I have had a custom built PC with an ASRock mobo running for the past 6 years. I had Windows 7 updated to Windows 10 when Microsoft spammed the upgrade. A couple months ago an update went wrong and I'm greeted with a blinking cursor on a black screen on startup. Specs: Mobo: ASRock Z87E-ITX UEFI P2.50 CPU: Intel Core i5-4670K RAM: 8gb ram I've disconnected my graphics card. I'm trying to boot from USB or CD-rom, but am unable to select or specify these devices in the boot order menu. These device are not listed, only connected SSDs. I've tried several different Linux live/Windows bootable USB images on 8-16 gb USB 2.0 and USB 3.0 sticks. I've prepared the images as MBR and also tried GPT. When inserted into the mobo's onboard USB 2.0/3.0 ports, I cannot find an option to boot from USB in the bios/UEFI. I'm using a wireless keyboard with USB dongle to navigate the Bios screen, so I know that USB is enabled. I can find the boot menu, but the only option available is the hard drive boot order (my 2 installed SSD drives are selectable). I cannot select a UEFI: USB storage or find my CD-ROM drive when its plugged in. I've used an external DVD drive with the original Microsoft 7 installation CD-Rom and have not luck either. Is there a setting that is keeping my Mobo from seeing these devices? |

Thank you for the response. Prior to disabling CSM, here are my boot options. I only have hard drive boot options.  After disabling CSM, I receive no boot options.  For reference, I have a USB 2 jump drive with a linux live image, a USB 3 jump drive with a linux live image, and an external CD/DVD drive with official Microsoft Windows 7 installation CD plugged in to the back of the motherboard.

With CSM enabled, I hit F11 at boot and receive the following options. Only my SSD drives are selectable.
