hello,
i have intel pentium dual core T4300 2.10ghz processor in dell inspiron laptop. i had windows vista home basic by default and then i got ubuntu 9.04 installed on it from one of my friend. i was using ubuntu mostly (and upgraded it to ubuntu 9.10)as i never liked vista. so i installed windows 7 over windows vista. now vista is gone and windows 7 is working. but i no more see the boot options and cant access ubuntu at all. the boot options (F12) does not show linux partition at all. however the linux partition is seen in device manager. but its only seen.
how do i retrieve my old boot options including linux os? which asks me which os to boot from.

please help me asap. i am in genuine urgency.
thanks and regards,
himanee.

Hi himanee.

You should boot with a live CD. Ubuntu 9.04 or Ubuntu 9.10 will work for this. Then you must chroot to the partition where your Ubuntu is installed. After this, you must use the grub-install command in order to restore your boot manager.
If you need more help with any of this commands, let me know.

Cheers.
