I just got a new SSD and am wanting to boot my OS off of it. I downloaded EaseUS Todo Backup but when I try to do a system clone I get a message reading, "Not enough unallocated space on the target disk. To make sure the boot ability of target disk, please delete partitions on there first." My SSD and the old hard drive that I am trying to clone are both 1 TB but the hard drive has 426 GB free. It contains mostly games/applications. I made 900 GB of storage on the SSD Unallocated, but I still get the same message. Pretty confused and would appreciate any help.
