Converting dynamic disk to basic

While trying to install Windows 7 on one of my old SATA disk I stumbled upon this dynamic disk problem.
It means, that you cannot install Windows on a dynamic disk type. Apparently I've created a dynamic SATA disk type somehow...
To change it to basic. Boot up the Windows 7 cd and go to the part where it finds your harddisk but fails to install or delete.
From here, call up the command prompt and call up the DISKPART tool.

Type:
- diskpart

At the DISKPART prompt, type:
- list disk

Make note of the dynamic disk you want to convert to a basic disk.
At the DISKPART prompt, type:
- select disk #number_here

At the DISKPART prompt, type:
- detail disk

For each volume on the disk, at the DISKPART prompt, type:
- select volume #number_here
and then type:
- delete volume

At the DISKPART prompt, type:
- select disk #number_here
Specify the disk number of the disk that you want to convert to a basic disk.

At the DISKPART prompt, type:
- convert basic

There you go. Continue your installation and you're good to go.
