i have something similar happened to me sometime last week when i re-installed windows on my PC. my problem was my old liteon dvd drive (more than 2 years old). so what i did when it reached some reading error during installation is; remove the disc then put in the other one though i knew it's the incorrect disc. this is to re-initialise the drive so it will start the spin-up. when it gave the same error dialog, i inserted the correct disc then it read correctly & continued installing.

it may take a few tries before working.

be patient as the game is worth it. game on!
