Previously I have installed Windows XP then Windows 7 in different drives of my computer. Later installed Ubuntu 10.10 inside Windows 7 and upgraded it to 11.04. After that Accidentally I have formatted Windows XP drive from Ubuntu. I installed XP again to the same drive. I tried to repair Windows 7 and it worked fine, but the problem is I can boot only Windows 7. I have used BCDEdit tool to add entry to boot menu. This also worked fine that I am able to boot both Windows 7 & Windows XP.
Now I want to boot Ubuntu 11.04 also using already installed partition. I don't want install it again(as I have to update it to 11.04 again).
I have Windows XP in C drive, Windows 7 in D drive and Ubuntu 11.04 in E drive.
I am able to boot XP & 7, now want to add Ubuntu also, Please help me...
