    How old is your boot device? This error message is frequently associated with bad connection or a faulty drive.

    Try reseating your boot device to ensure good contacts with the connectors.

    Also, try get into BIOS and hit F9 to load optimized defaults, and then save and exit (F10).

    Your A115-31-C23T doesn't have HDD /2.5" SATA3 SSD/ M.2 NVMe SSD as boot device like most other laptops but using  eMMC soldered to motherboard. This can be a problem, hard to replace by the user.

    Sometimes, updating the BIOS can solve this "No Bootable Device" issue.

    Hope that your laptop is still under warranty and Acer can repair it. Or bring it to a repair shop with good reputation will be a good option.

    I am fear this low price laptop will have to be replaced, as repair cost probably will be close to purchase cost if not under Acer warranty.
  • I would try to disassemble the laptop and see if there is a possibility to install an ssd or an hdd:

    To the best of my knowledge, A115-31-C23T has eMMC for storage. Maybe some A115-31 models have the NVMe or SATA3 SSD/HDD connector. If so, @D3R3K is in luck.

    @D3R3K, can you take some pictures inside after opening the back of the laptop 
    and attached them here ? We can tell for sure with the pictures.

    Hi D3R3K you can check the status of the laptop storage by entering the BIOS. The information page will display eMMC details. In the field "EMMC MODEL NAME" there should be a 9 character reference. In the field "EMMC SERIAL No" there should be a number reference. If these fields are blank it suggests that the eMMC chip secured to the main board has failed of more than likely soldered joints have failed. The eMMC chip is secured to the board using a BGA [ball grid array] system. Your BGA will comprise around 96 individual contact points each originally secured with small solder balls. Unfortunately repair is a specialised technique perhaps beginning with an attempt to reflow the existing using a hot air system. If this is not successful then the chip will have to be unsoldered and either re-balled of replaced for re-fixing. Good luck with this let us know how you get on.

    Here's the inside of the computer

    The picture you provide isn't bright enough at the lower right hand corner, but I think I see a M.2 slot as the first picture provided by @egydiocoelho. I see another short M.2 Wi-Fi/BT card already in use, so it makes sense the open slot at the lower right hand side of the picture is a M.2 SSD slot. So far, I  do not know your laptop's hardware configuration. I want to know what CPU is installed to the laptop. 

    Can you take a close up picture of the M.2 slot, pay attention to have the female pins included in the view?  I want to find out how many notches are present in the slot. If there is only one notch, how many pins are there at the narrower side. This is important.

    How about reseat all connector wires/cables and make sure they are firmly in place while we try to determine what kind of drive you can use at the M.2 slot. If after reseating the connectors and your laptop can boot up, that will be the best. Otherwise, you may need to buy a new 2.5" SATA3 SSD or a M.2 SATA SSD (or M.2 NVMe SSD, to be determined) as a boot drive.

    Have you tried the procedures suggested by @Pinehunter ? Try it.
  • Looking at the image, the slots are not soldered:

    @egydiocoelho

    From the picture you just provided (is it the same as the one @D3R3K provided, or it is from the same model picture?), clearly the M.2 slot is not available. Looks like the connector for a 2.5" SATA3 SSD is not available too.

    @D3R3K may need to end up replacing the laptop since both 2.5" SATA3 and M.2 NVMe SSD are not available and the eMMC storage failed .
  • It's the same model. However, the user model comes with an emmc and does not come with the soldered m2 and sata 3 slots.
