Windows 10: No boot from USB

W10 boots normally, but the ability to boot from USB has quit, returning "Not Found" failures in the UEFI.
I noticed this yesterday, soon after installing Intel graphics update, and removal of 2 Linux GRUB entries ( debian and ubuntu folders) from the EFI.
Will a "Sys restore" point reverse this?



W10 Home version: 1909 18363.778

USB boot for bios update

Did the first step. It already doesn't work. Note the capacities and drive letters M:/N: The HP utility is about to format my raid-1 volume containing my 2 750gb drives. It thinks it's the usb stick. I can not select any other drives in the HP utility. My 512mb usb stick is U:.

Any other suggestions?

 

Help with USB Boot Image

I am trying to boot from my USB flash drive. I followed the instructions step for step that are in the article on this website. I downloaded the HP program and the USB Image zip file. I ran the HP flash program and pointed it to the folder where I unzipped the USB Image files to. I then copied all the files over to the USB memory stick as instructed. When I restart my computer and press F12 to go to the boot menu I have 3 options: SATA hard drive, CD-ROM drive, or USB Device. So I choose USB device and when it reads the USB memory stick all I get is the error "Non-system disk, replace and hit any key" Its like the USB memory is missing some system files or it doesnt have the master boot record or something. Somebody please HELP!!! I want to flash the bios in a new video card and I have to boot to DOS and I dont have a floppy drive and I have Win XP so a USB boot is probably the best option I have.
