Every laptop has its own key button in order to access the Bios setup, In Bios setup you can configure your laptop to boot in Cd
Some laptops using the F2, F11, Esc buttons. After the power on press
the button right away when you see it flashing in the screen
Inside the Bios setup, go to the Boot order menu, there a selection that will let you choose the Cd to boot first after selection save the setting, in the bottom of your screen you'll find the menu on how to save the settings you made, sometimes F10 button use to save the settings.
After the Save menu it will automatically restart your computer. Right away insert your bootable Cd in restart mode.
Take a can of air and blow some air onto the laser gently to make sure no dust or dirt is affecting it.
Then go into the BIOS and make sure the cd-rom is the first boot device. Then put your operating system cd into the drive and "press any key" when that message comes up so the system can boot up off of the cd.
If after setting the cd-rom as the 1st boot device you can't get the laptop to boot up off of the OS cd then that means the cd-rom is bad and would need to be replaced. When you boot up off of the cd-rom your in DOS and any viruses or worms wouldn't affect it.
Suggest getting Advanced System Care free and AVG antivirus from www.downloads.com. This may take care of the bug. The boot sequence would otherwise have to be changed in the bios. Try hitting F8 upon boot to see if you can get to boot menu, depending upon what operating system you are using.
Go into BIOS by pressing F2 and configure the boot order to boot from
CD rom first save the changes and reboot your system.
Make sure you have a bootable disc. If it is an original system disc then it is if XP has been burnt onto the disc then it is questionable.
In the boot order the cd is second so it boots from the hard disk. You need to change that in the BIOS: press F1 immediately after start to access BIOS; there find the boot order (it's either directly in the main screen or it's in the Advanced section); in there put the cd first and the hard disk second.
And next time use a better antivirus, one that has a boot scan capability - the only one that is free for home use is Avast.
