hi everyone. i use win 7 ultimate sp1 x64. i wanted install windows 8 and make dual boot on my machine. before my c: volume was 267 gb the D: volume was 605gb and E: volume was 59gb. so i began shrinking. on c partiton i had less free space so i thought i could shrink volume d and i did it. new unallocated partition was nearly 117 gb. i created it as a new volume and then i faced thatwin 8 cannot install there i had to shring the View attachment 27285 volume c:. with 3rd party application i resized c partition by adding the new 117 gb volume into it. everything was fine and my c disk was 384 gb after resizing it. then i decided to shrink the volume c: to make a new partition on that drive to install windows 8. i ran disk mgmt toolof windows and shrunk c: . but after a while an error message appeared it closed. and that 117gb free space now lost on my pc. but it seems on diskmgmt connected to my c volume. im adding a screenshot so u could see it. now my c volume shows total 281 gb not 384 gb. cannot see that partition anywhere and i want to get that partition back how i can do it. only disk mgmt shows it but it shows its as a part of drive c:. i want to split them as before they were a separate partitions i have done my backup but i think there may be a way without re-installing windows and without deleting c: partition. please i need it immediately.
