Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.

If it's a Dell computer...
Go here for how to find the Service tag "number":
http://support.dell.com/support/top...

Tell us what it is.

If it's a HP or Compaq computer.....
Go here:
http://partsurfer.hp.com/search.aspx
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.

If it's a Lenovo computer
Find your specific Product number and tell us what it is:

The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
.........

Your problem has nothing to do with the bios (unless you flashed the bios with the wrong bios update or something went wrong while flashing it), or those settings in the bios. Enabling the shadowing for those two things merely allows the computer to take a little less time to load the bios code, and for it to improve your video perfomance a bit.

Describe what your symptoms are, in as much detail as you can come up with.
........

If your computer is getting no video at all while booting BEFORE Windows attempts to load (assuming you have the monitor plugged into the right video port if you have a desktop computer if you have more than one), you probably have a hardware problem with your computer,

or a lot less likely, if the computer is booting fine, if it's a desktop computer you may get no video at all, if your mboard has onboard video, you're using a video card installed in a mboard slot for the monitor, the main chipset supports Hybrid video, but the video chipset on the video card in the slot is not one of the ones that supports the Hybrid video feature (that problem is easily fixed).
..............

If this is a desktop computer...

If you are ALWAYS getting video while booting BEFORE Windows attempts to load, but NO VIDEO AT ALL in Windows after it is supposed to load, that problem is easy to fix.

( To get Windows into Enable VGA mode.....
- Remove all bootable CDs or DVDs in drives
- Press F8 repeatedly while booting the computer, don't hold down the key
- when the (Windows) loading choices menu appears, choose
Enable VGA mode.

Some computers have a different use for pressing F8 while booting. E.g. a menu may pop up that has the devices listed on it you can boot the computer from.
If you see that, read what it says on the screen and find the key you press to get out of that menu, e.g. Esc.
Press that key, then immediately repeatedly press F8 - the (Windows) loading choices menu will appear - select Enable VGA mode.)

Well normally those are turned off, they aren't needed on newer computers. I have a sneeking suspition you've been in the BIOS messing around with settings.
If this is true, go back into the BIOS and find the option to reset to defaults.
When did Windows stop working?

"Well normally those are turned off"

Newer bioses often don't even mention shadowing, but for bioses that do, usually at least shadowing the bios rom is enabled by default, not disabled, and in some bioses both of them are enabled by default.

It certainly does no harm to enable both of them - either it helps a bit or it has no effect, depending on the operating system.

Your probem can be caused by....
- you don't have the network boot option in the correct place in the Boot Order or similar settings in the bios Setup

- you DO have that set correctly but
- the bios is not detecting your hard drive at all
- or - the bios is detecting the hard drive but it's not finding that it's bootable (has an operating system installed on it)

See Response 1:

...........

If it's a new hard drive, or a used hard drive that had all it's data deleted or at least an operating system on it deleted, it's not bootable.

If two hard drives can be installed on this laptop and you DO have two of them installed, the bios WILL NOT try to boot from anything else if the first hard drive it detects by default, or is custom set to detect, is not bootable. In that case, go into the bios and find the list of hard drives - that's often near the Boot Order or similar settings - they are usually listed by their model number - the bootable drive must be the first one in the list, SAVE bios settings.

Shadowing of BIOS and/or Video BIOS does little if any good nowadays. OSs don't use the BIOS once they have booted.

Having said that, it doesn't sound to me as if this is anything to do with your problem. Your OS isn't being found, either becasue it has been corrupted or because the hard disk isn't working. Do you have a XP install CD?
