reset root password

I recall that if you boot up to the install cd the root password is not set. From this bootup cd you can reset the installed root password.

Hey Abi0909,

I followed the instructions as mentioned in the link provided by you, I'm still unable to change the password. I did get to the screen where it asks for new UNIX password, however I get an error as below

"authentication token manipulation error
password unchanged"

Can you help me on this....

I also Win 7 OS on my laptop.... if it helps.....

Just use a livecd, login as root and do a quick "passwd" to change the root password since live cd's generally don't come with a root password. If they do they make them fairly obvious like "toor" (root backwards) or something along those lines.

I tried to reset the password from terminal instead of recovery mode as in link provided by Abi & it worked.

Thank you all....
