My Laptop Toshiba Satellite A40 failed to load Windows XP Proffesional Service pack 2. It has a password and when I tried to boot from a CD/ROM the password prevents it. When you power it, windows loads and hangs and keeps restarting even in safe mode or normally. How do I boot from a CD ROM or flash disk because I suspect windows is corrupted ? How can I remove or bypass the password so that I can boot from a CD ROM or flash disk? I have the recovery CD but because of the password I failed to carry the recovery process.
When you boot up to the log in screen type in administrator as user to log in if you cant log in during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS using the arrow keys scroll down to set user password or supervisor password you can change or remove your password from there The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

note after you have loaded the operating system you should go back and change the first boot device to failsafe or optimised defaults
after windows has loaded
your computer will automatically restart it might restart 2 times one to finish the installation
the next will be because the operating system is loaded and will boot from your cd
if your installation disk is only a service pack 1 or 2 you might need to create an xp sp3 disk

if you have a copy of windows service pack there is a program that allows you add service pack 3 to it so you have a copy of xp sp3
