When you see the “Your VAIO failed to start Windows” message, you may want to know why Sony VAIO failed to boot. This passage will explain this with sharing easy methods to fix it.
Sometimes, a Sony VAIO laptop may fail to load Windows when you turn it on. This issue usually happens during the boot-up process and prevents the system from starting normally. Many users have reported seeing error messages or the laptop getting stuck on the VAIO logo screen. There are several possible reasons behind this problem, which are listed below.
| Cause | Details |
|---|---|
| 1. BIOS or UEFI Issues | Wrong BIOS settings are the most common reason. Secure Boot might be causing trouble, or the boot mode may be incorrect (UEFI vs. Legacy). You can fix this by changing the BIOS settings or restoring them to default. |
| 2. System File Corruption | If important Windows system files are damaged or missing, your laptop may not be able to boot. You can try using VAIO Care to recover or restore the system. |
| 3. Hardware Problems | A failing hard drive or SSD can stop Windows from loading. These parts wear out over time. Loose connections inside the laptop can also cause boot issues. |
| 4. External Devices or Drivers | Sometimes, devices like USB drives, docks, or outdated drivers can interfere with startup. Removing these devices or uninstalling recent updates may help. |
Before you try to fix any startup problem, it’s important to back up your data first. If your hard drive is failing or your system files are badly corrupted, you might lose important files during the repair process.
A good way to protect your data is to clone your disk using AOMEI Partition Assistant. This tool lets you copy all your files, programs, and system settings to another drive, so even if something goes wrong, your data stays safe. Next, we’ll show you how to use AOMEI Partition Assistant to back up your Sony VAIO.
If your Sony VAIO cannot start Windows, there is a real chance of losing important data, especially when trying to fix the problem. That’s why it is important to back up everything first.
It is better to clone the entire hard drive rather than a part clone like Cloud storage. This will create a full copy of your system, files, and settings. AOMEI Partition Assistant is a reliable tool that can help you do this, even if the laptop will not boot. It lets you clone disks, move the operating system to a new drive, repair system files, and more.
Since Windows does not include a built-in tool for cloning, using AOMEI Partition Assistant is a smart choice. It keeps your data safe and ensures your computer can start properly after cloning. Once the backup is complete, you can begin fixing the startup problem without worrying about data loss.

If your Sony VAIO failed to start Windows, you can try to use the following 3 methods to solve the problem.
Incorrect boot settings in the BIOS may be the reason why your Sony VAIO laptop won't turn on. The boot mode must match the disk type. UEFI needs GPT, and Legacy BIOS needs MBR. If they don’t match, your Sony VAIO laptop may not start Windows. To know more about MBR vs GPT, please click to read more details. You can try changing the boot mode by following these steps:
Step 1. First, shut down your laptop completely. Then press the ASSIST button. This will take you to a screen showing the startup error message.
Step 2. From the menu, choose Start BIOS setup. Go to the Boot tab, then find and select Boot Mode under Boot Configuration.
Step 3. Change the current boot mode. For example, if it is set to Legacy, switch it to UEFI. Press F10 to save the new settings.
After exiting the BIOS, restart your laptop and see if it can power on normally.
According to reports from Sony Forum users, entering VAIO Care (Rescue Mode) may help fix the issue where the VAIO laptop fails to boot. Here's how to do it:
Step 1. When the error screen appears, click on Start VAIO Care (Rescue Mode) at the bottom.
Step 2. Choose Shut down, wait a few moments, then turn your laptop back on to check if Windows can start normally.
Repairing BCD (Boot Configuration Data) files can help fix a Sony VAIO laptop that fails to start Windows, especially if the problem is caused by corrupted or missing boot files. Since you can’t access repair tools inside Windows when it won’t start, the first step is to create a bootable USB. This lets you fix the issue from outside the system.
With AOMEI Partition Assistant, you can use the Boot Repair feature to create a Windows PE-based bootable USB or CD/DVD. Once you boot your VAIO from this media, you’ll see the AOMEI interface, where you can scan and repair system drives, including fixing BCD files. This tool is especially useful when Windows is completely unresponsive and helps restore normal startup.
