Found my old Xbox 360 and thought "oh hell yeah, now I can play Halo CE, and not that anniversary crap edition"

Bought new controllers, bought the Xbox Original edition of Halo 1 & 2, tried them out and the Xbox didn't even notice I inserted a disk, bought a replacement disk drive, installed it, and now it only says "Play DVD".....,.,.,..,,,,

When is it OK to surrender to this stupid dream and just buy Halo Anniversary on PC?

Could've spent this money on Halo Infinite, got damnit.....;.,..,,.
