Mar 26, 2015 4:42 AM in response to Hyujnae_Limby Loner T,1. Bootcamp Assistant does not need to be downloaded again.
2. If you want to re-install Windows, and it is already installed, use BC Assistant to remove the current Windows installation. Please ensure you have a backup of all your important files first.
3. If after Disk Repair, you still cannot partition using BC Assistant,
a. You may not have enough contiguous disk space. This mean backing up your current OS X installation, erasing your internal hard drive, and restoring
from backup, or,
b. you have manually partitioned you disk, which cannot be used by BC Assistant, because it exceeds some internal limits of number of partitions necessary
for BCA to work.
