Unmountable_boot_volume, STOP: 0x000000ED (0x8AFAE368, 0xC0000006, 0x00000000, 0x00000000) Disable BIOS memory options

Help please. My DELL Inspiron 6400 laptop, XP home edition - Unmountable_boot_volume, STOP: 0x000000ED (0x8AFAE368, 0xC0000006, 0x00000000, 0x00000000) blue screen message.

Also - disable BIOS memory options such as caching or shadowing.

When starting in safe mode - STOP: 0x000000ED (0x8B01A368, 0xC0000006, 0x00000000, 0x00000000)

I am not tech-savvy at all.  Having read the thread my question is: do I need to do anything differently from others when following the bootable XP recovery console CD fix instructions? At what stage do I disable BIOS memory options?

That message indicates a problem with your NT File System (NTFS) and those kinds of problems can happen after a power interruption, plug pulling, using the power button, aborted restart, ungraceful shutdown, etc.  Have any of those events occurred?

All that boring text on the Blue Screen of Death (BSOD) page is mostly just boilerplate from XP and is the same (or close to the same) for just about all BSODs.  Interesting to read one time in your life, but generally boring and unhelpful and the best information for troubleshooting a BSOD is in the STOP message and the line or two that sometimes comes under it.

It is extremely unlikely that you need to disable BIOS memory options or any of that stuff you read on the BSOD, so I would not start there. 

What you need to do for that error is run a check disk with error correction to see if it will straighten out the file system - and you may need to run it more than once.

If you have a genuine bootable XP installation CD, you might get it to work from there but since most people don't or are not sure what they have, you can make a bootable Hiren's CD and run your chkdsk with error correction from there.  The Hiren's Boot CD is also a good weapon to add to your troubleshooting arsenal.

Here's how:

Make yourself a Hiren's Boot CD which you can download from here:


The ZIP file is large, so the download will probably take a little while to complete bit it is worth it.  Then unzip the download to extract the Hirens.BootCD.ISO file that will be used to create your new bootable CD.

Creating a bootable CD from a .ISO file is not the same as just copying the .ISO file to a blank CD.  You have to use software that understands how to burn a .ISO file to a CD to create a bootable CD.

In the Hiren's ZIP file are the BurnToCD.cmd file that you can double click to launch it, but I have never used it and prefer to use ImgBurn.

If you need a free and easy CD burning software package, here is a popular free program:


When installing ImgBurn, DO NOT install anything from UniBlue or the Ask toolbar (never install the ASK toolbar for anything).

Here are some instructions for ImgBurn:


It would be a good idea to test your new bootable CD on a computer that is working.

You may need to adjust the computer BIOS settings to use the CD ROM drive as the first boot device instead of the hard disk. 

These adjustments are  made before Windows tries to load.  If you miss it, you will have to reboot the system again.

When booting on the Hiren's CD you will see a menu of options.  Choose the Mini XP option.  Then it will appear that Windows is being loaded and you will be presented with a desktop that has the look and feel of the Windows Explorer interface you are already used to using.

Remember:  You did not boot on your hard disk - you booted into the Hiren's desktop.

One way to check the disk for errors is to open My Computer and right click your afflicted drive and choose Properties, Tools, Error-checking, Check Now... put a check mark in both the boxes and then Start.

Sometimes that doesn't work, so you can also click Start, Run and in the box enter:


Click OK to open a Command Prompt window and enter the following command (assuming XP is installed on your C drive)

chkdsk  c:  /r

This disk checking can take a long time (perhaps several to many hours) depending on the size of the volume, the amount of data on the volume and what the disk checking finds to do.

Let chkdsk finish and correct any problems it might find. 

Depending on the the speed of your system, the size of the volume, the amount of data on the volume and what chkdsk finds to do, it may take a long time for chkdsk with error correction to complete (several to many hours) or it may appear to be 'stuck'.  Be patient.  If the HDD light is still flashing, chkdsk is doing something so don't interrupt it.  It will finish eventually one way or the other.  Keep an eye on the percentage amount to be sure it is still making progress.  It may even appear to go backwards sometimes.

You may have to run the chkdsk  /r  it more than once.

Did this solve your problem?

Sorry this didn't help.
