Hello,
I have a ASUS G73s laptop with a 500GB harddrive.It is partitioned into C and D.I tried to combine them into one but the delet command is not highlightable in disk management.Please help

you could use a third-party partitioning program, like g-parted, Partition commander, Partition magic or others.

Why do you want to do this? There are very good reasons for having two partitions on the drive.
