Therefore, here we suggest using MiniTool Partition Wizard since it is a more convenient solution. In PC there is only one active partition and system partition or boot partition must be primary and active. In this case, you must mark the partition within boot files active to ensure the computer runs properly.

In order to solve the issue, please reset your system partition active. Step 1: Select the wrong active partition. You could see there are many partition functions in the left pane and please select Set Inactive. Step 3: At last, you will go back to the main interface of MiniTool Partition Wizard again and click the Apply button to make these changes effective. What you need to do is to check the disk surface. If bad sectors exist, this tool will mark them red. On the contrary, healthy sectors will be marked green.

Once bad blocks are found, you can use the chkdsk tool to shield them. If there are many bad blocks, in order to avoid data loss, please back up the significant data on the target disk. Fortunately, MiniTool Partition Wizard has those two functions: copy partition and copy disk. Select "Repair your computer". Click "Troubleshoot" on the Choose an option screen. Then, on the Troubleshoot screen, click the "Advanced" option. Step 5. If not, continue. Repeat the steps above to find the Startup Repair options by using the Windows installation disc.

This time, select "System Restore". Follow the System Restore Wizard instructions and select the appropriate restore point. We hope that these solutions are helpful. Otherwise, I am afraid you may need to consider to do a clean Windows Installation or replace the PC hard drive. Performing a clean installation of Windows will completely remove Windows from your PC and install it again from scratch.

A clean installation will erase all of your data, so you must back up your important files in advance, or you will lose them all. If you can't access your data to back them up, use professional data recovery software - EaseUS Data Recovery Wizard to recover data from a computer that won't boot.

Prepare an empty USB. If you have important data on it, copy the data to another device. When you create a bootable disk, the data on the USB will be erased. Select the USB drive and click "Create" to create a bootable disk. For most users, it works well when they restart their computer and press F2 at the same time to enter BIOS.

Press "F10" to save and exit. Select the drive you want to scan to find all your lost files. Recover data from the computer or laptop. After the scan completed, you can preview all recoverable files, select the targeted files, and click the "Recover" button to restore your files. You'd better save all of the recovered data to another place to avoid data overwriting.

If the clean installation fails neither, you're most likely facing a hardware issue with your hard drive. Then, recover your data from the corrupted hard drive and replace the hard drive.
