i hv dual boot of windowes 7 but want to remove one of them without using any booting device cd/dvd . :s. Suggest any reliable software
I assume when you say you have dual boot Windows 7, you have two separate instance of Windows 7 running on your machine. And during start up it prompts you to select one installation.
As I am not aware of the exact software/hardware or configuration details of you machine, what I am putting below are generic steps for this problem. So I would suggest you do take backup of your data before proceeding further.
Here are the steps you can follow to get rid of extra installation.
1) Log-in to the Windows 7 instance you want to keep running.
2) Once in go to Start orb, All Programs, Accessories, and right click Command Prompt and select Run as administrator.
3) In command prompt type "bcdedit", this will display the current entries in your BCD store.
4) Note down the identifier for the entry you want to remove.
5) Now on command prompt type "bcdedit /delete <installation identifier you want to remove> /f /cleanup. This will remove the extra option of Windows 7 installation during machine startup.
6) After this you can delete the Windows folder of the installation you just removed from hard disk and use the remaining Windows 7 installation without any problem.
