View Full Version : I Urgently Need Tech Advice: Potoroo, Minoos, etc.

I brought my daughter home from university today for her reading week. Her laptop fails to boot completely; it boots to the notification screen: Press F8 for safe mode, last known good configuration, etc. Says it stopped to prevent system damage? No matter which option I select, the boot process begins [I see the Windows logo] and then I get a blue stop screen with the message Unmountable_Boot_Volume and Stop 0x000000ED 0x84B6EE30 0xC000006 0x00000000.

There is connectivity between the hard drive and motherboard, because the boot process begins and I see the Windows logo, then it halts at the blue screen. I need advice as to my next step. I have the installation and recovery disks, if all else fails. I'm considering trying fdisk /mbr as my first step, but I really need more expert advice than my own limited tech skills.

My daughter has complained that the system shuts itself down with no warning. We had it in to the shop for warranty work; they cleaned it inside, something about the heat sink, etc. I suspected overheating. After a few months out of the shop the same problems are occurring again. Still under warranty... The system is a Toshiba Satellite A70, Pentium 4 3.06 GHz, 1 GB of RAM, Windows XP Home SP2.

I know there are some good hardware people here; Potoroo and Minoos come to mind, as well as Bunker Rat, but haven't seen him here recently. Thoughtful advice appreciate. Thanks, gang.

"Unmountable Boot Volume" Win XP

Software KB
kb# SW00014
When booting up to Win XP you may get a error that reads "Unmountable Boot Volume". This is probably because your boot.ini file is messed up.

So, what do you do about it, panic and try to mount your boot in your computer...... No that is probably not a good idea.

You can boot to the XP cd and when you see the Welcome to setup press the letter R
You will get a dos prompt
Then type "chkdsk /p" without the quotes and hit enter
When that is done type "fixboot" and hit enter
"Y" and enter at the prompt
Then type "exit" and hit enter
The system will now reboot into Windows

If for some reason that don't work for you, you can boot to the recovery console like above and...
Type "chkdsk /r" then enter
When done type "exit" and hit enter.
This will take longer, but the system should boot back into Windows.

I have tried several times in a row to get into the repair console but the machine just kept shutting off. I seriously suspect overheating [again!] and have let it sit for about an hour. I'm going to log off from here and give it another go. I have to do this because where I am conducting this work I only have enough power outlets for one laptop at a time.

This laptop is in bad shape. I can't even get it to run long enough to run the repair console commands. I've given up for tonight; gonna let it cool off overnight and try again tomorrow morning. I'd like to get it going long enough to recover the drive and my daughter's files before I take it back to Best Buy. I swear, I've had two Toshibas and one HP laptop, the next laptop is going to be a Dell or Alienware.

Progress report: After several attempts last night to try to get somewhere, I gave up for the night. Started again this afternoon; put the laptop on a Lapcool4 cooling mat. The LC4 is a great mat, with two builtin fans, a four port USB bus and card reader. I made sure there was plenty of air circulation underneath and after several aborted attempts and cooldown periods I was finally able to get it going, use the chkdsk /r command in the repair console and get Windows going. Over several sessions I was able to recover all of my daughter's files, as well as run Norton Win Doctor to fix a few things. I can't keep it running long enough to run antivirus and antispyware sweeps. As it is still under warranty I am returning it to Best Buy for the second incident with overheating. The Lapcool helped me to keep it running for longer than it normally would, but it still shuts off without warning. The battery doesn't seem to be the problem, as it remains cool to the touch and I had the same problem with the battery removed. I ran it while hooked up to a UPS. However, the underside of the case gets hot to the touch, which indicates to me that interal overheating is the suspect. Anyhow, Best Buy can deal with it as it is under warranty, but I have little faith that they will get it fixed for good. I think I'll be getting in touch with Toshiba and doing some research to see if this is a problem with this particular model or if we just have a lemon.

Again, I appreciate the advice you folks have given me.
