No bootable device found

Question

Hi,

I have seen a couple of threads on this but still haven't been able to fix my problem. Comp is Inspiron 5570, Windows 10.

I get the "no bootable devices found" screen.

I've run diagnostics and it says all passed.

If I go into set up (F2)

Boot sequence: there is only the option of UEFI, Legacy is greyed out. If I try to add boot option it tells me file system not found. There is only Windows Boot Manager listed.
System information: primary HDD shows none
UEFI boot path security: always, except internal HDD
Secure boot: enabled

Help?

I am going to start computer with factory drive installed. SSD plugged in externally. Use Macrium Reflect to clone factory drive onto SSD. Then install SSD.

Sorry tech noob so none of that made any sense.

I tried putting a SSD to replace the harddrive and got the same thing.

Try putting your drive in, Insert a Operating System Install CD or USB. Start computer.

It will fix the bios settings to detect it and set it up....joys of UEFI....no Legacy option in Bios.

If you installed a different drive it wont be detected. You must insert an Operating system install CD or USB. It will install operating system and tell Bios you have a hard drive.

Press F2 when starting when you see the Dell logo.

Look at “First HDD”, can you see your harddrive listed?

Go to Advanced, make sure SATA Operation is set to AHCI

Make sure Bios recovery options all enabled.

Go to “Boot”.

Boot option 1 should be onboard NIC

Boot option 2 should be onboard NIC

Boot option 3 should be Windows Boot Manager

If all Correct, here you go:

Thanks.

I haven't installed another drive.

I don't actually have an operating system CD or USB. Windows 10 was pre-installed.

Would I be getting using a USB with the file from below?

Sorry, I did not state... Pressing F2 at start up takes you to Bios....those are the settings to look at first as listed above.

ML91 · Answer

OK I have changed to AHCI (was on RAID on before)But in terms of boot options I only have below&#xa0;Is this what you are referring to for first HDD?&#xa0;&#xa0;&#xa0;

Are you under warranty? If so...dont touch nothing.

help123a · Answer

Go look at the Dell site for your laptop with drivers. They just released a new Bios a few days ago and new firmware for your harddrive within the last month or so. Could be a known problem.

ML91 · Answer

Yeah purchased in Jan. I'm guessing my additional bad news of having no packed up my computer since would be I lose everything on it …

help123a · Answer

No...maybe you can remove the drive. Plug into another computer to get your files. Put back in your computer....and Warranty it.

ML91 · Answer

Thanks for your help.

Yeah, called a Dell. They'll send an engineer to replace the hard driver and I'll need to update the OS.

I have a week with the old hard drive before I need to send back. So I'll probably send it to a recovery business

Press F12 for boot menu to boot Ubuntu off of that thumbdrive.

help123a · Answer

To save you money.

With another computer download and install Ubuntu Live onto a thumbdrive.

Stick in computer and boot.

It will load an operating system and you can continue to use your laptop.

Use this operating system, browse drive...burn your files to a CD/dvd.

Do NOT click on Install Ubuntu....just use it in the “Live” state running from thumbdrive.
