safe mode, command prompt, last known good configuration, safe mode looks
like its going to start but it doesnt, just keeps going to the blue screen
instead of login screen, I pressed ALT+F10 to access D2D recovery but nothing
happened, dont even know what it is meant to do,but thught it was worth a
shot,pressed F8- directory services restore mode- message says 2 this system
is booting into safe mode-directory services repair" then nothing , back to
blue screen, he has no windows cd to reinstall, any ideas as to how or if i

0x000000ED: UNMOUNTABLE_BOOT_VOLUME
The kernel mode I/O subsystem attempted to mount the boot volume and it
failed. This error also might occur during an upgrade to Win XP on
systems that use higher throughput ATA disks or controllers with
incorrect cabling. In some cases, your system might appear to work
normally after you restart.

Try booting with all hardware peripherals, except keyboard, mouse. and
monitor, disconnected.

If you have important data files to be recovered you need to do this
before trying to fix the computer! Do you

What is the computer make and model? Do you have access to a second
computer? What make and model is that computer?

What is the hard drive make and model?

What is the BIOS -I am wondering whether beep codes might help?

You might try checking the Boot progress against the information in
these links to see if you can identify how far it gets

Hi and thanks for the reply, the laptop is acer travelmate 2310-hard drive
model samsung MP0402H - HD serial no. S03WJ20Y711176- system BIOS version
3A22
the exact message on the blue screen is:-UNMOUNTABLE_BOOT_VOLUME stop:
0x000000ED(0x81AD5E30,0xC0000006,
If this is the first time you have seen this error screen, restart your
computer,if this error happens again, follow these steps- check to make sure
any new hardware or software is properly installed, if this is a new
installation ask your hardware or software manufacurer for any updates you
might need
if problems continue disable or remove any new hardware or software, disable
BIOS memory options such as caching or shadowing

I cant cant into safe mode to do anything, have been to bios and cant see
any reference to caching or shadowing ,this pc was given to someone by my
niece only two days ago and it worked fine when she gave him it, he only
added a device to connect wirelessly, i think he may have got a virus
visiting iffy sites , the first link you gave me i had been to already and
printed it out, it says the cause is the file system is damaged and cannot be
mounted or its the wrong connector cable, it must be the file system because
the cable to connect hasnt been changed and it tells you what to do but i
cant do it as i DONT have the original cd, the product key is on underside of
laptop but we dont have the actual cd,when i start pc , the acer logo comes
up and windows starts to load but then it goes straight to bluescreen , then
goes off and the whole thing starts again


I do have access to another computer, it is a packard bell ixtreme X2711
windows vista home premium
the one im trying to fix is windows xp home edition
there is no important data on the laptop, im going to have a look at the
other links you provided .
 
Just to add, when i switch pc power on, the first screen is acer logo, then
it goes to black screen with a message apologizing for the inconvienence
windows did not start successfully a recent hardware or sofware change may
have caused this, then it gives you the choice of safemode-safe mode with
networking- safe mode with command promt- last known good configuration,
choosing start windows normally or last known good configuration looks like
its going to start windows but only for a few seconds then goes straight to
the blue screen, all safe mode options load up to
windows\system32\drivers\mup.sys then go to blue screen.

monitor, disconnected.

Did you try this suggestion?

The problem could involve a USB device.

The laptop came to me with a wireless card attached at the side, i removed
this , there are no usb devices connected, i tried running the acer D2D
recovery( press alt+ F10 on the acer logo splash screen) but it just keeps
going to the windows screen telling you windows did not start successfully ,
this could be due to a hardware or software change. i
 
If you have access to another PC I would download and burn the
vendor diagnostics tool for your particular brand hard drive. For
example Seagate has "SeaTools". The tool is usually offered in an
..Iso format and your can burn that using ImgBurn. This creates a
bootable diagnostic disk. On 1st run you use the "Short Test" to
determine if the drive has ( or is in the process ) of failing. This test
will also read the SMART table and report if the drive has reached
or exceeded any of failure counts.

The fact that the recovery process doesn't start/load would also
indicate you have a physical drive issue.
 
Hi McCarty

Ruby's computer stops at mup.sys I have two normal boots from my own and
another to look at. Both only show loading drivers from the system 32
driver folder after mup.sys. Whilst not ruling out drive failure doesn't
reaching mup.sys suggest that the drive has been accessed OK? Many
drivers after mups.sys are usb drivers, which is why I suggested
disconnecting hardware peripherals. I haven't yet finished examining
drivers which normally load but two drivers seem to load very soon after
mups.sys.

intelppm.sys -Processor Device driver. I am not too clear as to it's
purpose but I suspect disconnecting hardware is not a solution. I think
you can use the Expand command from the Recovery Console and get a
replacement driver from the driver cache. I only found this out an hour
ago and I am not familiar with how to use the Expand command.

nv4_mini.sys -Nvidia driver linked to graphics -NVIDIA Compatible
Windows 2000 Miniport Driver. I am wondering whether the Safe Mode
option -Enable VGA bypasses this driver?

Something else I would like to know is if a driver cause the boot to
fail does it stop at mups.sys or at the driver before the one causing
the problem. Of course you need to disable Automatic Restart for the
boot to stop.

It's always hard to narrow down a boot failure. It may not be that the
drive is failing but has "Logical" not physical errors. I've seen a number
of cases where a Chkdsk C: /R will resolve this type of problem. I just
recommended the disk analysis as a way to verify the physical disk is
OK as a starting point.
 
Ok we managed to get the windows xp cd , worked using the product key from
this laptop, got xp loaded again ,took all day to get the updates and
antivirus etc back on it, thats when i think i discovered what he had done
wrong, when i went to install his wireless notebook card he had added, i put
the cd in and there was a bit that you had to choose where the file was to be
taken from or soemthing like that, and there was a choice already
highlighted, but it wsnt correct, you had to navigate to a list of drivers,
there was choices for windws 2000,98,cant remeber what else but xp was there
too and you had to choose that , i think hes just clicked on the higlighted
choice and the wrong drivers got loaded, completely buggered up the system,i
now have it all sorted and ive reinstalled the acer management thing that was
missing too, that was why the alt+F10 didnt work, the program was missing,
thanks for all the help , was begining to think it was a lost cause
 
Ruby

That's a good result. Not a lot of Unmountable Boot Volume problems end
up with a good result and also knowing what caused the problem. Well
done.
