Need help figuring this out. Complex!


Configuring your computer to boot from a USB drive allows you to boot into a separate operating system stored on a bootable USB drive.
This is handy when needing to troubleshoot a computer or access the hard drive without booting into the main operating system.
In order to boot from a USB drive, your computer's motherboard and BIOS must support USB booting.
If they do, then a simple tweak to the BIOS settings is all you need to do.

Shut down your computer and allow it to completely power off.
Insert your USB drive into an open USB port on your computer.
For ease of access, try to insert it into a front port if you have one.
Turn on your computer and enter the BIOS menu.
When your computer first boots, the manufacturer's logo will appear on the screen.
On the bottom of the screen is a note telling you which button to press to enter the BIOS.
Quickly press the button to enter the BIOS menu.
All manufacturers are slightly different, but some common buttons for entering the BIOS are F2, F10, F12, ESC and DEL.
If you are unsure, refer to the owner's manual that accompanied your computer.
Use the arrow keys to scroll down to the boot device menu.
It will be titled differently on different computers, but look for something like "Boot Order" or "Boot Devices."
Press the enter key to enter the boot menu.
Scroll down to "USB Drive" and set it as the first boot device.
Exit out of the BIOS menu and reboot your computer.
When your computer boots up it will boot from the USB drive first.

How do i repair the cmos for satellite l500? Bios update failed


To reset the BIOS read the information from this link. Although article is about removing BIOS password the second, third and fourth methods pretty much will bring the BIOS to initial factory settings.

I would suggest getting Hiren's Boot CD and use Kill CMOS to wipe the BIOS to the factory settings.

What is the process for hard resetting the bois


Sorry you are having trouble. I think you mean BIOS. The info in the BIOS is programmed into a ROM chip in the motherboard. It contains all the info the laptop needs to boot up and transfer control to the Operating System (OS). There is no reset for BIOS. We can reprogram BIOS with a special procedure if we need to but this does not happen often. I think you have an OS problem and I can help you with that if you need more info.

D520 setup locked, cannot change boot order or re-install os


here are 2 password type first 1 is bios password if tell me about your bios password it prompt when u powerup follow procedure below

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

And if u tell about windows password
Then when you power up the computer press F8 key then enter in safe mode then wait until it prompt for user passsword

then enter in administrator then if u able to enter then reset your password.
But if u set and forgot default administrator password then u should need winxp recovery disk.

Question regarding ur answer to my original problem...


Well, sorry if this reply wasn't as fast, it has an older email account attached to it (I will update that)

Look, I believe I said before that you would need to press F11 for Dell when it's booting (ino, before it has the Windows screen flash on)
This should tell you that you have a Dell as you are booting in, but more importantly, that will show you the BIOS, which is the computers system for how to start up the computer (as opposed to Windows) which should be installed by Dell in their computers before Windows is Installed.
Basically the factory programming.
Now, as far s 'flashing the BIOS'
I't means that you will install the Factory Software for your computer that handles things like how your compute will boot...
Like CD first, then Hard Drive, etc.
Things that mostly you don't have to worry about unless your compute itself, as opposed to Windows is the root of the problem, or 'needs' an update.
Now, to be fair, it is the DELL programming designed specifically to help DELL hardware run.... But....
There is always an inherent risk when flashing the BIOS that it could, theoretically, do more harm than good.

That said:
Here are a couple of general links as I don't remember all of the details of your needs, but this would be links regarding DELL and what the BIOS 'is'

If this doesn't answer your question, please write back and I will give it more attention, just very busy tonight

You don't have to update your BIOS just to have it changed into English... It's all there, your problem is how to get into that change language area... Check your system manual I am sure you'll find what you need...
