So I just built a Ryzen 5 system last week and I'm having problems with it already. When I turned it on this morning, I expected it to boot normally to my Win10 installation in my SSD. However, it didn't boot and instead gave me the infamous 'No bootable media, press Ctrl-Alt-Del to restart'. These are my full system specs: CPU: AMD Ryzen 5 1600 @3.2 GHz(Stock, no OC) CPU cooler: Stock AMD Wraith cooler Motherboard: Asrock AB350 Pro4 RAM:16GB Corsair Vengeance 2x8 kit GPU: Aorus RX 570 4G (20 MHz base OC) SSD: Sandisk 240GB SSD HDD: Seagate 2TB PSU: Corsair CX550 Watt ATX Please keep in mind that my case(which I don't know the details for) doesn't have any SSD mounts, so I had to(most ghetto solution) tape the SSD into the 3.5-inch drive bay. If anything's my problem, it'll probably be this, but it might be something else. Please keep in mind I'll be on holiday from Sunday and should be back on Thursday, so I can still respond during that time, but won't be able to do any troubleshooting.And also I won't be able to purchase anything big, like a new part or something. My SSD is my main boot drive which has Windows 10 on it, and the 2TB drive which used to have a copy of Windows 7 on it, and when I go to BIOS, it finds the SSD and the 2TB HDD, but in the boot options it doesn't say I can have it as a boot device.
