How to log in as root in Guest OS Linux Mint on host Windows Vista using virtual box
 

I am using virtual box with Guest OS Linux Mint on Host OS Windows Vista.
I want to log in as 'root'.
I typed 'su' at the terminal, then it asked for a Password.

Please help me in logging in as root in the system !!!!
I have share some folders on the host with the guest, so please help ASAP.

Thanks..

Linux Mint is based on Ubuntu. Both operating systems do net set a root account. You have to use sudo for administrative tasks.

Here is a more detailed explanation of how 'sudo' works:

Thank you both of you......I have finally entered the root system....!!!!!
BUT.....for sharing a folder on the host system...
I use the code.. "mount -t vboxsf UNIX /home/mint/Animesh"
Here, I get an error...
"mount:unknown file system type 'vboxsf' "

What am I supposed to do now..!!!!!
I am just one step away from my "Share Folder" mission....Please help
