I've tried to use boot repar, from an usb-live ( i've followed this guide https://help.ubuntu.com/community/Boot-Repair ), i have also removed the secure-boot and set the uefi mode, but it still not work.

Boot-repair give me this log error

Microsoft has dynamic partitions. It is proprietary to Microsoft & does not work with Linux. But its main purpose was a work around for the old MBR limit of 4 primary partitions.
But with the new gpt partitioning used with UEFI, there is no real limit on partitions (its 128, but can be user changed).

But for some reason you have dynamic partitions with gpt partitioning.
Just to understand, how does that happen?

Logical Disk Manager (LDM) metadata partition (Windows)

Many with old BIOS/MBR configurations have done it and Microsoft does not have an undo. It recommendation is full backup, erase drive, and reinstall.
But with MBR there are several third party tools that have worked. But good backups still required, just in case.
But have not seen many gpt dynamic partition configurations and do not know if or how well third party tools work.

You may be able to see dynamic partitions from Linux:
sudo apt-get install ldmtool

Microsoft's official policy is a full backup, erase dynamic partitions and create new basic partitions. There is no undo.
Dynamic volume is a Microsoft proprietary format developed together with Veritas/Symantec for logical volumes.
You may be use a third-party tool, such as Partition Wizard MiniTool or EASEUS to convert a convert a dynamic disk to a basic disk without having to delete or format them.
I've never used any of these and so I can't be sure they will work.Be sure to have good backups as any major partition change has risks.
