I have a 1TB SSD disk with two partitions on it. The first one (and the much bigger one) is a regular Windows partition (drive letter D), the second one (and the smaller one) is a bitlocker encrypted partition (drive letter E). I need to extend this second encrypted partition (E) at the expense of the bigger regular partition (D). The D partition is not a boot partition. I still have a second disk with a boot partition on it.
How do I go about doing this ?
I cannot use built-in Windows tools, because I need to shrink the D partition and move the E partition to the left to be able to extend it, which is not supported by Windows's built-in tools.
I have thought about using GParted on live USB, but I am not sure about the process and whether I won't break anything.
What do you think ? What are your experiences ? Or do you have any other ideas ?
