Grub error 15
After hitting return in the grub prompt you get something similar to this one?
Code: Booting 'gentoo Linux'

root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel (hd0,0)/boot/kernel-2.4.20 root=/dev/hda3 vga=792

Error 15: File not found
Press any key to continue... info grub wrote: 15 : File not found
This error is returned if the specified file name cannot be found, but everything else (like the disk/partition info) is OK.
If it's the kernel that it's missing (bzImage, kernel...):make sure that the file it is referring to exists on your boot partition.

To find out what the exact name of your kernel is, first boot from the live-cd or into your existing linux installation. Then mount /boot if you've got a seperate partition, or mount / if you don't. Then do the following: Code: cd /boot
ls This will list all the kernels that you've got on your boot partition.

If your kernel is missing make sure that you compiled a kernel either with genkernel or make menuconfig Code: cd /usr/src/linux/
make menuconfig and you copied it to your boot partition. Code: cp /usr/src/linux/arch/[your architecture, e.g. i386]/boot/bzImage /boot/

However if this error is caused while trying to install grub. And is similar to this one: Code: grub> root (hd0,0)
Filesystem type is xfs, partition type 0x83

grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... no

Error 15: File not found First of all make sure that you changed root(hd0,0) and setup (hd0) according to your systems specifications.

It may also be possible that grub uses other numbers for your drives than your kernel. So although it may be hda it could be that it is not hd0. However usually this is not the case.

Or else give this line a try provided by dirtboy Code: grub-install /dev/bootdevice

If all else fails make sure that your partition is not somehow corrupt. Be sure that you are able to great symbolic links.
