Just upgraded the boot drive on my HTPC from 128GB SSD to 480GB SSD using CloneZilla. Back in the day, my weapon of choice was Norton Ghost but it was discontinued. CloneZilla works even better/faster/easier than Norton Ghost.
I wasn’t able to get the UEFI .zip files to boot, but downloading the .iso file and using Rufus to “burn” the iso to the same USB key I was struggling with, worked like a charm. It’s weird cuz the computer is UEFI and in the end using the iso method it was also using UEFI.
Regardless, the clone took about 10 minutes for about 93GB of data. Restarted the computer and Windows boot right up none the wiser. Only thing I had to do was extend the partition to take advantage of the full drive, else it was still showing a max of 115GB.
Going to do the same on my server now, going from 128GB SSD to 1TB SSD.
