My HP laptop does not recognize some bootable usb devices in the boot menu.

I have a HP tower and the laptop in my office and the tower will recognize and boot the a USB device that the laptop will not recognize in the boot menu.

 

Laptop: HP Pavilion dm1z-4100, BIOS HP vF.19 2/4/2013, Windows 7 Pro 64bit

Tower: HP HPE-480t, BIOS American Megatrends v6.10 9/16/2010, Windows 7 Pro 64bit

Example of non recognized device in laptop (OK in tower): USB HDD WD60 OUE-22 HCTO

The external HDD reacts the same as some memory sticks. All the boot devices appear to be syslinux bootable

I have never found a non recognized bootable device in the tower PC boot menu, but several in the laptop PC.

No problem with laptop using external CD/DVD drive

 

The problem appears to be in the BIOS, because the boot menu occurs prior to the operating system.

Latest BIOS listed in the updates is F.19 (same as installed)

 

Any comments?

Hi lrclost,

 

Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion dm1z-4100 Notebook and not recognize some bootable usb devices in the boot menu. Here is a link to secure boot.

This document will explain the differences in boots.

 

Hope this is helpful.

 

Thanks.

As stated in the original note, the installed BIOS for this laptop is HP F.19, which is the only choice provided by HP web site when entering both Windows 7 and 8 for the operating system (actual is windows 7).

 

The referenced article for secure boot BIOS does not lead to another version.
