Following the post FFFFFFFF problem with hybrid partitioned drive, not able to fix with the guide in other topics, I was able to fix the FFFFFFFF partition problem and managed to boot into macOS, and now how can I recover bootcamp Windows?
Since your drive was hybrid partitioned, I will assume Windows was setup to legacy BIOS boot. You can confirm this by enter the following command in a Terminal application window.
If Windows was set to BIOS boot, then you will get the following response.
Otherwise, you will get the response shown below.
ls: /Volumes/BOOTCAMP/Boot/BCD: No such file or directory
/Volumes/BOOTCAMP/Boot/BCD file does not exist, then post a comment.
Bootfolder is marked as hidden, so the
BCDfile will not normally appear in the Finder application.
One problem preventing Windows from booting would be there is no long an partition marked active in the MBR partition table. You can correct this error by running the
fdisk command, while booted from an external macOS installation disk. The commands to enter are given below.
fdisk -e /dev/disk0 flag 3 quit y
An example is given below.
$ fdisk -e /dev/disk0 fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory Enter 'help' for information fdisk: 1> flag 3 Partition 3 marked active. fdisk:*1> quit Writing current MBR to disk. Device could not be accessed exclusively. A reboot will be needed for changes to take effect. OK? [n] y
If Window still fails to boot, then post a comment.
