Error 15: File Not Found Plz help explain

[Fuzzanator]

I just finished a quad boot and when I try to load Ubuntu I get this message
kernel /boot/vmlinuz-2.6.27-7generic root=UUID=666e7f64-55a0-439d-91e5-dc83309cc326 ro quiet splash

Error 15: File not found.

can someone explain to me what the heck this all means. I am new to the linux world so I really don't have a clue to any details that I have found on the internet

What do you mean by "I just finished a quad boot"?
Usually the error message you posted means that the kernel line is wrong and or the kernel is actually missing. Did you try to compile your own kernel or did you modify GRUB?

Check for grub stage1

When It throws you back to the list of choices,
Press "c" It will bring you to a Grub prompt.

grub>

If you have it separate '/boot'

> find /grub/stage1

If you dont have it separate

> find /boot/grub/stage1

One of these commands will give you output like this

root (hd0,0)

(0,0 Numbers may be different)

Now press Esc.

Back to the selection menu
Select the first boot option & press "e"

Again press "e" on the root option
Change the hd(x,y) to out put you get in those commands

Hit Enter.
Then press "b"

Then make permanent change in /boot/grub/menu.lst

# sudo nano /boot/grub/menu.lst

kernel /boot/vmlinuz-2.6.27-7generic root=UUID=666e7f64-55a0-439d-91e5-dc83309cc326 ro quiet splash

Try replacing UUID with actual root partition of Ubuntu.

kernel /boot/vmlinuz-2.6.27-7generic root=/dev/sdxy ro quiet splash

You can edit kernel Line in GRUB Menu easily. Just highlight Ubuntu title, press e, select kernel line and press e again. Edit line, hit Enter key and press b.
