Q: Cannot boot from Bootcamp
Hi all,
I have recently replaced my old hard drive for a SSD. In my old drive I have one partition with OS X Yosemite and another with Bootcamp. Since the new drive has less capacity than the old drive, I decided to clone the partitions instead of cloning the whole drive and since then, I cannot boot from the bootcamp partition.
I understand where the problem is. Since the whole drive was not cloned, the MBR was not copied from the old drive to the new one (please, somebody correct me if I'm wrong). What I am trying to do now, is to fix the issue. Here is all the information I believe it is relevant:
- I can see the Bootcamp partition in Finder and access the files.
- Bootcamp appears as an option in System Preferences -> Startup Disk. However, when I select it and Reboot and black screen with a blinking cursor it is all that appears but Windows actually never boots.
- Bootcamp does not appear as an option when rebooting and pressing option.
- If I connect my old drive (via a USB case) and reboot pressing the option key, the Bootcamp partition there appears as an option to boot.
- I have followed the steps depicted here but it didn't work.
Attached, some outputs of fdisk and diskutils
