On my MacPro i have a dedicated ssd for my High Sierra Install and a separate internal one for a Windows 10 install.
In high Sierra i made with Winclone a copy of the internal Windows 10 ssd succesfully. When my Windows ssd corrupted i needed Winclone to put back the image on the dedicated SSD. This actually went great, but when booting into the Win10 install there comes up a screen with the text INACCESSIBLE BOOT DEVICE and iT does nog continue.
Please tell me I van save my Windows 10 install .
