Thread: Grub sees one OS 12 times!?!?

my laptop dual-boots windows 7 & ubuntu. added logical partition , installed backtrack. i'm triple-booting. grub fine until installed backtrack, grub seems hopelessly confused.

here's output of sudo update-grub ubuntu 11.10 installation:

code:

but in reality i've got installed is:

/dev/sda1 = windows boot
/dev/sda2 = windows7
/dev/sda3 = hidden windows recovery
/dev/sda4 = extended partition
/dev/sda5 = ubuntu 11.10
/dev/sda6 = linux swap
/dev/sda7 = backtrack (which grub reports "ubuntu 10.04")

here's how gparted sees partitions

why grub think there 12 partitions of ubuntu installed? how convince there 1 ubuntu?

with each kernel upgrade new entry added , old 1 remains option in case there wrong old ome
