HP ENVY TE01 3XXX BIOS won't recognize LG EXTERNAL USB dvd rom drive.

[james2993]

No error message, when I try to bootup to a bootable disk, the hp envy bios doesn't recognize my USB External dvd rom, even though in the bios boot order,  I moved (USB CD-DVD ROM to the top position underneath UEFI BOOT ORDER. and moved my internal dvd rom *which I don't have* to the bottom of the order.

  I even booted without SECURE BOOT and the bios still didn't recognize my external drive.  IT merely says.

UEFI BOOT SOURCES

OS BOOT MANAGER

WINDOWS BOOT MANAGER (WDC - 1st hard drive

WINDOWS BOOT MANAGER *WDC   2nd hard drive

that's it. 

I also updated to the latest Bios firmware two hours ago and rebooted.

Can anyone help me?  I still have five days to return this if it can't be fixed.  Thanks in advance.

You need to use the USB3.2 ports on the front, not the USB2.  Even then, you may need to have a powered USB3 hub to properly power the optical device.

I have several of the "laptop" type DVD & BlueRay.  They use 1.5 to 1.8 amps.  That comes to 7.5 and 9 watts respectively
Your system has a 310 watt power supply.  That is actually pretty good.  I assume you do not have any other devices on the USB3 ports and the full 7.5 watts is available.

If your external drive is powered verify it can spin up when just powered on and not plugged into the USB port.

It is also possible that the media is not recognized as bootable by windows.  I have had problems booting ubuntu from CD and windows ISO takes a double layer.  My experience is that 3rd party apps do a better job of creating a bootable drive than using Windows "free" built in burner.

Beemerbiker.

I'd like to apologize for being so late.  I saw your message early, but my password didn't work so I couldn't get in to reply to your message and thank you until now. 

In regard to your  reply, The HP user Manual for the TE01 doesn't refer which slot is the 3.2 slot so maybe you could show me a photo or tell me which usb slot on the  front, starting at the top & going down, where it is located.  my hp users guide only says one slot is for charging phones, another slot is for copying, etc. It doesn't list the USB port versions by number.  Also my LG External dvd writer doesn't have a power supply so that might be why the bios doesn't recognize the drive.  I never had any of these issues with my earlier HP Desktop towers because I could add an internal DVD player or it had Legacy support.  In fact, my first HP, having a small 20 mb hard disk, at least had a floppy drive that I could boot up from to install Windows 3.1 or windows 95.  Why HP got rid of the bay that would allow that makes no sense.

But still, my biggest problem with this is that there is no ENABLE LEGACY SUPPORT that would allow my USB Bootable flash drive to boot up.  UEFI & GPT drives are not that old yet.  Many of us continue to use those boot options.  I use Paragon backup and restore (which has never let me down), but I haven't been able to access it on my external drive with this particular machine.  There is nothing in the UEFI bios to boot to legacy drives.  I had USB enabled and Secure Windows Boot was disabled to see if that worked.  Then I moved the USB & EXTERNAL DVD DRIVE to the top of the BOOT Order, but when I hit F9 at bootup, HP BIOS only allowed me to boot from two internal hard disks and EFI kit, which led to nowhere.

Is there any reason that HP would get rid of legacy boot?  This doesn't seem to be a windows issue since it is the bios that will recognize a usb bootable flashdrive or not.  I'd appreciate your help (or anyone's Help) if I am doing anything wrong.  Please offer your advice before I return this to Best Buy.  I need to boot up that way in case I want to use Minitool Hard drive partition which I paid for or any other software on boot.  There are a million reasons to boot up outside the Windows 11 OS.

Hopefully it may be something that I had misside.  because all of my computers have been HP since they usually last 4-5 years apiece.  But still without an internal dvd drive or the means to recognize it in the bios bootup, I probably can't use this

thank you, james.

The manuals available do not show any pictures but a description is provided on page 6 & 7 of the user manual

use the superspeed ports.  However I was unable to find any power specs for the usb ports of your system

I probably have same LG dvd you have.  It is usb 3.1, not USBC and does not have a power adapter.  Mine is rated at 5v 1.8 amps which requires 9 watts. 

From wiki table "USB power standards" it seems 7.5 watts is available for USB 3.1 

USBC (USB 3.2) can provide 15 watts.

Possible you may need a USB powered hub.  Can you put your booting software on a USB flash drive?
