This should be easy....I must be missing something. I had a 500gb hard drive in my computer and replaced it with a 1TB hard drive. I did a quick format of the new drive to make a simple volume of 1TB, then restored the computer from a backup image. The computer runs fine, except the backup software left the extra 500gb of the new hard drive as unallocated space. I want to extend drive C: to include the unallocated space. But when try to merge or extend, I get a warning that if I do this, the computer will not longer be bootable. What is the proper sequence of commands for this? Thanks.
Just ignore the warning and extend the partition with the Windows disk manager, or with a Paragon program. If something goes wrong (not probable), you still have the image you restored, I assume.
Windows wouldn't work. But in Partition Manager was able to grab the image of the C: volume and drag it over the unallocated space & apply changes. Seems to have worked. Just not obvious at all how to do it. Thanks. Problem solved.
