Booting to BIOS

look to see if it has some sort of "boot to bios" option. im lost with this one....i cant think of much more than what ive suggested. Most Motherboards have different Bios/booting options. Try them all , see if makes a change.

if nothing works, time to contact the Manufacturer.

Sorry I couldnt be of help

 

Win 10 boots...

I can't answer to the speed of Win-8 booting. I tried the Win-8 preview and went back to Win-7 after a month. They say that Win-8.1 is a lot better than Win-8 was.
My Win-10 TP is working well ATM.

 

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.
