I first installed windows 7 in a partition. Then installed ubuntu in another partition. But i am not able to choose between those 2. It is directly going into windows 7. Please
You need Ubuntu 10.10 livecd for repairing grub boot loader . Here assuming the Ubuntu partition is sda7. Boot up ubuntu from the livecd,open terminal and run:
and see what is your linux partition and note it I assume it sda7 here.
