I recently had a problem with my laptop. I was running Windows 7 and the system would often freeze when I was using it. Eventually it got to the point where it would not boot up at all. I tried using the Windows 7 recovery disk and reinstalling the operating system but the problem persisted.
Update the version of Windows on your PC. After recovering the data, convert the disk to a basic disk in "Disk Management". Use the command to reactivate the invalid disk. Import dynamic information from disk to another computer. Use third-party tools to repair invalid dynamic disks.
