Q: Windows 10 External Bootcamp Partition Missing
Hi,
I just upgraded to El Capitan and now I can't boot into bootcamp (Windows 10).
I have an installation on a TB SSD drive:
Silvettis-iMac:~ Tommy$ diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 250.1 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *256.1 GB disk1
1: Microsoft Reserved 134.2 MB disk1s1
2: Microsoft Basic Data BOOTCAMP 255.0 GB disk1s2
3: Windows Recovery 471.9 MB disk1s3
4: Windows Recovery 472.9 MB disk1s4
I can see the drive in Finder and check files, I can even go to Settings, Start-Up disk and select to boot from it but when the mac reboots it goes to a black screen saying no data partition can be found.
I already checked other posts here but I'm a bit confused regarding my case
Here are a few outputs from gdisk (I disabled the security thing thru recovery mode):
