That machine's standard software complement appears to include an OEM (Original Equipment Manufacturor) version of Roxio's
Record Now (formerly Sonic RecordNow). OEM versions of software included with a PC purchase frequently are somewhat limited in capability, but any OEM burning app should provide a casual user plenty of usability, and RecordNow is an able, reliable, simple-to-use app, IMO. Look in your Program File for something in part named or resembling "RecordNow" - its possible also it was not installed at shipping but is on a disc which came with your machine - but seems to me most likely it oughtta be already factory installed. Anyhow, once you get to where you can open the app, consult its "Help" file for detailed instructions. The support page section of the vendor's website (linked earlier) also offers a FAQ, some tutorials, and a discussion board.
