Microsoft Windows 10 (64-bit)

I inadvertently made my BOOT partition (first partition) on my disk inactive by making the second partition (containing the operating system, applications and data) the active one. So now my laptop will not boot, and I cannot get into my operating system (Windows 10). Is there a way to revert to the old setting ?

 

BIOS vendor is Insyde (version F1.C). Setup utlity is InsydeH20, revision 3.5. Is it, by the way, possible to get newer versions of these ?

 

Kind regards,

Arild Dyrseth

Hi,

 

Try the following.

 

First of all, use another PC to create a bootable Windows 10 DVD or USB Flash Drive via the following link.  Under the section 'Need to create a USB, DVD or ISO', download the Media Creation Tool.

 

http://www.microsoft.com/en-us/software-download/windows10

 

Once you have this, run the tool, select 'Create installation media for another PC', then select the language, edition of Windows 10, and the 64bit option.

 

Follow the rest of the prompts to create this and then click Finish when completed.

 

Boot your notebook from your Windows 10 installation media as follows.

 

Insert the Windows 10 Installation Media and Shutdown the notebook.

 

Tap away at the esc key as soon as you press the power button to enter the Start-up Menu and then select the Boot Options Menu ( f9 ).

 

Use the arrow keys to highlight the CDROM or USB Flash Drive option, depending on which typre of media you created, then hit enter - if prompted to 'Press any key to continue....' - do so.

 

Select the ‘Repair your computer’ option, select Troubleshoot and then select Advanced Option.  On the Advanced options screen, select the Command Prompt - See option 1 on This Link for a detailed guide on accessing the Command Prompt.

 

Once you have launched the Command Prompt, do the following:

 

Type Diskpart and hit enter.

 

Assuming your installation is on disk 0

 

Type select disk 0 and hit enter.

 

Type the following commands, hitting enter after each one.

 

list partition

 

select partition x    ( where x is the Boot Partition number )

 

active

 

exit

 

exit

 

When complete, remove the bootable Win 10 media and try rebooting the notebook.

This worked flawlessly.  Thanks a lot DP-K.

 

A somewhat linked issue is: I suspect the BOOT partition to reside on a part of the disk surface that might have been damaged. Is there a way to move the entire BOOT partition to an unallocated part of the disk ?
