The Original ACER HDD (1Tb) DISK 0 has: 13GB recovery partition, / System reserved 100Mb NTFS (system, Active, primary partition), / Acer C: 458.95 GB NTFS (boot, swap file, crash dump, primary partition), / Data

After Migration with Samsung Magician the Samsung SSD 870 QVO DISK 1 has: I: 100Mb NTFS (Active, primary partition), / Acer J: 458.95 GB NTFS (primary partition), / Data H: 472.47 GB NTFS (primary partition)
After changing boot sequence in BIOS.
Start up with SSD boots the pc and it will give me a dark blue screen with text: building desktop
After that it hangs. I only can scroll with my mouse over the blue screens.
What have I done wrong?
