How to Recover lost XP Password in Dual OS System (Windows 7 Home Basic and Windows XP Professional SP3)

Hi Folks,

I have a Sony VAIO laptop. I have two operating systems installed there. One is Windows 7 Home Basic and Another one is Windows XP Professional Service Pack 3.

I lost my windows XP password. Couldn't able to log in to it.

I have googled and asked to press CTRL + ALT + DEL twice to go to administrator mode. But that too fails. It also asks for password. Blank password didn't accept there.

Since I have two operating systems, if I use BOOT CD will it affect another operating system (Windows 7 Home Premium)?

Could you please help me to recover the password or to erase the passwords.


Hi Sabarish Sundaram,
Using a boot CD of Windows XP might cause some issue when the system is in a dual boot state.
