Windows 10: missing operating system problem

Hi there. I am trying to fix my computer. It has an error while i start the computer showing "missing operating system". I don't know what is going on. I used a windows 10 installation media to boot my pc. And i am trying to see what is going on with the partitions or the MBR etc. if i open the command prompt and type diskpart and then list volume, the following partitions on the table appear. Why in the volume 1 the file system is RAW ? How can i fix that ? ALso my hard disk size is 1000 GB. So volume 2 has the operating system and where are the rest ? Volume ###LtrLabelFsTypeSizeStatusInfoV

After updates Windows 10 says "Missing operating system"

I have the same issue, and I followed your suggestion steps. After that, I can see C: drive, and Windows folder is there.

Then I rebooted the computer. But I still have the missing the operation system issue. Any suggestions?

Thanks.

 

operating system language problem

I have upgraded my windows 8.1 to windows 10 in August 2015. Since then I am struggling to change the operating system language but not able to do it as I cannot understand Dutch in which the system got upgraded. I bought this lenovo laptop from Netherlands,
so it has default operating system language as dutch. I tried many tips suggested online to change it but not able to change it. Please suggest how can I get rid of these problem. I want to have administrative language as English. Please suggest step by step
procedure. It is even difficult to figure out which is pc setting option, recovery option or update option in dutch.

Thank you.

 

Error: "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system"

Hi Stephen,

I realize the inconvenience you are facing in accessing the operating system. Now that you have me with you let me take care of this.

Do let us know if you are able to see Windows 7/ Windows 10 operating system while rebooting the device?

As you are unable to boot the operating system, this issue might have occurred when the boot files are missing or corrupted.

I suggest you re-built the boot rec by following the below commands and check if it helps.
You will have to use Windows 10/7 installation media to follow the steps to boot into Recovery Environment and try to rebuild BCD.

Step 1: I suggest you to create an installation media for
operating system using the media creation tool

If system boots to Windows 10:
Installing Windows 10 using the media creation tool

If system boots to Windows 7: Download Windows 7 Disc Images (ISO Files)

Step 2: After preparing the installation media, insert it hard reboot the device and follow the below:

• Boot into Windows Recovery Environment using the Windows 10/7 installation media.
• Click on Repair your computer.
  
• Click on Troubleshoot and in the Advanced options.
• Select Command Prompt. Type the following commands into the prompt and press Enter key after each command.

• bootrec /fixmbr

• 
  bootrec /fixboot
  
• 
  bootrec /scanos
  
• 
  bootrec /rebuildbcd
  

5. Restart the computer.

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.

Hope it helps. Reply to the post with an updated status of booting the operating system for further assistance.

Thank you.
