Load FAIL SAFE defaults in BIOS

June 28, 2010 at 10:28:11
Specs: Windows XP
I keep getting an "unmountable boot volume" error and need to load the fail safe defaults in BIOS.

Forgive me if this is an easy question, but how the hell do you do that? I've read countless messages about hitting the f12, f8, f2 buttons on startup.

However, nowhere have I found the option to load the fail safe default.

What am I missing????

Hi there,

Normally you can ge into BIOS by pressing these keys after stating your system.


Try these keys and hope fully you will get into BIOS . Once in BIOS then you will find a option of Load defaults.

If you are unsuccessful then post your system make and model so we can find a sloution for you.

Best of luck

where are you getting your information that this is how you address an unmountable volume?

There is no fail safe in the bios. There is a default factory config with a few choices.

You just need to check that the hard drive is first in boot order and the system is seeing the drive [bios summary screen].

Then you go on to address the unmountable volume issue.

Thanks. No options are found anywhere to load defaults.

My computer is a Dell Dimension 4600
BIOS Version: A08

Do a google search for unmountable boot volume error and you will find dozens of sites that recommend this.

I have already tried booting from the installation cd and running CHDSK, but that didn't work either. It stopped at 50% and said that there were errors that could not be recovered.

FWIW: Most Dells will allow you to access the BIOS setup with F2 after power-up (and before any OS attempts to boot). If you can access it this way, verify that the machine is able to identify the hard drive. If so, then it may have somehow become corrupt...

the correct chkdsk command in recovery console is chkdsk /p
I would suggest you try again.

you don't fix anything with just chkdsk.

I believe you misinterpreted what you read concerning the error. If you were not playing with the bios/cable before the error then you are only dealing with file corruption/bad hardware.

Yep.... tried the chkdsk /p, and also chkdsk /r and received the same message.

One day my computer froze and I couldn't get anything to work so I just turned off the computer with the power buttion and ever since then I've had this problem.

Any other suggestions would be more than welcomed. As you can probably tell, I know next to nothing about this stuff, so break it down for me in the simpleist form.

sounds more like a pending disk failure if chkdsk couldn't fix the issue.

Data all backed up?

Download the drive manufacturers diagnotic utilities and run them to check the status of the drive.

Make sure cables are well seated and that you are not overheating.

Then do a repair install of xp to see if it can correct the boot.

How do i do this if I can't start the computer.

As far as data being backed up... no worries. This is just an extra household computer that has no data that's important. Just trying to get the computer to work again.

I'm looking at the BIOS setup screen now and there is no option to load defaults.

a repair install is started by setting the bios to boot the cd first then the hard drive. You would get a message similiar to "strike any key to boot from cd' which will start the xp install.

You already wrote:
"I have already tried booting from the installation cd "
so I have to assume you know how to do the above.

How about booting up in the installation cd again, go into recovery console again and then run the commands fixmbr and fixboot. See if this doesn't get you operational.

Otherwise diagnose the disk and then if found OK proceed to the repair install of xp.

yep... tried fixboot and fixmbr.... and nothing.

What is a repair install? Would I lose all the data on my computer? As stated, the data is not that important, but I'd like to keep it if possible.

There is this really cool feature on the internet called seach.

Amazing what happens if you put in "repair install of xp"

A repair install refreshs the OS system files to install defaults which means you need to run all the updates but it leaves your data/apps intact.

You need to test the drive first. It may not be able to contain a master boot record due to platter surface failure.
