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 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 (uefi) or USB Flash Driver ( uefi ) 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 list volume and hit enter.

 

Look for the partition that’s formatted as FAT32 and select it – ie if it’s listed as Volume 3 then type:

 

Select volume 3 and hit enter.

 

Next, assign it a drive letter by typing:

 

assign letter=b: then hit enter.

 

Then type exit and hit enter.

 

Then enter the following commands, hitting enter after each entry.

 

cd /d b:\EFI\Microsoft\Boot\

 

ren BCD BCD.bak

 

bootrec /RebuildBCD

 

Hopefully at this point, you will see a message indicating 1 installation has been found and will get a prompt to add this entry - if you do, type Y and hit enter.

 

When complete, try rebooting the notebook.

 

Regards,

 

DP-K

Hi,


Boot configuration data is corrupted. This is the reason for boot issue you're facing.

Please do a repair install of Windows 10:
