Q: Bootcamp wont boot to Windows after resize partition

I've been using osX (now macOS) and Windows 10 on my computer for several years.  A few days ago I went to Disk Utility to create a new partition. The new partition took space from macOS and none from the Windows 10 partition. But when I hold down alt option key during startup I no longer have the option to boot to windows. If you can help me, thanks in advance.

 

Here is the output from sudo gpt -r -vv show disk0

 

gpt show: disk0: mediasize=750156374016; sectorsize=512; blocks=1465149168

gpt show: disk0: Suspicious MBR at sector 0

gpt show: disk0: Pri GPT at sector 1

gpt show: disk0: Sec GPT at sector 1465149167

    You hosed up the WIndows partition. The only way to work with the windows partition is using the BootCamp utilities, not with macOS disk utility or Windows.

    I suspect yo need to reinstall Windows/bootcamp.

     

    I requested you post be moved to the Boot Camp forum

    Boot Camp

    The only option boot camp assistant seems to give me is to erase the windows partition. I might do that, because I don't like Windows and there doesn't seem to be a better time than now to get rid of it. I can still access all of my files from the windows partition so I'm just going to back them up to a USB drive and then erase windows.... Unless anyone has a fix.

    Please post the output of

     

    diskutil list

    diskutil cs list

    sudo fdisk /dev/disk0

     

    Did Disk Utility warn you about issues with Windows if you partitioned the disk? This is from Mavericks.
