Windows 10: Need help with operating system

Hi

I had put an operating system on a flash drive a while back

I have a question once you download it to another computer does it take it off the flash drive

or can it be used again?


Also when you don't have an operating system how do you install OS using a flash drive from the boot


Thank you

Tim

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.
