I have an Acer Aspire S 13 (S5-371T-35PD). Laptop worked fine until sudden black screen, then "No Bootable Device" error after restarting. On BIOS: I've checked for correct time & date, tried F9 for default settings, and changed UEFI to Legacy. I also unplugged and plugged back in the SSD. I don't know how to fix this. Please help!!!

    Change all the bios settings back to how they were before, as changing the bios settings to MBR/Legacy will NOT fix this problem.

    A "No Bootable Device" error in 99% of cases is because of your laptops M.2 SSD PCIe3x4 is faulty and the laptop doesn't recognize that there is a boot drive! So check your PCIe3x4 M.2 SSD drive, as a 2018 laptop like the Aspire S5-371T could have a damaged boot drive, take the existing boot M.2 SSD drive out and replace it with a new PCIe3x4 or evne a Gen 4 M.2 SSD type drive and do a Clean Install of Win-10, as that should fix your boot problems and you will NOT GET the »» "No Bootable Device" problem. try that and let us know. Good luck.

    Hello, thanks for the response! Yep, I have already changed the bios settings back to default after none of the fix attempts worked.

    How do I check my PCIe3x4 M.2 SSD drive? Is there a way to check it is faulty?

    If the M.2 SSD doesn't boot then its faulty, if you have valuable data on this drive don't do anything with this drive as you could damage your data. Take the drive to a Data Recovery Technician so that he can recover your data, if you do persist, then buy an external M.2 SSD case with a USB-C cable and plug the drive and set the bios to USB boot and test this drive externally but if you do this its risky as you could lose your data if the drive doesn't register or the laptop goes into a loop, I take no responsibility for any damage to your data, as an external drive needs to be "Ejected" from the taskbar for their data to be 100% safe when you remove the USB plug out of the laptop port. Good luck.
