Just built a new computer, Here are the components:
ASUS X570-Pro Motherboard, AMD Rizon 7 3700X processor, RAM 64 GB DDR4-3200 Ripjaws ,Graphics GIGabyte GeForce RTX 2060Super (8GB), Drives IntelSSD 6 M2 2TB (X2), Western Digital 4TB Black 7200rpm, TeamGroup 480GB SSD, Power Seasonic Focus Gold 850FX, Case Corsair Obsedian 500, Window 10 Pro 64bit DVD
My problem is I only have an external ASUS DVD drive and the ASUS Bios recognizes all the various drives but I can't see any way to install the Windows operating system onto one of the drives...ideally one of the M2 SSD drives. All my previous builds were Intel and before SSD drives. Any suggestions?? Thanks!
