how to extend dynamic boot disk

Hi Experts,
I have a server that has only one disk with one partion, C drive. The C drive has the boot partion and all the applications on it. I need to expand the C partion to 100 GB. I attached another disk to the server and make the second disk dynamic disk with NTFS.

How can I expand my C ( disk 0 ) to use some space on the new disk?

I also converted disk 0 to be dynamic as well.

There aren't many applications that can work with Dynamic Disks (in fact, I know of none).  Do a complete backup then restore to a new drive.  But why do you need such a huge C: drive?  10 GB should be more than enough... what does this server do?  Why not create a second partition for whatever you need?

Could you explain to me why there aren't many applications that can work with Dynamic Disks?
Are you suggesting using basic disks?

Lee W, MVPTechnology and Business Process AdvisorCommented:
Dynamic disks are a microsoft concept - not an industry standard.  You should always use basic disks unless you have a good reason not to (need to use a software RAID (hardware RAID is preferred), or need to use a GPT based disk for a partition larger than 2 TB).

But you can't convert back to basic easily - without wiping and reinstalling/restoring.

Leew is right with his suggestion about dynamic drive. I assume application mentioned by him are mostly partitioning and backup tools as other software works fine with dynamic drives. But, if you extend the current drive to new drive via dynamic extension then you set yourself into biggest trap. Imagine that your original HDD where C: is located fails, and you need recover from backup - here you could have big
As you have converted the current C: drive into dynamic volume you need a third party software to convert it back to basic. And the best way still would be cloning C: drive to new bigger HDD.
I know software that can do this easily: Drive Backup 9.0
You need Server Edition. This will create backup of dynamic drive (actually C: volume) and let you to restore it to new bigger drive which must be in basic state (convert it back to basic via Windows Disk Management as it allows conversion of empty hard drives).
As restore is completed reboot server to new HDD. BTW, this method allows you to extend the existing partition during restore to new drive so taking all or selected free space for newly created partition.
And finally, you will have good backup.
Note, in case you have DC\AD on this server then use first NTBackup tool to save system state. It could be useful.
