    Unmountable Boot Volume with very limit resources to recover


    I have Windows 8 OEM pre-installled on SSD (hybrid drives: SSD and HDD = 750GB) which comes with the Vaio machine. Few days ago I reset the machine to its factory default setting from 8.1 to 8 (downgrading) due to the corrupted/error files on my HDD because it froze/locked me out - couldn't do anything at all apart from either leaving the auto disk repairing ran for days up to more than a week with no sign of completion OR a fresh clean install, I chose the latter one as I didn't have much time to waste on the system scanning. The only solution was to use "Vaio - Assist" button accessed to the UEFI settings >> F10 >> Reset all. That went well, I had the factory Windows 8, and then download, upgrade, and install all the essential softwares and drivers for Wins 8 and Vaio itself. I then again upgrade from Wins 8 to Wins 8.1 in preparing to upgrading to the Wins 10. Everything went well again from Windows 8.1 upgrading to Windows 10. Problem's occurred when I was about to create a partition for a Windows 10 recovery drive from the internal HDD. It didn't allow me to shrink the C drive in order to make a new partition for Wins 10 recovery drive but was asked me to perform the disk scanning first due to the files corrupted found. I used "chkdsk /f /r", it started to check after the next reboot and got stuck at the 11% for hours and then the system decided to shut itself down completely at that 11%.


    When turn on the laptop, the Windows blue screen with sad face welcomes me with this message "Unmountable_boot_volume". It hangs on this screen for a couple of minute and then brings me to this page:


    "Recovery
    Your PC couldn't start properly.
    A required device isn't connected or can't be accessed.
    Error code: 0xc0000185
    You'll need to use recovery tools. If you don't have any installation media, contact your PC administrator or PC/Device manufacturer.


    Press Enter to try again
    Press F8 for Startup Settings
    Press ESC for UEFI Firmware Settings"


    WHAT I DID TRY AND DIDN'T WORK
    1. F8 Startup Settings -> All the settings available on this page are not working. Bring me back to the blue screen of sad face loop.
    2. ESC for UEFI Firmware Settings -> Start or maintain your system [F10] -> After press F10, also brings me back to the machine restart and blue screen of sad face "Unmountable_boot_volume" loop. (This page on the normal working performance should have presented me with all the Windows tools: Reset, Advanced options with Command prompt, Restore, and etc.)
    3. Try recovery from Windows 8 disc (on the Wins 10) -> Disc reading sound for quite some time and then black empty screen. If left the disc inside long enough, it brings back the blue screen of sad face page.
    4. Try both UEFI and legacy boot with non seems to work.


    MY LIMITATION RESOURCES
    1. My only spare computer I have at the moment to download the USB recovery tools from MS is from the college library, where I AM NOT ALLOWED TO INSTALL ANY PROGRAMS on the machine which means I cannot retrieve the USB tools in order to try to fix the laptop.
    2. Friends also have limited access on their work PCs/laptops as well.
    3. Vaio machine is out of warranty and Sony stopped manufacturing the laptop line, not sure about support but I won't be paying any penny for the recovery disc as I am already have them but not working plus I am not sure whether the HDD is completely gone.


    Please anybody attach me the links and/or your answer to fix the laptop from the symptom described above because I cannot install any programs. I have 2 of 8GB USBs at the moment I need:
    1. Bootable Windows 10 Pro - 64 bit recovery tool files = All the files that should be in the bootable USB.
    2. Full Bootable Windows 10 64 bits international language version files on the USB.


    I deeply appreciate all your helps in advance.

    Can you download the W10 ISO from MSTechBench, mount it and copy all the files to your stick drive in the library?
    Tech Bench w10 iso

    Windows 10 ISO Download - Windows 10 Forums

    Windows 10 - Clean Install - Windows 10 Forums

    You can clean install W10 on a W8 machine and it will see the key in the BIOS and activate.
    With all your limitations, not sure how to help you determine if the hard drive is failing. I guess, if it is, the install will fail.

    1. I only have 8GB x 2 USB drives. Tech Bench requires greater than 16GB drive.
    2. I need all the useful related files for fixing in a ready downloaded form posted on Box/Dropbox/else and all must be bootable on USB.
    3. How to clean install when I have no access to Win recovery page plus Wins 8 disc not working either? Please guide.

    The TechBench ISO en-x64 is 3.9GB. I don't see how an international version could be >16GB?

    Mounting the ISO in W8, you can copy the files to the USB stick - no installation required anywhere. If W7, the 3rd-party tool 7-zip will mount the ISO for you.

    The USB stick will be bootable. Please follow the link I posted for a clean install above.

    I've just downloaded the file, college library using Wins 7 with a very high restriction, when I click over the ISO file in order to mount to the USB drive, there's WinZip fie installed on the public machine though. This limited access drives me mad and I have no other solution to mount the ISO file. Please advice further.

    So you have the ISO downloaded on a library W7 machine, and this W7 machine also has WinZip installed? Let me see if there are procedures for mounting an ISO with WinZip (I've never tried that). Hold tight.

    This W7 machine doesn't have any WinZip installed as I cannot find this program anywhere on the C drive.

    What options do you get in the box that pops up when you right-click the ISO file?
