i need help installing mac os x tiger, disc 2

my macbook successfully installed disc 1 of mac os x tiger, within minutes, however when it asks for me to insert disc 2, and i do so, it almost finishes installing the disc, then an error message pops up, saying "there were errors installing the software, please try installing again" i have repeated this process at least 20 times, and the same thing keeps happening. i can't even use my computer regularly since everytime i open it up this happens! please help!
