Hi guys,

apologies for using English - my Russian is worse than your Greek

I have this HP-15 laptop that will not load OS from any media, HDD, USB etc.

I have flashed both the BIOS and IO controller firmware using Vertyanov's programmer. I have also enabled legacy boot and disabled secure boot in BIOS. The laptop starts, detects HDD or USB but says there is no операционная система. I tried with Windows and Linux.

Any ideas??

f-bone Hello, did you confirm changes in BIOS settings after the reboot? Like this:



Maybe there is an operating system choice in the BIOS (Win8 / 10 - Other OS)?

Have you tried the UEFI bootloader at HDD/USB?

hi primesvc,

I did not get that screen with the confirmation code. I was getting straight to the error message of no operating system.

BUT you gave me a great idea. I RE-ENABLED secure boot and then DISABLED it again. I was then asked for the code+ENTER.

this way it worked!

thank you primesvc.

You are welcome
