I installed SP4 for Windows 2000 on my home computer and it won't boot up!
I searched the internet (better late then never :-( ) to find that many users have faced similar problems. I found various solutions including bad sectors on hard-disk, ESCD problems, card problems, USB problems. But to my bad luck nothing worked for me. Even tried renaming the mup.sys file which was the last one to get loaded. But no luck.
Today I want to try the setup/recovery CD and see how it goes.
I will always hate Windows and its service packs.
