I've installed Mythbuntu on my computer but it won't boot anymore, the only thing it does is write:
Grub stage 1.5
Error 15
file not found...
When I load it with a live-cd and search, there is no file /boot/grub/ and when I log into the grub console (sudo grub) and try to fix it :
root (hd0,5)
setup (hd0)
It tells me that the files
/boot/grub/ /grub/
are not found. (Ps: partition 6 is the good one but I've tried them all up and none is working)
