Windows 10: How to use Grub command line to setup \Boot\BCD

I keep getting windows failed to boot after chainloading my flash drive containing my windows 10 installation media on my Asus X705U after using it to previously restored the computer

:)

 

GPU-Z what command line parameter ?

Suggestion: /? (-?) and /help (-help) command-line arguments to show a list of all possible arguments in a small window. *Smile

 

GPU-Z what command line parameter ?

Current /? (-?) or / help (-help) parameter is invalid

 

If I roll back my Win10 to Win7, will I be able to upgrade again when you've sorted out the major problems?

Hi,

I suggest you to follow the below steps and check if it helps.

Go to the command prompt through Windows Recovery Environment and re-build the BCD and check if it works.

Follow these steps to do so:

• 
  Boot the computer using the Windows bootable DVD.
  
• 
  On the ‘Windows Setup’ wizard click on ‘Next’ and click on ‘Repair your computer’.
  
• 
  You will then see a blue screen and an option to choose.
  
• 
  Click on ‘Troubleshoot’ then click on ‘Advanced Option’ and then click on ‘Command Prompt’.
  
• 
  Type these commands on the Command Prompt:
  
  bcdedit /export C:\BCD_Backup
  
  c:
  
  cd boot
  
  attrib bcd –s –h –r
  
  ren c:\boot\bcd bcd.old
  
  bootrec /RebuildBcd
  
  (Press Enter after each line of command)
  
  Following these steps will re-build the BCD.
  

Thanks.
