Recover Data When Your Computer Was Unable to Start First

You need two things for help, including our third-party EaseUS bootable data recovery software and another working computer. EaseUS bootable data recovery software recovers lost data even when the operating system fails to start or crashes. It is mainly designed for data recovery cases of any system crash or starting problems. Follow the steps to rescue files when your computer cannot boot into Windows:

Step 1. Create a bootable disk

Launch EaseUS Data Recovery Wizard, choose "Crashed PC" and click "Go to Recover".

Select an empty USB to create the bootable drive and click "Create".

⚠️Warning: When you create a bootable disk, EaseUS Data Recovery Wizard will erase all data saved in the USB drive. Back up important data beforehand. 

Step 2. Boot your computer from the bootable USB

Connect the bootable disk to the PC that won't boot and change your computer boot sequence in BIOS. For most users, it works well when they restart their computer and press F2 simultaneously to enter BIOS.

Set to boot the PC from "Removable Devices" (bootable USB disk) beyond Hard Drive. Press "F10" to save and exit.

After you have exported data to a safe location, you can now fix the unbootable PC or laptop. Usually, when this happens for the first time, just wait for the Startup Repair utility checking the problem for you. If the checking process goes smoothly, largely, it's because the computer shuts down improperly. But if you have waited for a long time, you can follow the solutions below.
