l, /boot/grub/device.map, /boot/grub/grub.conf, df -h. What changes are needed so that grub will display a boot menu instead of the grub prompt and will boot properly? Thank you.

fdisk -l
