Merge two partition in windows without using third party S/W

Before merging the partition please ensure that the file system should b NTFS.

1. Make sure you backup partition #2 (in my case, the logical drive) that you want absorbed into partition #1 (boot drive). The data in #2 will have to be erased.

2. Go to the command line (Start > Programs > Accessories > Command line) and type DISKPART

3. At the prompt line (DISKPART>), type:
- LIST DISK
- SELECT DISK [enter disk number]
- LIST PARTITION
- SELECT PARTITION 2 (or number of partition to be absorbed)
- DELETE PARTITION (this will format the partition to be absorbed, so make sure you have a copy of your files elsewhere)

4. Now, to extend partition #1:
- LIST VOLUME
- SELECT VOLUME [enter number of the volume assigned to your C drive]
- EXTEND (this will resize partition #1 to take up all the unallocated space in the hard drive)

5. Type EXIT to leave DISKPART
