Re: unmountable boot volume blue screen error

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.

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.

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.

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

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

Did you try this suggestion?

The problem could involve a USB device.

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.

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 .

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
