Windows 10: Cannot boot into Bios, cannot boot from USB, or to recovery

I'll try to be as clear as possible even though English is not my mother tongue. I installed last night windows 10 64bit to my HP Pavilion 15-b109so, which originally came with Windows 8 preinstalled. I wanted to do a fresh install of Windows and also to install Prime OS, so I wanted to have 2 OS at the same time with dual boot, as I've done it before on another laptop, which had Win 8.1 installed to it.

Booting from USB on x38 Motherboard, NOT?

See sys specs... ASUS ROG x38 motherboard, flashed to x48 Rampage.

In BIOS under "Boot Device Priority", I select and of the 3 boot device slots, and no where do I find an option for USB, these are the only options in each:

• 1st floopy drive
• HDD: P0-WDC WD2500KS
• ATAPI CD-ROM
• Disabled

Is there a place in the BIOS to enable boot from USB?

It's AMI, says v02.61 on the BIOS screen

 

How to boot from a W10 recovery usb drive(non UEFI bios)

I recently installed W10 with the NOV upgrade, works fine. I prepared a recovery usb drive and it has the required content. My system's bios just lists the following boot order: floppy disc, CD drive, sata hard drive, dvd drive, but no choice for usb drive.
I tried switching around the order but no luck. motherboard:asus P5B deluxe. Another system with UEFI bios works fine and boots from the usb drive. Is it possible to boot from my system from a usb drive, and if it can be done how shoul I do it.

Thanks

 

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.
