HP won't boot via USB

[Dolby]

The other day I knocked the plug out my HP Microserver/SSD HDD and when I turned it back on, it said 'BOOTMNG not found'. After Googling, I see a probably corrupted something and need to reinstall Windows 10 via USB boot.

I made the USB on my other PC, popped it into the HP, went to BIOS to select boot priority to USB and ... nothing. The only 2 options are the HDD and the Network.

Am I missing something to allow it to boot up?

Sometimes older BIOSes list USB drives under hard drives. Check the hard drive boot order to see if its there.

+1 Win 10 media is formatted as USB hard drive.

You probibly have UEFI secure boot active.

Use rufus to make a boot USB (Selecting GPT partition for UEFI option) Oh and most UEFI reads the USB as HDD.

Does your stick have a EFI\boot\bootx64.efi? It needs to be fat32 too. You may need to disable secure boot but probably not for win10

Thanks for the help ; sorted one issue out (does indeed read it as HDD) - but the other issue is that it isn't in the selection of boot priority

EDIT : Looking closer, I may not need to reintall! It's just booting off the wrong drive, hence BOOTMGR missing! It should boot off 4th drive

What happens when you change it to Network there? Have you seen an option for secureboot?

I just realised I can change the order of the HDD. lol

So boot priority only selects HDD #1 and I mapped HDD #1 to the right drive ... seems to work. Sorry guys :/

This whole thing started because I kicked the plug out by mistake - odd how that effected bios!
