So I did like evry time, insert disk, restarted pc and then "press any key to boot from cd" like many times before.
But this time I got weird error saying a5tt816d.sys is missing cant continue setup press any key to restart.
So I thought its maybe something wrong with cd, havent used it for like 2-3 months.
I downloaded Windows xp sp3 burned it and tryed again, and again same error
Any ideas what causing this?
