Subject: HP ProBook 455 G9 – BootDevice Not Found (3F0) Error

Dear HP Technical Support,

I am writing to report a serious issue with my HP ProBook 455 G9 laptop.

The laptop is currently unable to start Windows. When I power it on, it displays the following error message:

“BootDevice Not Found”
“Please install an operating system on your hard disk.”
“Hard Disk – (3F0)”

As a result, I am unable to access the operating system or use the laptop normally.

I would like HP Technical Support to investigate this issue and determine whether it is caused by a failure of the internal SSD/storage device, corrupted boot files, BIOS/UEFI configuration, or another hardware problem.

If the SSD or another component has failed, I request that HP assess the laptop for warranty repair or replacement, if applicable.

Please provide instructions for the next diagnostic steps and advise me on how I can arrange a repair or service appointment.

I would appreciate your prompt assistance, as the laptop is currently unusable.

Kind regards,

[SIMON NETO]
HP ProBook 455 G9
Serial Number: [5CD31827RT]
Product Number: [5Y400EA#ABF]
