Unmountable_Boot_Volume (Startup Recovery Disk isn't working also)

[kaserblade99]

Today, my computer started doing sth strange at startup so I force shut it down.
After, I continously got the BSOD and Safe Mode nor Startup Recovery would work.
Since this is the only Windows 7 32bit PC around, I got an ISO of a Windows 7 32-bit recovery disk and burned it into a CD.
When I tried using the CD, it would load the files and give me a blank black screen with a large cursor in the middle.

Help please.

P.S.: This isn't the first time this happened but the first time I haven't been able to fix it

Things I've tried so far:
All the Options in the Boot Menu
Startup Recover Disk (Windows 7: System Repair USB - YouTube)
Changing the boot priority with the disk
Restarting my PC a million times

Hi kaserblade99 and welcome to SF .

I advise you to backup important data if still possible, prior to testing the DISK.

   Warning

The Following Method Should NOT Be Performed On An SSD!

:ar: Testing the HDD:

1. Perform a Disk Check | Disk Check- Scroll down to OPTION TWO of the tutorial and use the /R switch in the CHKDSK command | chkdsk C: /R.
2. Then Post the Disk Check results following | This Tutorial.
3. Once back in Windows, download Crystal Disk Info and post a screenshot (multiple shots if you have more than one drive).
4. Download SeaTools for DOS if you don't want to use a CD to test the HDD you can use YUMI – Multiboot USB Creator to create a bootable USB (instructions are found at the bottom of both pages).
5. If SeaTools for DOS is unable to recognize your HDD:
6. Visit HDDdiag and follow the instructions | Or follow the instructions below.

If SeaTools For DOS does not recognize the drive;
Boot into the BIOS using the *Fx key.
Look for an entry called SATA Mode (or something similar), it should be set to IDE / AHCI.
It's probably set to AHCI which is why SeaTools doesn't recognize them in the DOS environment.
Set it to IDE then save and exit usually by pressing the F10 key.
Now boot into SeaTools and it should detect the drives.
Start the Long Test and let it run.
Upon completion don't try to boot into Windows as it will only result in a BSOD, go back into the BIOS
and change the SATA setting back to what it was in the first place.

• *Popular BIOS access keys.

Re-seat the sata and power.

Let us know the results.

Be more descriptive... whta strange things were happening?

Did you try "system restore" already (so go back in time)?
You did "startup repair" ... after running it, there is a text "view diagnostics report" click on it. What tests resulted in a statuscode not 0x0?
