As if that wasn't enough, I also upgraded Yosemite to El Capitan Beta 1.El Capitan worked, but when I discovered that the Bootcamp-partition didn't show up in the boot options, I tried to fix it with testdisk, and even gdisk. The latter, which totally screwed up my mac-partition. I got the question-mark when I rebooted, so nothing was functioning. So I installed Windows 10 and erased the bootcamp-partition. I can live with bootcamp-files gone, but not the Mac-files gone. Now, I've installed Mac onto an USB. This is very, very slow, but it works. The prob

Some people (me included) prefers to have their data in a separate, dedicated partition rather than using the same partition as the OS. unable to Here I explain how to achieve it. 1- Use the Boot Camp Assistant for creating a standard Boot Camp configuration. The size for the Windows partition should be the neccessary for Windows and your Windows Applications only, as your data will be stored in a different partition. Follow the Assistant until you get a Windows installed and working via BootCamp. NOTE: These instrucctions assume that you've chosen NTFS file format when asked by the Windows installer. unable to open 2- Use the WinClone application for creating an image file of the Windows partition. WinClone lets you select the partition and will store it in a single file that can be restored anytime. This is a MANDATORY step, even if you have some other way for creating backup files / images. You'll see why later. 3- In Mac OS open the Disk Utility. Resize the Macintosh HD partition in order to leave an emtpy space between this partition and the Windows partition. This empty space will hold your Data partition, so leave as much space as you want for it. Then create a new Partition in the empty space. Detailed steps: - Open Disk Utility - Select your hard disk from the left list. - Click Partitions - Click the first partition (Macintosh HD). Drag its lower-right corner in order to leave an empty space. - Click the [+] button below the partition schema. A new partition will be created filling the empty space. - Click Apply. 4- Reboot your Mac. This is neccesary so each partition could receive their proper id acording to their order in the disk. 5- Format the new partition so it can be accessed from Windows (NTFS or FAT32). 5A- If you want FAT32 in your Data partition: - Open Disk Utility - Select the second partition from the le
