I’m desperate I desperately need answers or help

I don’t know what to do anymore. My Mac Pro from 2010 which was running 10.14.5 had every bit of information and the os it’s self erased. The data has also been overwritten so there is no getting it back. My Mac Pro now boots in Recovery mode. It only gives me four options. Time machine backup. (Which I don’t have.) Install MacOS (which takes me to a screen to download Mojave but only gives me the option to quit.) Online assistant ( which is pointless.) and Disk utility. I have 1 250gb western digital hard drive with a bit of information that I don’t know what it is on it. I don’t want to erase it because I don’t know if I’ll be able to get back to the recovery screen. ( I also have a 1 TB crucial mx500 ssd which I connected sata to usb and tried to install macOS Mojave onto but now the ssd is goofy, it won’t let me partition it and the storage is all messed up with it.) I’m so stressed that I ruined my computer that I can’t even sleep at night and I just don’t know what to do... Can someone please help me out and maybe tell me a way that’ll guarantee an OS will be installed on my Mac? I also only have a gtx 680 graphics card and a sapphire pulse rx 580 graphics card.

Mac Pro, macOS 10.14

I will try, GPasker. You could boot( start up ) from a bootable installer usb stick/usb drive. You need another computer to do this. You would be doing a clean install,so you would be booting up from a dvd copy of snow LeoPard.Apple charges $30-39 for a copy, assuming you have a working dvd drive inside the Mac Pro or connected to it. Reboot and hold down the ‘c” key on the keyboard. If you had a recent OS installed, Lion (10.7 or greater) you would have a Recovery Partition built in. Reboot, wait for the chime and hold down the Apple and R keys on the key board together in startup. From there you can run Disk utility and disk first aid. And reinstall the OS. No vackup, huh? This is gonna be a bit tough... i”’d go for Startup Manager/aka boot manager, make the stick and once it done shutdown your mac, connect the usb stick and restart your mac. IMMediately hold down the Alt/option key on the keyboard until you see the startup manager. Pick a drive with left and right arrow keys ane press” Return/Enter” on your key to pick it. If your drive is toast, disk drill can help you with that. I’d also suggest changing your pram battery( behind the card on thevack plane. Br2032 recommended but Cr 2032 will do. Also do a reset smc/pmu and a deep nvramfix-hold down apple,ption,p and r keys held down on the Keyboard for 3 chimes then let them go. Try th alt/option “Option” right away after that

goood luck
