The drive where Windows is installed is locked. Unlock the drive and try again.

Hello,

I am running windows 8.1 on an Asus N551JX, with a 128GB SSD + 1TB HD (devided in 2 partitions 500+500)

After a Microsoft office 365 update this afternoon, I have noticed a some sluggish and lagging behaviour on office or/and maybe the explorer. Taking a while to highlight and open the documents, freezing. I then decided to install all the windows optional updates available. During the download and installation I have tried to open another document. With the document opened the PC just froze up. Some message with the sad smile ":(" in the end came up and the windows restarted. After that it won't boot up again.

I have tried a recovery media I made a couple of months ago. But the Start-up repair says "Start-up Repair couldn't repair your PC". If I try Refresh your PC it tells me "The drive where Windows is installed is locked. Unlock the drive and try again.".

I have a 128GB SSD HD wherein the windows and a few games were installed. 

On the BIOS boot up sequence I can not seem to find the SSD. And in the Troubleshoot menu of the Media, If I click "system Image Recovery" and browse to find a driver, the C: drive is now one of the partitions of my normal 1TB HD. Can't find my "old" C: drive where the windows is installed. Is the SSD dead?

Help please! I need my PC for my work!

Hello Duarte,

Thank you for posting your question on Microsoft community.

I would like to know some information about the issue so that we could help you better.

Did you make any hardware changes to your computer prior to the issue?

I appreciate you for providing details about the issue and your efforts towards resolving it.

This issue may occur due to corrupt Windows startup files.

As startup repair failed, I would suggest you to run Bootrec commands in the command prompt from Windows recovery environment  and check if it helps. Please follow these steps:

a. Do one of the following, depending on whether you have installation media (such as a DVD or USB flash drive):

- If you have installation media for Windows 8.1, start (or boot) your computer from the installation media. Insert the DVD or USB flash drive and restart your computer. If you see a message asking you to "Press any key to boot from DVD", do so. If you don’t see the message, you might need to change the boot order in your computer's BIOS settings so that it first starts from the DVD or USB. When you see the "Install Windows" page, click "Repair your computer" to start the Windows recovery environment.

- If you don’t have installation media, use the power button to restart your computer three times. This will start the Windows recovery environment.

b. In the Windows recovery environment, on the "Choose an option" screen, click "Troubleshoot".

c. Click "Advanced options" and then click "command prompt".

d. In the command prompt, type the following commands one by one and press Enter after each command.

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

You may create Windows 8.1 installation media using the following article:
Refer:
Create installation media for Windows 8.1
http://windows.microsoft.com/en-US/windows-8/create-reset-refresh-media

I hope this information helps.

Please do let us know if you need any further assistance.

Thank you

Hi Ratandeep,

Thanks for trying to help me.

I have not made any hardware changes. Just updated office 365 and I was trying to run the optional windows updates when it froze and never booted up again.

The first two commands say "the operation completed successfully".

The third one (bootrec /rebuildbcd) says "Total identified Windows installations: 0 " "the operation completed successfully" 

Tried to restart the system but it still wont boot up normally.

Next step?

Thank you

Duarte

Hi Ratandeep,

Tried to follow Vijay B, but here is what I get:

X:\sources>bcdedit /export c:\bcdbackup

The store export operation has failed.

The requested system device cannot be found.

I have also tried with d:\ instead, but same message comes up.

Thanks for all the help!

Just to let you know some additional info.

I have tried another approach in the meantime. I have swapped current 1TB hard drive (which only has files) with a spare one I had from my old laptop, to see If I could access the SSD hard drive (with the original windows 8.1 which we want to correct the installation of) from a new and clean windows 8.1 installation using the USB recovery media.

In other words: I have done a clean install of windows 8.1 in my old hard drive. Everything went alright during the installation.

Result: the SSD does not even show up in the device manager. And some unknown devices the windows can't find the drivers even connected to the internet.

Does this help? (I hope I haven't made it worse to solve the original problem)

Thank you!

Hello Duarte,

Thank you for the reply.

I appreciate your patience and efforts.

If Windows boots, I would suggest you to run check disk on the SSD hard drive to find and fix any errors which may be causing this issue. Please follow these steps:

a. Press Windows + X keys and click command prompt(admin).

b. Type the following command in command prompt and press Enter.

chkdsk /f <drive letter:>

Where drive letter is the letter assigned to SSD.

Note: While performing chkdsk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost.

Please keep us posted.

Thank you

Duarte Mauricio,

whilst I cant say for certain your problem is the same as mine, I had virtually identical problems with one of my PCs that had a boot SSD. First it slowed down a bit, then it froze then it refused to boot. I had the same message from 'startup repair', and even the 'locked' message. UEFI/BIOS also would sometimes not see the SSD, occasionally it would but usually not, and my internal HD ( was E: drive ) had become C:.

So the symptoms are very similar if not identical.

In my case, the SSD had failed :(

The PC was only about 6 weeks old so I packed it up and it went back under warranty.

Hope its not the same in your case, but do you have a means to test the SSD somewhere else, another PC perhaps? or if its a new(ish) PC I'd contact the supplier.

Hi Ratandeep,

How can I run check disk on the SSD hard drive if I do not know its letter?

The SSD hard drive is not even detected.

Thank you very much
