     Hello Viseuth:

     Thank you to help us voluntarily.

     I follow you and the article, tried to press the "ESC" earier and then appear the options. 

I select "F9" but still failed. 

    The previous bootable-CD disk doesn't boot the screen into "DOS" which I desired.at  is the way

    For 15-ay039wm, what's the way to boot the system into "DOS"? [I am used to go to "DOS" to do somethings

such as BACKUP with the GHOST.]

You're welcome.

Did you enable legacy, disable secure boot before booting from CD?

     Hello Visruth:  too bad!

     I follow the instruction to disable the secure boot and enable the legacy or CD/DVD boot several times,

it doesn't work!   

      Make the thing even more bad, the noteboot does boot/open again?   It is now a dead pc!

       Wish God to come!

Hi:


There is no reason that instructions to change BIOS to legacy, disable secure boot to boot from discs would make your laptop dead.

I'm not sure why you tried it SO MANY TIMES. It should work in the first try itself.

May be there is some other bigger issue with your notebook. That may be the reason your laptop died.

May be the battery discharged quickly, or AC adapter power didn't charge your notebook, ultimately pushed notebook to die.

Anyway, do a hard reset, follow the steps here:

    Hello Visruth:

    After around one hour, the pc waked again. You give me a good suggestion: hard reset. It must be a

important repair method, I must do it later.

   For changing the booting, the article, you gave me, only say to disable secure boot. I re-follow your suggestion, also enable legal boot! now the F9-->boot add a option: "CD/DVD Boot"  

   This option is what I want although it still not booting into "DOS"   I guess the reason, perhaps, there is no FAT partition

in the whole hard-disk.

   Please tell me the way to change a partition with NTFS into FAT/FAT32!

   Thank you.

They is good to hear.

No need for changing hard drive file format to go to command prompt.

Follow the tutorial I posted in my second post in this thread.
