or get second machine and install your OS but you can try another alternative too here.
You can install OS VIRTUALLY. Main advantage of using Virtual os is, you do not have to REBOOT to get into another OS or Spend extra money on Separate hardware just for using other OS occasionally.
VMWARE is leading company for LINUX platform, they have freeware as well as payware applications both for desktop workstation as well as enterprise server market. Here in part-1 I am going to focus only on one application called VMplayer.
VMplayer is application which will let you RUN already configured Virtual Machines(VM). You can even visit http://www.vmware.com/appliances/directory/ and browse through all the Virtual Machines available to download and run, almost all of them are free to get (registration required) and can be run easily with VMplayer.
Some of the VMs I found are as follows:-
----------------------------------------------------------
* SugarCRM :- CRM web-app for linux ( 115MB)
* BackTrack Security :- BackTrack v2.0- Penetration Testing Platform
* Centos5 :- Centos5 Minimum VM
* Microsoft Windows Server 2003 R2 Enterprise Edition Virtual Appliance :- Ready to start Win2k3 server Virtual Machine (1.5GB)
* Microsoft Exchange Server 2007 Virtual Appliance :- Ready to go Win2k7 Exchange server Virtual Machine ( 1.4GB ).
----------------------------------------------------------
You can go to my previous post on getting current VMplayer running on fedora because it does not run out of box.
In my video, I have used Fedora Core 4 vm (old) to test and show VMPlayer DEMO.
