Don’t know how to fix GPT partition table windows 7/8/10/11? Refer to this article to get the specific steps to fix GPT partition table in Windows 7 easily and effectively.
Many computer users may find that a GPT disk cannot be opened while they use a computer. This situation usually occurs after an unexpected power failure, forced shutdown, etc. These operations can result in loss of data and corruption in the hard disk partition table or the primary boot sector.
As mentioned above, when the partition table GPT is damaged, the disk may not be able to be opened and thus, you’ll suffer from great data loss. Here we recommend that you use AOMEI Partition Assistant Professional to repair the GPT partition table. It can help you make a bootable PE disk, and repair the computer in PE mode. AOMEI Partition Assistant is a powerful, professional-grade, lossless partition tool that is perfectly compatible with the current mainstream operating systems on the market. It provides simple, easy-to-use disk partition management. In addition, AOMEI Partition Assistant also provides you with many useful functions like partition splitting, SSD 4k alignment, and free space allocation, etc. Follow the guide below to solve this problem.
If the problematic disk is not a data disk, you can directly open the AOMEI product to use it; however, if the problematic disk is a system disk, first, you need to make a bootable PE disk and check and repair the system partition in the PE environment. Here, we take a damaged system disk for example. What you need to prepare is a blank USB flash drive (preferably larger than 8GB). The specific steps are as follows:
Step 1. Download, install and run AOMEI Partition Assistant. Connect your USB flash drive to your computer and make sure it can be detected. Click “Tools” in the top toolbar, and choose “Make Bootable Media”.
Step 2. Click “Next” to ensure creating WinPE bootable media.
Step 3. In the Make Bootable Media Wizard, tick “USB Boot Drive” and click “Proceed”.
Step 4. After you create the bootable media, don’t remove the USB drive, restart your computer and follow the prompts to enter Win PE. Then, run AOMEI Partition Assistant, click the disk you want to recover and select “Partition Recovery Wizard” on the left panel.
Step 5. Select the disk which contains lost partition and click “Next”.
Step 6. Select “Fast Search” in the pop-up window. It’s recommended to select this option for the first time. This option takes less time. If you cannot recover the lost partition, you can select “Full Search” later.
Step 7. Then, select the lost partition to recover and click “Next”. If you are not sure, you can click “Explore files in this selected partition” to view the files in the partition. And click “Finish” at last.
After these operations, you can check whether your partition is restored or not in Disk Management or File Explore.
After your partition is restored, do the following steps in AOMEI Partition Assistant:
Step 1. Right click the disk you want to repair and then select “Rebuild MBR”.
Step 2. After that, choose the proper MBR type for Windows 7 in the popping up window.
Step 3. Then, click “Apply” > “Proceed” to commit the change.
Then you can apply AOMEI Partition Assistant to check bad sectors, and the step by step guide is below:
1. Right click the partition you want to check and select “Advanced” > “Check Partition”.
2. In the pop-up window, select the way of checking errors to perform. There are three choices, simply choose the last one “Check whether there is bad sector on the partition”. And click “OK” to continue.
3. After that, click “Start” button to check.
After checking the bad sector, if the hard disk has a bad sector, you’d better backup data in advance if possible. If there are important data in the bad sectors, you should send the hard disk directly to the professional data recovery center to recover the data. In addition, not all bad sectors can be fixed.
