When Windows fails to boot, your files may still be stored on the internal hard drive. This guide explains how to recover data after OS crash by creating a bootable data recovery tool, start your crashed computer, and recover important files without loading Windows.
A crashed OS can prevent you from accessing documents, photos, videos, and other important data stored on your computer.
Can You Recover Data After an OS Crash
Yes, you can recover data after system crash if the storage device is still recognized and the lost files have not been overwritten by new data.
An operating system crash does not always mean that your files are permanently deleted. In many situations, your data is still stored on the internal hard drive or SSD, but Windows cannot load properly to access it.
When Windows cannot start, you can use a bootable data recovery tool to recover data because it allows you to access your files without loading the crashed operating system. Tools like MiniTool Power Data Recovery can help recover files in the following situations:
- Windows fails to boot normally
- The computer gets stuck in a restart loop
- You encounter a Blue Screen of Death
- Windows shows startup repair errors
- A failed Windows update prevents startup
- Malware damages important system files
What Should You Do Before Recovering Data From a Crashed Computer
Before attempting to recover files from a crashed computer, follow these precautions to improve the chance of successful recovery.
- Do not reinstall Windows immediately. A clean installation may overwrite data stored on the system drive and make it unrecoverable.
- Prepare a working computer. Since your computer cannot start normally, you need another working computer to create a bootable recovery USB drive.
- Prepare an empty USB drive. Creating bootable media will format the USB drive. Make sure it does not contain important files.
- Get data recovery software. Download MiniTool Power Data Recovery Bootable for data recovery.
How to Recover Data After OS Crashes Using Bootable Recovery Tool
MiniTool Power Data Recovery is a professional data recovery tool for Windows 11/10/8.1/8. It can help you recover files by creating a bootable USB drive. The computer can start from this USB drive instead of the damaged Windows system, allowing you to scan the internal drive and recover important files.
Note that the Bootable Media Builder is not included in the free edition of this software.
Follow the steps below to recover files when Windows won’t boot:
Step 1: Create a Bootable Data Recovery USB Drive
Launch the software, click the Bootable Media Builder icon, and then follow the on-screen instructions to create a bootable USB drive.
Step 2: Boot Your Computer from the Bootable USB Drive

Afterward, open MiniTool Power Data Recovery according to the prompts on your screen.
Step 3: Scan the Drive for Lost Data and Save It
Once you see the main interface of this recovery tool, select the target drive from which you need to recover data and click Scan.
When the scan is completed, you can begin to find and select the needed documents, pictures, videos, audio, etc. from the scan results. During this process, you can utilize Filter and Search features to simplify and speed up the file discovery.
The former involves filtering files by file type, file size, file modification date, and file size. The latter enables you to search for a certain item by using the file name.
For the accuracy of the recovered files, preview them before saving. A variety of files are supported for preview, including documents, videos, audio, photos, and more.
After selecting all wanted items, click Save and choose a location on your removable drive to store recovered data.

How to Prevent Data Loss After Future System Crashes
Although Windows data recovery programs can help recover files from crashed computers, recovery is not always guaranteed. In addition, professional recovery services or advanced recovery tools may require additional costs.
The best method to avoid data loss is to take preventive measures before a system failure happens. Here are some tips to protect your data:
1. Create Regular Backups.
Regularly backing up important files to an external hard drive ensures you can restore your data quickly even if your system crashes unexpectedly.
2. Create a System Image Backup.
A system image allows you to restore Windows, installed programs, and data after a serious system failure.
Tools such as MiniTool ShadowMaker can help back up files, partitions, or systems.
