HP Pro Desk 400 G1 MT boot issue
New machine boots fine as long as no USB HD's are connected, easy fix right? Well no..
So I went into the bios via F10 and eventually disabled the UEFI and made the HD the first boot under legacy.
Still no joy! Went back into bios and everything was still as I changed it.
Re-booted machine and instead of f10, used esc to bring up the boot menu. The boot menu indicated that everything was again on, in other words, the UEFI was not grayed out and the boot order was was as default setup would display.
Any thoughts? Does this regardless of front or rear USB ports used.

it can also be a bios that causes it, so try updating the bios
also - the connected usb - is that usb 3 ?

Does it refuse to boot with an error message or does it simply sit there with a black screen if any USB drive is connected?
I've seen some mainboards doing this when USB disks were connected. One of themwould boot eventually if the USB disk wasn't too big, but if it was big, it wouldn't boot. There was nothing I could do to fix this, except to have the USB disks removed or turned off during the booting process.
Exactly the same thought rindi, that's why I am asking if it gives errors or not.

VB ITS Will try.
NOBUS one device is, there are 2. Have tried with each single and still happens.
UPALA Ok will look at.
RINDI The biggest of the 2 is a Seagate, 3 TERA and is USB 3.
NOXCHO Yes throws an error no boot device found.

Check if it boots with a USB stick. The stick should be non-bootable. Just data stick. If it behaves the same - sorry you can't do much here. Updating BIOS does not help as well. As long as you have the USB storage device connected it will fail to start.

Found a post on a Microsoft Forum that stated the only resolve was to install a 3rd party PCI USB board.
Will advise.

Hopefully I will put hands on this unit this week or early next week and be able to close it out.
Thanks
Thanks
i agree that was happening on some (older) motherboards
ASKER
Nobus, you agree with installing a 3rd party USB board? for a resolve?
i have had no occasion to test it; but it seems a good test - and it does not cost much

So inserting a new USB card resolved the boot issue, so now to decide who gets what??
that's up tyou to decide -one post, or several helpful ones

This was he ultimate resolve for me on this PC
If you configured Windows in UEFI mode then that may explain why you couldn't boot to Windows after disabling UEFI completely. I'd recommend you switch this back on.
Once you've done so, go back into the BIOS then go to Storage > Boot Order > UEFI Boot Sources > highlight your hard drive > hit the Enter key > use your up arrow key until you are at the top of the list > press Enter again to drop the hard drive at the top of the list
Save the changes when done then try rebooting with a USB drive plugged in, it should boot straight into Windows.
