I have what I believe to be an uncommon issue. I was given the task of “migrating” Windows 10 from an old laptop to a new laptop which also has Windows 10 installed. The owner of both laptops wants this done because she has some proprietary software on the old laptop which she can no longer get the source program for. Trying to do this with free software, I have successfully migrated the old laptop’s Windows 10 to an external USB hard drive. It is bootable on the new laptop. I used Mini Tool Partition Wizard to accomplish that seemingly monumental feat.
The problem now is that I can’t find any free software to migrate her preferred Windows 10 from the USB drive to a partition on the new laptop’s internal hard drive. Free versions of Partition Wizard, EaseUs Partition Master, Disk Genius, and Aoemi Backupper have all failed. I initially wanted to make the new computer dual bootable, but I don’t know if that will even work with two Windows 10 OSs on the same physical hard drive.
Any ideas on which, if any, free software will do the job? Also, step-by-step use of that software would be greatly appreciated.
