Use a bootable Linux USB drive to access your non-booting laptop’s hard drive directly, bypassing the failed operating system. This method allows you to mount the internal storage and copy critical files to an external drive without repairing the original installation first.
Preparing the Bootable Media
The most reliable way to recover data from a broken computer is to use a live environment that runs entirely from removable media. You will need a second working computer and an empty USB flash drive with at least 8GB of space. The standard tool for this task is
Etcher or the built-in
Startup Disk Creator on Ubuntu systems. Download a lightweight Linux distribution such as
Ubuntu Desktop or
Linux Mint. These distributions include all necessary drivers for modern hardware and provide a graphical file manager that can read Windows file systems like NTFS out of the box.
Once the ISO file is downloaded, insert the USB drive into your working computer. Open your disk imaging software and select the downloaded ISO image. Ensure the correct USB device is selected as the target to avoid accidentally erasing your current work machine. Click
Flash! or
Create and wait for the process to complete. Verify the checksum if the software offers it, then safely eject the drive. This creates a portable operating system that does not rely on any internal hard drive components.
Booting from the USB Drive
Insert the prepared USB drive into the laptop that will not start normally. Power on the machine and immediately begin pressing the boot menu key. This key varies by manufacturer but is commonly
F12,
F9,
F10, or
Esc. If you miss the window, restart and try again. Some newer laptops require you to disable Secure Boot in the BIOS/UEFI settings before they will allow booting from unsigned USB media. If you cannot enter the BIOS because the screen is black, proceed anyway; many systems still respect the boot override key even if the OS fails to load.
Select the USB drive from the list of bootable devices. The laptop should display a logo and then load the Linux desktop environment. This process may take several minutes depending on the speed of the USB port and the drive itself. Once the desktop appears, you have successfully bypassed the corrupted main operating system. Your internal hard drive is now just another peripheral connected to the system.
Mounting the Internal Drive
Open the file manager application, which is typically located in the bottom dock or accessed via the
Activities menu. Look for your internal hard drive listed under
Other Locations or
Devices. It will likely be labeled with its capacity, such as
500 GB File System, rather than "Windows" or "Data". Click on this entry to mount it.
If the drive contains multiple partitions, you may see several entries. Typically, the large partition formatted as NTFS or exFAT contains your user files. Mounting the drive makes its contents accessible through the file manager interface. If you encounter a permission error, right-click the mounted drive, select
Properties, and check the mount options. In most cases, modern Linux kernels handle NTFS permissions automatically, allowing read-only access without requiring root privileges.
Copying Your Data
With the internal drive mounted, navigate to the folder structure that holds your personal data. On Windows systems, this is usually found at
/media/ubuntu/[DriveLabel]/Users/[YourUsername]/. Inside this directory, locate folders such as
Documents,
Desktop,
Downloads, and
Pictures.
Connect an external hard drive or USB stick to an available port on the non-booting laptop. Wait for it to appear in the file manager sidebar. Select the files you wish to save. For large collections of photos or documents, it is safer to copy entire folders rather than selecting individual files to prevent partial transfers. Drag and drop the folders onto the external drive’s icon, or use the
Copy and
Paste commands.
Monitor the progress bar closely. Do not disconnect the external drive until the transfer is fully complete. If the transfer fails or the system hangs, the hard drive may have physical sector errors. In such cases, refer to our guide on
Can Corrupt or Physically Damaged Sectors on a Hard Drive be Written Over? for advanced diagnostic steps. Once the copy finishes, verify the file sizes match the originals before shutting down the system.
Safely Shutting Down
After confirming your data is secure, you can shut down the laptop. Click the system power icon in the top-right corner of the screen and select
Shut Down. Allow the system to power off completely before removing the USB drive. You can now attempt to repair the original operating system or replace the hard drive, knowing your files are safe. For more complex recovery scenarios involving damaged drives, consider exploring
Options Beyond DDRescue to understand alternative imaging tools.
Frequently Asked Questions
Will this method delete my files?
No, using a live USB environment only reads the data from your internal drive. It does not format or erase any partitions unless you explicitly choose to do so within the file manager tools.
What if my drive uses BitLocker encryption?
If your drive is encrypted with BitLocker, you will need the recovery key to decrypt it before accessing the files. Without this key, the Linux system will see the drive as raw, unreadable data.
Can I fix the laptop after copying files?
Yes, once your data is backed up, you can reinstall Windows or replace the faulty component. Having a backup ensures you do not lose information during the repair process.
Why is my USB drive not showing up in the boot menu?
Ensure that Fast Boot is disabled in the BIOS settings and that Secure Boot is turned off. Some older motherboards also require you to change the SATA mode from RAID to AHCI to recognize the drive properly.
Is it better to use ddrescue instead?
For simple file recovery, a graphical Linux interface is faster and easier. However, if the drive is failing physically,
Recovering files from non-booting laptop suggests using ddrescue to create a sector-by-sector image first to minimize further stress on the hardware.
