    But enabling it also didn't work. I even tried default settings but not working.

    >>>At first it was endless os 3 and then I tried Installing Ubuntu 18 and it's failed saying media file is corrupted. >>>

    Did you change anything in the BIOS before you tried installing Ubuntu? And was the Ubuntu installation stick GPT-partitioned FAT32 formatted? Jack E/NJ

    The USB pendrive that you used must've either been MBR-partitioned FAT32-formatted ---- or ---- GPT-partitioned FAT32-formatted. If you don't know which, then it was probably MBR-partitioned. A UEFI bootstrapper won't boot from an MBR-partitioned FAT32-formatted pendrive.  Jack E/NJ

    Please, then why did you say earlier >>>my pendrive was not GPT partitioned it was just FAT32 Formated>>> ????? I am not sure how your pendrive was prepared. Please explain how it was prepared. Jack E/NJ

    I prepared it with Rufus app at first I have downloaded Ubuntu 18.4 and then followed below mentioned instructions

    If the corrupted file is on the installation pendrive, you must re-make the pendrive installation with Rufus. Perhaps your Linux iso didn't download properly or Rufus didn't properly incorporate it to the pendrive.

    If a re-make still fails with the media file corruption, you should either use another pendrive or perhaps another Ubuntu-based installation like LinuxMint 18.3 Cinnnamon. But it must be GPT-partitioned FAT32-formatted for your machine's UEFI bootstrapper. Jack E/NJ

    Please only one change at a time! Why did you re-format the HDD now!!! Did you do this from another machine's USB port? Is it still GPT-partitioned? What file system format? Jack E/NJ

    What operating system uses the NEFT file system? This is neither for Windows nor Linux. Jack E/NJ

    Only the USB Linux installation pendrive uses FAT32, not the HDD you're trying to install Linux on!!! Jack E/NJ
