Did you install windows after Ubuntu? If it is the case then you will need to recover the Grub. Get Ubuntu Live cd, boot from it and then on the terminal use:

sudo grub-install /dev/sdX

Where X is the name of your drive, probably sda.

hi


i have given the command

>sudo grub-install /dev/sda1

output comes out
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub(is /dev mounted ? )
no path or device is specified

Where did you give the command? And you should not install in a partition. Rather install it in MBR of your HDD.

sudo grub-install /dev/sda.

See the difference. Its sda NOT sda1.

hi


by using
>sudo grub-install /dev/sda i am getting the same error .

Where are you giving this command? How do you do that? Can you give more information? And are you able to boot Ubuntu or are you using Live CD?

hi

i am not able to boot ubuntu because i have installed window . now i am using ubuntu live cd . and i am getting this errors

pls help

Ok. Can you see the HDD from the Live CD? What does sudo fdisk -l give?
