Hi friends,

I went into my laptop for the first time in a month last night, and my cursor froze in my Windows XP Professional, so I turn it off by way of the power button. When I turned it back on it went to the screen that says Safe Mode, Safe Mode Networking, Last know configuration that worked, etc... I tried all of the options and every one of them have the same thing happening. None of the options work. After it goes to load windows I get this green message flash for an instant (I caught the error message by way of my video camera)it says "Unmountable_Boot_Volume" (as seen in the attachment below) then my computer repeats these steps over and over again.

What should I do?

Technical Information:

(***STOP:0X000000ED" (0x8AD0FC30, 0xC0000185, 0x00000000, 0x00000000).

Here's what Microsoft has to say. First step would be to run chkdsk /r from the recovery console
http://support.microsoft.com/kb/555302

The error can be caused by a bad drive, a bad drive connection / cable (unlikely in a laptop), or a bad boot.ini file.

I followed these instructions below, however they did not work for me:
Download and burn the following ISO: http://www.thecomput...om/files/rc.iso
Boot to the CD and you should be presented with a recovery console.
From the recovery console type the following command and hit enter:
chkdsk /r



When I go "Boot to cd", as in the instructions above, the cd loads but I get the same blue screen problem message that is in my attachment, except this message does no longer say "Unmountable_Boot_Volume". Here is what it now reads now under the Technical information listed below.

Technical Information:

***STOP: 0xoooooo7E (0xC0000005, 0xF748E0BF, 0xF778DA208, 0xF78D9F08)

*** pci,sys - Address F748E0BF, base at F7487000, DateStamp 3b7d855c

Funny...I don't see the instructions you quoted...in the documentation which Allan linked to.

For Your Information .

There is an alternative method of creating a bootable disk which may assist you, see comments by Andrew at http://www.bleepingcomputer.com/forums/topic380303.html .

Sounds like its a Hard Drive or Memory Issue. Lets start with the easier of the 2. Are you comfortable with replacing the RAM in your PC? If you are, try re-seating your RAM. Pull all the sticks of RAM out and place only 1 back in. Then try restarting the PC. If that doesn't work, try the other stick of RAM in the same slot. If it still doesn't work, repeat the steps with the OTHER memory slot.
NOTE: Be sure you are STATIC FREE before touching the RAM sticks. A static shock discharged inside the PC will turn your PC into no more than a door-stop.

If this still doesn't fix the problem, we'll need to test your Hard Drive. Could you look and see what brand your current Hard Drive is? (ie. Seagate, WD, etc.)

Sorry Louis! I relayed info to Allan that I picked up from a member from another site, which did not work for me. I did not know of those rules in the for your info link in your post. I just burned a cd from the other link you gave me by Andrew and will try it in my sick computer now. I will post back about what happens. Thanks to both you and Allan for the info.

After the ARCDC cd that I created by way of Andrew thread loaded on my sick pc but I now received another error message listed below:

A problem had been detected and windows has been shut down to prevent damage to your computer.

If this is the first time you've seen this error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly
configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Technical information:

*** STOP: 0x0000007b (0xF78D2524, 0xc0000034, 0x00000000,0x00000000)

System manufacturer and model?

Are you saying that you actually ran the chkdsk /r command...or that you could not run the chkdsk /r command because you never got that far?

Dell Vostro 1520

That message in my above post is now coming up making it unable to do anything, so I could not run the chkdsk /r command because I never got that far.

I would say that it's time for you to run the Dell Diagnostics package.

STOP: 0x0000007b (0xF78D2524, 0xc0000034, 0x00000000,0x00000000) Many users with this error...were either trying to reinstall Windows or reported hard drive problems.

I disagree that you can make that diagnosis simply from the error code. In my experience, RAM can cause any error code, regardless of what the error code states is the problem. Re-Seating the RAM is a very quick and easy diagnostic. If it solves the problem, it saves hours of diagnostics. If it doesn't, you've spent 5 minutes and are sure that its not bad RAM.

Is there a charge for this diagnostic package from Dell?

I have never known Dell not to charge an arm and leg for anything they give you.

Louis,

I tried what it says to do in the link you provided in your post, and I got the following message when running the diagnostics:


Error Code 0146
Msg: Error Code 20000-0146
Msg: Hard Drive 0 - self test log contains previous error (s)
The given error code and message can be used bu Dell Technical Support to help diagnose the problem?
