This page illustrates the detailed process of recovering data from a failed Mac computer before you reinstall the macOS. If you are having the same issue, follow through this page to see how to get data out of the failed Mac computer before macOS reinstallation:
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
If you're encountering the same issue as said at the beginning of the article, your computer gets corrupted, and you have to consider a complete restart in Recovery Mode. At this time, you need to use the Disk Utility in macOS Recovery to erase your Mac hard drive first and go on to reinstall the macOS.
As we all know, erasing the hard disk on a Mac will inevitably cause data loss and make the files unrecoverable. You can use EaseUS Data Recovery Wizard for Mac Pro to back up data first and then recover data from the backup.
Back Up Your Mac and Never Lose Data
Back up and restore your MacBook/iMac without Time Machine, iCloud, or external hard drives.
This software enables you to create a bootable USB drive on another Mac that works well, then restart your Mac from it, and go ahead to recover files. Especially to restore data on the system drive under macOS 10.13, it's very safe to recover from bootable media. Useful for any emergency, no secondary data damage!
Now, follow the step-by-step guides below to see how to recover data from Mac that fail to start and needs to erase and reinstalled OS. The tutorial will be divided into two parts: how to create a USB bootable media and recover data from bootable media.
How to Create a USB Bootable Media

Step 2. The program starts to create a 2GB space and save the boot files. The rest space on the USB can still be used for storage.
Step 3. Once it completes, please follow the guide to boot the corrupted Mac from the bootable disc and start the recovery. We suggest you restore the data to an external hard drive.
