When I do the Command + Option+Command +R I get the Recovery screen and I try to reinstall Mac OS but It doesn't show a disk, to install to. When I do the Command + R+Power for recovery mode I get a spinning globe and a clock. Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume).

Please note that this will reformat the destination partition. Try using Disk Utility/Restore to copy the data to a new location. When it is done, close the application by clicking Disk Utility and then Quit Disk. Click the Erase button on top ribbon of Disk Utility to start erasing your hard drive for factory reset MacBook Pro. Select your main hard drive usually called Macintosh HD. When the Recovery Mode Utilities window shows up, pick Disk Utility and click Continue. The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. Select your disk in Disk Utility Choose View Show All Devices (if available) from the menu bar or toolbar in Disk Utility.

From the utilities window in macOS Recovery, select Disk Utility and click Continue.
