I just used Acronis 2017 to clone from 1T to 4T as the c: partition was almost full on Lenovo desktop. After cloning to the new 4T drive, C: partition is still 99% full, but PBR_DRV is 100 % empty, and it's current size is 3T. Shrinking option is greyed out from Windows Disk Management utility.
How do I get to resize this particular partition and allocate freed up space to c: partition.
Thanks for any help
