How many partitions does this system have? (If not sure, run a command prompt - diskpart - sel disk 0 - list part)
For a managed boot, the provisioning action attempts to add a partition. But, the MBR can only contain 4 primary or 3 primary + 1 extended partition.
Hello Frank, I have one primary and three extended partitions. It works after I deleted the three extended partitions. Thanks a lot for your help.
