I had installed windows 7 recently and thereby lost my grub. but my Linux partition is still there... I had Ubuntu 14.04 installed previously. I want to reinstall the grub from a live CD.But I don't have the live CD of ubuntu 14.04, I only have the live CD of ubuntu 13.10... is it okay to install grub from it?

Yes, it is perfectly fine to install the GRUB from 13.10 for 14.04. In fact, any distro which is using GRUB2 should be fine for use. However, as long as the Ubuntu installtion is present, you can use the grub
utilities from it to install GRUB. From a live CD/USB, do:
sudo mount /dev/sda1 /mnt
sudo mount /dev/ /mnt/dev -o bind
for i in /dev /dev/pts /proc /sys; do
sudo mount -B $i /mnt/$i;
done
sudo chroot /mnt /bin/bash -l
# From here on you're in the Ubuntu chroot, logged in as root.
grub-install /dev/sda
update-grub
exit # exit the chroot
Of course, use the correct the partitions/disks in place of /dev/sda
and /dev/sda1
. Use the lsblk
command or the GParted application to find out, if you're not sure.
