Converting Parimary partition to Logical drive

There are many threads and numerous posts on this but I would still like to believe that the issue I am facing is unique

I have the following:-

System - 100 MB
C: - 400 GB - Primary
E: - 50 GB - Primary
D: - 50 GB - Logical

The option to "convert Primary to Logical" in PW Free edition is Greyed out hence unavailable. This I presume is because it is the extended boot partition.

Currently all I want is to create:-

System - 100 MB
C: - 50 GB - Primary
D: - 450 GB - Logical

Thank you

I wanted to have a 450 GB logical drive where I could store all my data. Coming straight from XP, I wanted to have a C: drive where I could install/re-install OS and still rest assured about my data which is on another logical drive.

Currently all my data is backed up...

thanks greg and ignaz and sorry about not posting the screen-shot; i do not have that machine currently with me. will have it later in the day

ignatzatsonic, as far as what I understand from your post is, extended primary disks are as safe as logical drives as far as data security is concerned.

i need to read some literature about differences between extended primary partitions, logical drives, their pros and cons. if possible, please provide a link of any related article(s) that you may have.

Thanks so much

i watched both the videos

using PW, will perform the following steps:-

1. decrease size of C: to 50 GB
2. create the resulting free space (350 GB) to form a new drive say F:
3. try to extend F: to take up space of D: & E: to make it a 450 GB drive

Will post the results along with the screen-shot

Thank you

when you gave the video links above, i thought you want me to try it myself first...

anyways will post the screenshots before these steps
