What is make/model of the computer and have you created the system recovery media set yet which most off the shelf computers come with? If you havent created this yet you should get like two 8GB Flash Drives ready or ability to burn about 4 DVD-R's with the recovery media. In your system usually under the manufacturer name in Program Files etc such as Toshiba, Dell, eMachine, HP, etc you should find a tools, utilities, or other option to create the system restore or recovery media. Some systems its a 1 time shot where you can only create the set 1 time and then your in trouble if you created it but lost the media that was created. Some warn you not to make extras of them but they allow you to do so such as my Toshiba Netbook that I lost 1 of 2 USB sticks with the recovery media, it allowed me to create a new set and just warned me that your only suppose to do this once even though it was my 2nd time running that media creation utility and the media worked to perform the 160GB 5400RPM HDD to 120GB SSD upgrade.
