macOS Reinstallation Deletes Everything. What Can I Do
"My macOS Catalina got corrupted, and the login screen doesn't appear. If I reinstall macOS from the recovery menu, will my previously installed software and data be deleted? And if so, how can I back them up on a hard drive? The data and the software are very important to me."
Reinstalling macOS of macOS Recovery can help you replace the current problematic OS with a clean version quickly and easily. Technically speaking, simply reinstalling macOS won't erase your disk or delete files. You probably don't need to erase unless you're selling or giving away your Mac or having an issue that requires you to wipe. Besides, If you suspect there's something wrong with your startup drive, you can use the Disk Utility to scan and repair them from the recovery screen, which might be a quicker and more convenient alternative than erasing and reinstalling your macOS.
How to Recover Data When Mac Needs to Be Erased and Reinstall macOS
