Convert Dynamic HDD to Basic

Dear all,

I have a computer installed with windows 2008 R2, I try to format the computer and I found the disks configured as Dynamic, so how I can convert those HDD to basic?

I believe, in doing so, you may lose data.

Look here (if not seen already) however: >

Are you trying to install the second Operating Systems?

After you convert a basic disk to a dynamic disk, you cannot change the dynamic volumes back to partitions. Instead, you must delete all dynamic volumes on the disk and then use the Convert To Basic Disk command. If you want to keep your data, you must first back it up or move it to another volume.

For more information about basic and dynamic disk, please read

As noted above, there is no provision in Disk Management to convert a dynamic disk to basic without loss of all data.

It is, of course, ALWAYS a good idea to have a complete backup of your data before making any changes to the partition structure [it's a good idea to always have a complete backup PERIOD -- whether or not you're planning changes].    

... but you CAN change the disk to a basic disk without data loss using this utility:
Disk 0 is mirrored with Disk 1.. you can always go to diskpart and then
sel disk 0
sel disk 1

But only do this if you don't care about what is on the drives.
