Trying to upgrade the CPU's of a HP Proliant ML350P G8 from E5-2690's to E5-2637 V2's. The hp website says to update bios with hp-ivb_update-1.80-2. And to do that i have to turn it into an iso file (which i did using rufus, in FAT32) and boot from the USB drive with the iso on it. The directions and file are found here (special firmware update needed). The next direction (After starting the upgrade program, the program will......). I can't get this far because all i get when i boot off the usb is (BOOT: ). I don't know how to start the upgrade program. It doesn't outrun. I'm stuck, and I'm guessing its related to my lack of experience. Thanks in advance to anyone who can help.
