i just got a cpu from a friend and the hard drive lights just stay on red. any ideas

the plug to the motherboard may be placed wrong. check that

did all in right spot they were told from a repair guy(close friend of their familiy) that they need a new mainboard. so they gave it to me and i just put the hard drive in my cpu and it works fine. now is their a way i can use win 98 thats installed on the old hard drive? like at school our cpu start up and right away it will ask u if we want to use win 98 or win 200 thats what i want. any ideas

So 98 is already on that disc, but on a different computer?

I'm sure it will boot up. I've never tried that before.

i took the hard drive from the broken cpu and added it to my cpu as a slave. would i have to have the old hard drive as the master to boot off of it. i got to find a way to be able to select which os i want to use.

You need to edit you boot.ini file for your primary hard drive. What OS do you have on the primary drive?

The simple answer is yes. The C: drive needs to contain the OS. What you can do is make the HD with 98 your master drive, and then do a side by side install of 2000 next to it. 2000 should automatically recognize an OS installed and give you the option to install next to 98. Then when you boot 2000 will bring up a menu right away asking what OS you want to use.

That what your looking for?

yes and thank you but i booted off the old hard drive and win 98 was crupted so i just formated it and ill use it for my digital pics and mp3s. its only a 4 gig but it works

That works too.

yep
