Unlock and set the disk you would like to use as start up disk 4. Reboot Is the answer helpful? Related I installed Windows 10 with BootCamp but the OS would not recognize the enclosure. JetDrive fails to restore operating system and the partition of the original drive is grayed out. What can I do? The PCBA of USB to SATA adapter falls out of the JetDrive (420/500/520/720/725) enclosure. Is this normal?
