The error: Paragon Migrate OS to SSD stuck

To improve the computer’s working speed, many users choose to migrate the operating system from HDD to SSD. It can be a tough work unless you use a right tool. Paragon Migrate OS to SSD is designed to help users with the OS migration task. However, some users find Paragon Migrate OS to SSD not working on their computers. It seems to be stuck somehow. One user posted his experience in the forum:

“I purchased Migrate OS to SSD to migrate my OS and after selecting which files and folders to transfer it has been stuck on the preparation for ‘selective copy disc’ for the last 6 hours.

It keeps telling me not to lose hope and to please give it some more time and the disc is still working, but I'm pretty sure it should not be taking this long. I'm moving my OS from a 2 terabyte drive to a 128gig SSD. Any ideas or advice?”

Possible causes for Paragon Migrate OS to SSD stuck

When you encounter the Paragon Migrate OS to SSD stuck issue, it could be caused by:

  • Bad blocks or sectors. You can run CHKDSK to scan the system disk and fix possible errors before OS migration.

  • Different partition tables and Windows boot configuration. You can only migrate MBR disk to MBR disk, and GPT disk to GPT disk with Paragon Migrate OS to SSD. You may convert between GPT and MBR disks to fix the issue.

  • Partitions on the target SSD. You should delete all partitions on the destination SSD before migrating the operating system.

  • Excluded “Users” folder in the migration process. Do not exclude those system folders that would affect OS configuration.
