Unmountable Boot Volume

Hi,

I have a dual boot XPS laptop with ubuntu and windows 7. After some windows updates the laptop does not load in windows. We try all sort of options:

- Safe mode crashes
- Last good known configuration the same
- Repair from cd the same
- Load with boot cd rescus in a linux environment - partition gets to 50% and gives error
- Connect with enclosure the disk and still partition not visible to get the data


We need a way to get it and get the data at least. Any suggestions?

This is the error we get on blue screen when we load windows partition

Interruption during application of update? Or is this an issue during the first boot after the update?
if you can boot the system into Ubuntu, you should be able to get the data off.

Boot off the DVD into repair console, and run chkdsk on the harddisk. Possible badblocks could cause this issue.
You should consider getting a new HD and clone the one you have.

Boot a linux CD and use ddrescue and save to an external drive. Then use GetDataBack for NTFS to get back your files from the windows partition. You can run GetDataBack on the image file.

Im guessing your harddrive might have a problem (defective sectors for example, and that therefore the system cant be bootet up after update as some files didnt got updated properly and/or filsystem gots damaged)

The imaging process will give you informations if there were defective blocks of the HHD while imaging.
Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Usually the media that comes with the new disk are good.  Ubuntu liveCd and using DD if=/dev/sd(current drive) of=/dev/sd(newdrive) bs=512. Though this can take some time depending on the size of the original.

When booting from the DVD, one of the trait option is the console, that is where you need to be to run chkdsk.  The other option is to pull the laptop HD and attach it to a desktop via USB or another hot (while the desktop is powered up) and run chkdsk that way.

Once the system boots, several HD vendor provide a tool such acronis disk image LE limited to the MMFgs drive being one of the HD SRC/clone dst. I believe most manufacturer of HDs SSDs include software dealing with getting/cloning the source onto their storage.

Easyus backup is one as well.  There are several other

i would hook the disk to a working system, or boot from a live cd
then copy the data
if however you keep getting the "unmountable boot volume" error, i suggest to run the disk manufacturers diag on it -and if it comes back clean, chkdsk
you find all the diags on the uBCD :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

The error you get indicates destroyed NTFS.sys driver for your XP partition. You need to run on system partition a CHKDSK x:/f command to fix it.
To perform this command you can slave the drive to another working PC or boot it from a DOS diskette (created with another XP installation) to command line interface and check there the partitions.

Agreed, the volume is unmountable and checkdisk will usually fix this, yes. Seen this often.
https://support.microsoft.com/en-us/kb/555302/ talks about checkdisk as the first possible solution, too. (Still applies though the article is for xp).
