No Bootable Device Found

I have an Acer Aspire V3-371 Series laptop here and it can't boot as it cannot find any Bootable device. I originally tried to reinstall Windows, that didn't work. So I tested the original HDD. It was defect to some degree. So I changed it out for a new one and installed Windows again. The PC worked! But just for a week or so before the exact same problem occurred again... Now I'm out of ideas what it could be.

It sounds like there is a defect in your power supply that is damaging your hard drive. Can you test your other components and see where the problem is coming from. Have you tried posting your question on the official Acer support forums: https://www.acer.com/ac/en/US/

@lukecetion, what do you mean the original HDD was "defect to some degree"? Have you run a recovery disc like http://www.hirensbootcd.org/? Hirens has hard drive diagnostic tools, master boot record tools, antivirus software, etc.

Hi @lukecetion ,

Is the HDD being detected in BIOS, you never said?

による

@jayeff Yes, it is being detected.

Hi @lukecetion ,

If UEFI is enabled, what options are available in BIOS for the boot sequence?

Don't know your laptop or BIOS but can you add a boot option at all to the list of options?

Perhaps one that shows Win 10 HDD or Win 10 USB for example.

Just a thought.

Have you tried resseting the bios?

What version of windows are you using?

If you are using Windows 8/8.1/10 have you tried switching between legacy and UEFI?

Do you hear hard drive clicking sounds? if not just try burning a Windows ISO in a usb stick and reinstalling the actual OS

I've tried to switch between Legacy and UEFI. I also hear no clicking sound, and I've tried to reinstall the OS through a USB stick as well. I have also tried to reset every possible thing on the computer, that also includes the BiOS.

If No legacy option is showing in boot menu then what to do?

I took Techblogchain’s advice and changed from UEFI to Legacy. That just made things worse. Could it be that the SSD drive is broke? I can’t tell when all I see a a black screen with :

No bootable device — insert boot disk and press any key

In Legacy BIOS mode it will boot from neither SSD nor HDD. Back to UEFI then.

I had the same problem as you so I followed the instructions again and change back to UEFI but left the other and my computer came back on. I guess I’ll see how long it works.

@Mykrashna sateesh here is what I've found, solution to my problem, no bootable device found, well the SSD was burned. Even though I was able to hear the HDD's clicks.

I changed to Legacy and got the DOS message No Bootable Device - insert boot disc and press any key.

changed it back to UEFI and it worked again for a a few days then same problem. I kept going through the switching between the two to get it working again and that worked 3 or 4 times. I even reset windows to a previous work point (thinking the problem was caused when I removed ACER programs on the laptop). Anyway bad news is, the switching doesn’t seem to get it going now. I feel pretty silly that I didn’t create a bootable USB when i managed to get it working again

Did you transfer all the files including windows itself onto the other hard drive ? If yes the program you used is probably the issue.

Is the SATA cable properly inserted? If there are no clicking sounds coming from the HDD, that could be the problem. Otherwise, if you have an SSD , clicking noises are a horrible sign (I think) , and something is definitely wrong with it.

SSD’s can only last for about a year or two before corrupting. Try a HDD if you’ve had an SSD for a while.

Try downgrading your BIOS or UEFI if you recently updated. This could be another reason for the HDD or SSD failure.
