Hi folks. i have a pc running windows 2000 professional which now fails to boot and is asking for the service pack 4 disc so that it can do a repair. i dont have the service pack 4 disk. i have downloaded the sp4 from microsoft page, but this is a self extracting installation file as opposed to the sp4 disc which holds multiple folders the various .inf files that i require for the repair. Question 1. can i just run the sp4 exe file if i can get the machine into dos mode, or do i need windows 2000 to be running before the sp4 can be deployed ? Question 2. does anyone know where i can get a .iso file of this disc which i could then burn onto a disc ? Any other ideas would be welcome. Thanks to all in advance.
