Chrome OS is missing or is damaged / No bootable kernel found on disk C740 Series

My cousin had a Chromebook that he didn’t use, and he saw that I needed one so he gave it to me. I used it and it was amazing. But then one day, I was watching YouTube and saw that my battery was low, so I plugged it in. A while later I saw that it was at 100% so I unplugged it and as soon as i unplug it, it goes to the “Chrome OS is missing or is damaged. Please insert a recovery USB stick or SD card.” I’ve done holding esc and f3 then clicking CTRL + D and that gets me to the os verification off thing. Then when it is supposed to go into a recovery mode, it beeps at me twice and then takes me back to the error screen. Please help me fix this because my school starts soon and I need a working chromebook now. I have the C740 Series.

    Hi ,
    If the above steps do not resolve the problem, you can create a recovery drive from a Windows, Mac, or Linux computer, and use it to restore your chromebook ;

    To reinstall Chrome OS using a USB flash drive, you must have a PC with internet access and a 4GB or larger USB flash drive. To create your USB flash drive, visit our Create a USB Recovery Flash Drive for your Chromebook article.

    Use the following steps to reinstall your Chrome OS with a USB Recovery Flash Drive.

    1. Press and hold the Esc key and refresh (F3) key and then press the power button to turn on the Chromebook.
    2. The Chromebook will boot to Developer Mode. Insert your Chromebook USB recovery flash drive.
    3. The integrity of the recovery media is verified, then the system is recovered from the USB flash drive. This process takes about 10 minutes to complete.
    4. Once the system recovery is complete, unplug the USB flash drive.
    5. The Chromebook will restart automatically.
    6. Follow the on-screen instructions on the Welcome! screen.

    Your Chromebook is now back to factory default settings.
