Forgot Admin password? Performing Recovery Console in an easy way

While performing the Recovery of Windows OS, it asks for the administrator password.
If u dont know/forgot it, then u can follow the below steps to escape from it.

First boot in to the windows, as mentioned in the post http://sureshmuchenthula.blogspot.in/2012/04/to-boot-into-windows-after-removing.html

Then, Start > Run > type "regedit"
Now, navigate to the below section.

HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > Setup > RecoveryConsole

Here, change the value of DWORD to 1. Then restart the windows and perform the Repair option. When it asks for the administrator password, just press "Enter". 

That's it.

To boot into windows, after removing the linux from a dual boot system, without a windows CD

But, if windows cd is not available currently for you, then u can follow the following procedure, to temporarily login into windows. This has to be done every time, if you don’t restore the mbr.

Steps:

1. grub> rootnoverity (hd0,0)
2. grub> makeactive
3. grub> chainloader +1
4. grub> boot

Now, you will be logged into the windows OS.
Note that, this works temporarily. This has to be done every time you start the system, until the mbr is restored with the Recovery Console.
