I would like to replace the HDD in my laptop with an SSD without having to rewrite Windows. Can I simply connect the SSD and the HDD to my desktop PC and push in the Windows Explorer, the data of the HDD on the data of the SDD? Or is there complications?
For this you need the program "Acronis". Otherwise, cloning does not work. Acronis you can download the on the Internet
No, it also uses the boot sectors etz. However, you can clone the plate eg with hdclone, then works without problems.
Some manufacturers of SSDs offer free cloning programs for this.
Acronis Live Boot would be an alternative.
For both options both plates can be connected in the desktop.
But about the Explorer that is probably nothing.
Hdclone should be perfectly adequate for a simple cloning process.
