No bootable devices found (XPS 15 9550)

Hi,

After installing Windows Creators edition and also some last Dell updates I am not able to enter my laptop anymore. I receive the message "no bootable devices found".

I have an XPS 15 9550

System BIOS: 1.2.25

I tried via F2 to check if secure boot option is enabled : Yes

I did Diagnostics Test and no issues found

How to fix this problem?

Thanks and regards,

Rene

Hey Rene,

I had exactly the same problem yesterday after bios update of Dell.

Unfortunately i am in Moscow, for my studies and it would be really difficult for support;

so hopefully i found a solution, which run for me, i think the bootfile is corrupted, and you should try this :

Good luck.

Thank you Hk417a, you are awesome!

I got trapped with 1.2.25 too, "no bootable devices found" right after successful completion of BIOS update.

These kind of things make me never wanna update it again.

Unplug the dock, if you're using one, and use a regular AC adapter instead. 1.2.29 makes dock USB go berserk again.

So if I understand this correctly, affected users found their systems set to Legacy rather than UEFI? If so, fyi just setting it back to UEFI should have resolved the issue without the need to manually add a boot entry since the UEFI spec mandates that systems check any detected devices for a bootx64.efi file at that \EFI\Boot path automatically.

But either way, Dell BIOS updates in addition to making USB devices attached via the TB16/WD15 docks practically unusable are now also modifying boot settings and rendering disks unbootable without making these changes to restore functionality?
