How do I merge partitions?

[Jessica]

How do I merge partitions? I have just install a new SSD drive as my C Drive. My old HDD was partitioned into two drives (C and D). How do I merge the partitions so that I have one partition (D Drive)? Any help will be appreciated. Thanks

You need to backup all important data off of the second partition on the HDD, and then delete that partition. Then, using Disk Management, or a third party app like Partition Wizard, you can resize the first partition to fill the entire HDD.

Thanks. All OK now. I used a program called EaseUS. cheers...

If you still have the old OS on the HD, then the correct way to remove it is to Delete it's partition in Disk Management. You may need to first Mark Partition as Inactive - Windows 7 Forums.

I would move all data off the old OS partition before doing this, then afterwards resize the data partition into the space using Partition Wizard Resize Partition - Video Help.

Use the PW boot CD which never fails while all others can fail except Disk mgmt.
