I have a MacBook Pro 13" Late 2011.

I have an SSD with a macOS High Sierra, and a BootCamp partition which I installed years before. I want to resize the BootCamp Partition to give it more space to work with. As much as possible I did NOT want to have to delete my windows partition first, then install it again. Upon searching, I across this guide which offers several solutions on resizing the BootCamp Partition Live. I think my best option was to use MiniTool Partition Wizard, I just had to make a blank space, boot in Windows, install the program, and then expand my Windows partition with the free blank space I just made.

I freed up space in Disk Utility by using "Partition", left it to do it's magic. But when I reset, my BootCamp Partition was no longer seen at start up! I also went to settings and then set the StartUp Disk to my BootCamp partition:

But when I reset my laptop, it showed me the "No bootable disk" error.

Now, how do I make my BootCamp Partition Visible again?

Any leads and help would be very much appreciated. Thank you.

    You macOS installed twice. This is not typical for a Mac with an Boot Camp installation of Windows. Could you add the output from diskutil list to your question? – David Anderson Jul 23 '18 at 9:50
