[visitnag]

Hi,

I have first installed windows7 ultimate and later UBUNTU 12.10. Later I have upgraded my win-7 with windows 8 pro.
Now my problem is I am unable to access UBUNTU as my boot loader is missing. Kindly help me to recover the boot loader.

Help is appreciated.

Thank you in adavance

a- boot with an Ubuntu live CD, option 'Try Ubuntu'
b- Open a terminal then do
sudo mount /dev/sdaX /mnt
(replace X with the number of the partition where Ubuntu is installed, also assuming your hard drive is SDA)
sudo grub-install --root-directory=/mnt/ /dev/sda
c- reboot, you should have Ubuntu by now
sudo update-grub
reboot , you should see options to boot Ubuntu & Windows

Help me please...... or Do I have to reinstall UBUNTU?

May be u remember that at the time of Ubuntu installation how many ext partitions you have created.

Just mount each /dev/sdaX one by oneby creating few temporary folders, try to read the content of these folder you get know know on which partions you installed /root, /home, swap etc.

X - represent partion number.;)

Is there any particular reason why you do not want to use Ubuntu only?
