Macbookpro 2011 bootcamp clone not booting in legace mode

Winclone

Hi all
I have Cloned my bootcamp partition from my old HDD to my SDD on my Macbookpro 2011 and the problem is that after a successful clone, the Bootcamp partition doesn’t boot in legacy mode (showing me No bootable device found Insert a floppy disk and …) BUT if I change the boot mode to EFI , windows boots up and everything works except that the sound driver wont work .

From what I gather my mac doesn’t support EFI booting and I have to make the windows boot in legacy mode.

This is a screenshot of my diskutil list:

I would really really appreciate any help on how to make my already installed windows bootable in legacy mode.

Thanks in advance

This is a known issue. Try restoring the image, switch to EFI mode before booting to Windows. the sound driver should then work fine.

Do you mean switch to legacy mode?

There is a known workaround to get sound working in EFI mode. The safe way to do this on Macs is via a registry override with Windows test signing mode enabled.
