Boot failure error 0xc000000f win7 | cannot auto-repair

Hi there, i went on break for about 2 weeks, and upon starting up my machine started getting a bsod for unmountable boot volume.
tired to restart in safe mode, but none of the options were working [when attempting safe mode, would load as far as file classpnp.sys], selecting anything would just loop back to the same bsod over & over.

i had a recovery tools/disk on USB [don't have any disc drives on this machine],
so plugged that in & tried running startup repair, but it fails. this is what i get:


after that fail, rebooting my machine no longer yields the bsod mentioned above,
but rather this lovely boot failure error 0xc000000f:


so tried the recovery usb again, this time with command prompt as the recovery tool & ran some stuff there,
below are my results...

- diskpart output:


- bcdedit output:



not sure where to go from here. i've been trying to fix this for 3 days now [spent NYE at home trying to fix this even ].
am hoping won't have to re-install OS cause it's been a while & i don't have the disk anymore [would probably have to install via usb shenanigans], any suggestions greatly appreciated

p.s. sorry for the terrible images, taking them all with my phone.

That particular BSOD is almost always caused by damaged file system on "C:" partition. The corruption in turn is commonly cause by HDD surface defects ( otherwise called bad sectors ).

The first screenshot you posted also shows Problem signature 07 : No OS installed which means "Startup Repair" can't locate a valid Windows installation. This can also caused by damaged file system. If file system is corrupted and unreadable, the recovery environment will fail to detect whether Win7 is installed or not in the system.

( DISKPART also identifies the 232 GB partition as RAW - which means unidentifiable ).

I would recommend ;

1. Backup any important data to an external medium.

Emergency Kit - save your files from a dead OS

If file system is severely damaged, you may not be able to copy the data to an external medium. In that case, please proceed to step 2.

2. Diagnose and confirm the health status of hard drive.

Once important data are successfully rescued, follow SeaTools for DOS and Windows - How to Use

Although you have a WD disk, "Seatool" supports diagnosing it. Make sure to plug the HDD to a SATA 3gb/s port and set SATA mode to IDE emulation in BIOS before running the "Long" test.

Once the test is finished, report back whether the test detected failures or not (or post a screenshot of the test result ).

Same here. What the hell is wrong with rebooting the pc. I don't have the installation cd or whatever, just don't know what to do.

volume D in you screenshot (the OS disk with win7) has turned RAW. windows doesn't know what it is. Try in "command prompt":

Code:
chkdsk/f d:
what happens?

Code:
diskpart
select volume D
detail partition
detail volume
exit

Hi Anshad,

after several restarts got this additional message:

CHKDSK has the bad habit of deleting partially corrupted data and this behavior may cause data loss if there are lost of bad sectors. That is the reason why i don't suggested running CHKDSK directly without knowing how much bad sectors are there ( Seatool usually report the number of defects it founds ). If there are no bad sectors/only a few, usually it is safe to run CHKDSK.

Since Mint refuses to run on your system, i would suggest "Puppy" which is only 160 MB in size : http://distro.ibiblio.org/puppylinux...-5.7.0-PAE.iso

What do you mean by saying "partitially corrupted"??? If sectors are faulty,... the file the sector belongs to is corrupted. So useless. At least for system files.
