Rebooting in loop with media direct after shutdown

Hi,

I have E15o5 laptop. I accidentally pressed the media direct button when the system is OFF. When i ON the system, it is starting in media direct screen. System is rebooting with media direct when i shutdown the system.  Now i am removing the battery to close the system due to rebooting loop.

Note that, I didn't installed the media direct software on system.

I have shown to laptop service (local). They are not able to resolve the issue.

I have tried below methods to resolve the methods.

1) I have tried to reboot the system with media direct repair utility. And, went to MD2 folder and gave the REPAIRE command. It wasn't resolved the issue.

2) Used FDISK with option /MBR. It is also not fixed the issue.

3) Used FDISK to repartition the HDD. It is also not resolved the issue.

4) Used KILLDISK utility to make low-level-format. It is also not resolved the issue.

Also, i have searched the internet and didn't found the resolution to my problem.

PLEASE HELP ME TO START MY LATOP WITHOUT MEDIA DIRECT. It looks like i  need to buy another laptop if we pressed the media direct accidentally.
