Boot camp: Windows option not showing up in boot menu after modifying separate partition
Hello all,
After modifying an unrelated partition (changing from macOS to FAT), now I can't select my Boot Camp drive when holding Alt during startup. The drive still shows up in my Startup Disks field within System Preferences, and I can navigate all the Windows program files within my Boot Camp partition from within MacOSX.
Late 2011 13-inch MacBook Pro, MacOS 10.13.6 High Sierra.
I have since removed the unrelated partition.
I had a suspicion it was an MBR problem and followed some tutorials to no effect.
diskutil list gives the following:
$ diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *750.2 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_CoreStorage Macintosh HD 649.3 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s6
4: Microsoft Basic Data BOOTCAMP 100.0 GB disk0s5
/dev/disk1 (internal, virtual):
#: TYPE NAME SIZE IDENTIFIER
0: Apple_HFS Macintosh HD +648.9 GB disk1
Logical Volume on disk0s2

fdisk weirdly shows the following:
$ sudo fdisk /dev/disk0
Disk: /dev/disk0 geometry: 91201/255/63 [1465149168 sectors]
Signature: 0xAA55
Starting Ending

3: 00 0 0 0 - 0 0 0 [ 0 - 0] unused
4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused
I'm now out of my league when it comes to approaching repair. I'd highly prefer not reinstalling windows to avoid having to install all of my programs again.
Any ideas greatly appreciated!
Many thanks
MacBook
