Troubleshoot my daughter's Laptop which is an MSI GP70 2PE Leopard , installed with Windows 10 Operating System

 


Troubleshoot my daughter's  Laptop which is an  MSI GP70 2PE  Leopard ,  installed with  Windows 10  Operating  System .  Booting up the Laptop  causes an  error  that says  below:

GRUB LOADING STAGE  1.5                                                                                              GRUB  LOADING ,  PLEASE WAIT                                                                                      ERROR  21

It all started when I decide to install  Linux Operating System  KNOPPIX  8.6  on  a  500 GB  SATA  Hard Disk Drive  with the help of a  SATA/IDE  adapter as shown below ,  which is then connected to the  MSI GP70 2PE   Laptop .

One end of the red-colored  SATA cable is connected  to  the  500 GB  SATA Hard Disk Drive and the other end of the red-colored  SATA cable is connected to the  SATA/IDE  Adapter .  The  USB cable of the   SATA/IDE  Adapter is then connected to the  USB port of the   MSI GP70 2PE  Laptop .  To  power the  500 GB SATA Hard Disk Drive ,  I use an External Power Supply .





I managed to successfully installed  the  Linux Operating System  KNOPPIX  8.6  on the   500 GB  SATA Hard Disk Drive  side-by-side  with the  Windows 10 Operating System (which was preinstalled on the  MSI GP70 2PE  Leopard)  with the  help of  GRUB BOOTLOADER . Having said that ,  I can can toogle  between  the  two  Operating Systems , that is ,  Linux  OS  KNOPPIX 8.6  and   Windows 10  OS , on the  MSI GP70 2PE  Laptop  with  the help of  GRUB BOOTLOADER .

The problem happen after I decided to remove the  500 GB  SATA  Hard Disk Drive from the   MSI GP70 2PE  Laptop  and  decided  to boot up the Laptop without  the  500 GB  SATA Hard Disk Drive . 

After booting up the  MSI GP70  2PE  laptop , I got the error as shown below :

GRUB LOADING STAGE  1.5                                                                                                GRUB  LOADING ,  PLEASE WAIT                                                                                      ERROR  21


Following the instructions given by this site , I managed to solve the problem .


 The excerpt of  the instructions , the step-by-step procedures are shown below :




 The  "bootrec"  Utility really work for me , and after I restart the  MSI GP70 2PE  Laptop , I managed to get the  Windows 10  Operating System up and running without any errors .
