I do agree with Deop, Ubuntu will work absolutely fine.

Bit still if you willing to reset your existing OS root password then please do follow below.

during the booting time by pressing any key on keyboard you will get an option to enter into grub menu and from their you can edit kernal version and reset password by passwd command it will help you to reset password for root which is super user.

It might be an typo

All logs kept under /var/log directory if you using solaris their is slight diff in the location /var/adm

I suggest to use
Ubuntu: http://www.ubuntu.com/

I do agree with Nixsavy & Roobal..

Virtual box is an very good option for you. Even you made any mistake you can roll back to previous step and it's easy to handle/Understand.

Their would be no harm to your Windows 7.

Virtual Box or VMware will work smoothly. But i suggest to use Virtual box easy to understand.

Use of swap is well known to me, Only concern with weather we can install os without it or not ?

Hi Friends,

Do we install redhat or any other Os without an swap partition ?

If Yes, What is the role of swap during the installation or why it's so needed that its an mandatory during the installation?

If No, Explain an installation process ?
