Hi,earlier i had windows 7 on two partitions and Ubuntu on one.Then I re-installed windows 7 on one partition.Now OS Boot menu is not shown at startup.The new OS starts directly.How can i add entries of old Ubuntu and windows 7?
-Windows 7 OS on a partition
-other Windows 7 OS on another partition
-ubuntu on another partition
Please post screenshot of disk management in Windows 7.
Did you always saw the grub bootmenu on boot or the Windows 7 bootmanager?
Did you reinstall Windows 7 by deleting everything first on that partition (or recreate the partition)?

grub code was in MBR of physical disk. Reinstalling Windows 7 placed a Windows 7 MBR boot code there. So grub code is gone!
ubunut is on 55.74GB partition?

Once inside Windows 7, run EasyBCD. Make sure you're using thelatest and greatestversion!
At this point, go to the "Add Entry," select "Linux," and then select "GRUB2" from the drop-down menu. Give it a descriptive name if you so desire and click the Add Entry button when you're done.
