I am attempting to create a 100 GB partition for windows 10 on my macbook air via Bootcamp Assistant. I have been stuck on "partitioning disk...", with the load bar completely full for some time now. I have a 64 GB USB drive inserted, which I believe was necessary for the partition.
Additionally, I have just installed a 480 GB SSD from OWC. When using disk utility my SSD, the USB drive, the iso images for windows 10 as well as the boot camp partition show up. However, the bootcamp partition is in light grey and says it is not mounted.
If anyone could let me know what I am doing wrong or what I can do to fix this issue it would be greatly appreciated.
