Hi

For some reason I didn't get your replies on your other thread.

You can only extend into Unpartitioned Space to the right of the partition you are extending. You deleted the D: drive, but that space isn't Unpartitioned Space. Because you can only have a max of 4 partitions on an MBR disk, the last one is typically created as an Extended Partition, which lets you create additional Logical Drives inside of it. This is a goofy configuration if this is how it came from Dell. You need to also delete F:, then delete the Extended Partition. Then you can extend C: because you will have Unpartitioned Space where the Extended Partition was.

there are 3 situations that"Extend Volume" will be grayed out:

1.The partition users want to extend is not a NTFS partition. Microsoft says extending volume feature in Disk Management only works to a raw or NTFS partition.

2.There is no unallocated or free space on hard disk or the space is not contiguous and after the partition which needs extending.

3.Users want to extend a primary partition, but, instead of unallocated space, there is just a free space right after the target partition. 

you are just in the situation 3. therefore you need to move unallocated space outside extended partition before you can use DIsk Management to extend C:d rive.

Thankyou for the info

I will extend C partition by deleting F. To delete F I first checked for hidden and System files. I then removed the page file setting on F partition, in advanced settings.

Actually, the operation to extend your C drive can be simplified with a third-party software. Like AOMEI  Partition Assistant, you can use it to resize C drive by merge a nonadjacent unallocated space  into C drive. (Windows built-in software can only extend C drive when there is an unallocated space right behind it.) Or you can use AOMEI  allocate the free space of other partition into C drive so to extend it directly.
