[aneslin85]

guys, in my laptop I used Vista, and I installed Ubuntu with wubi.
and yesterday I did a win7 clean instalation.
so its overwrite my old bootloader / grub

so, how can I get my ubuntu back ? without instaling it again.

If 'sda' is the hard-disk both operating systems are on (verify with 'sudo fdisk -l') you can restore GRUB to the mbr using a live CD terminal:

sudo grub-install /dev/sda

You did a clean install so your Ubuntu wubi install is formatted with the rest of your Vista install. Wubi is a file inside the windows filesystem, when windows 7 formatted Vista's partition wubi went with it!

Ubuntu was installed via wubi, so when the OP did a clean install of windows 7 the Ubuntu wubi install was formatted with the rest of Vista.

As mentioned - if u used wubi - that was installed WITHIN the windows area, it's gone.

post the output of
sudo fdisk -l

Phill.
