I can't convert my dynamic disk partition to basic.

Hi everyone!

Hope you're all right and in a good state. 

I've run window 8 on my PC I wanted to change it to windows 10. after booting the USB flash I run the basic booting installation. But as it is obvious a windows OS won't run in a dynamic disk partition. I formatted the windows drive didn't get any partition. I played around with the repairing options of the PC. I run the cmd and disk part options but didn't find something to convert my dynamic disk to basic. Is this possible to plug off my HDD and backup my data to an external HDD or I should format it losing all my data. And now there is no OS on my laptop. I'd be glad from your answers. And by the way I am not native in English hope you'd ignore that.

Sorry for the bad news -- but there is no reliable way to convert Dynamic Disk to Basic Volume without losing data.

If you read the MS articles about this, they all say to copy everything OFF the Dynamic Disk to external storage and then do the conversion, and when done, copy everything back.
