One way is to buy the DVD's from amazon.com for about $14.00 for BG2 and the expansion. Try also e-bay (that's where I bought the collectors editions). Definitely worth the time and money for this fabulous classic! It is better than EE, save for the Bag of Holding from the Hexxat quest, but even that item is definitely not needed.
E.g. here:
https://www.amazon.com/s/ref=nb_sb_ss_i_9_8?url=search-alias%3Daps&field-keywords=baldur%27s+gate+2&sprefix=baldur%27s%2Caps%2C232&crid=180377HF3P01F Or search for: baldur's gate 4-in-1 box set
See my walkthroughs which include installation steps and a few basic modding tips (page 4):
