When I hold alt and start my computer, I see my Mac HD and two Windows partitions, not one. Only one works though, the other goes to a setup screen. It's leftover from a failed windows installation. The problem is, I have no idea how to get rid of it. Any idea where those files are or how to edit the boot manager so it doesn't show up? Note that I don't actually have two bootable windows partitions, just one... Code: /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh Scratch 400.0 GB disk0s2 3: Microsoft Basic Data Windows Scratch 99.8 GB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk1 1: EFI 209.7 MB disk1s1 2: Apple_HFS Macintosh HD 85.9 GB disk1s2 3: Microsoft Basic Data Windows 33.8 GB disk1s3 Disk 0 is my 500GB HDD, disk 1 is my SSD. Both have two partitions: an HFS one and an NTFS one. The ones on the SSD are bootable, the ones on the HDD are not. So where's this mystery 2nd bootable windows partition?
