Taking our the CMOS battery on the motherboard did the trick for me. It erased the password and I was able to load up the OS.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don’t have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

I tried removing the battery for 30 minutes, and reinstalled. Still asking for password before booting. Tried to access by using known manufactory back-door passwords. Didn’t work. It keeps telling me too many unsucessful attempts, must shut down. Cannot enter “setup” or “Boot menu” Tried removing battery for one and a half hours. Same results. It starts to boot, then immediately ask for password. Tried to use Operating system CD, won’t access CD. Any Ideas on how to fix this problem.

How to remove CMOS battery?
I used screwdriver but somehow I ripped off battery support with battery inside it.
