I have a desktop computer with an Asus P8Z68-V LE motherboard. It has a Wester Digital 1 TB hard drive, Samsung SSD, DVD/CD drive, an external hard drive that is always connected to a USB 3 port and sometimes additional USB flash drives.
Sometimes when it is starting it hangs on the BIOS screen (the one that has "Press F1 to enter options"). When I do press F1 I can enter options. I noticed there's a boot option I don't recognize: "WD virtual CD 0748 1025".
Any tips on trouble shooting why the computer sometimes hangs when booting? The SSD is primary and the HDD is secondary. I only have windows 8 installed (though I use several VMs).
