I have deleted the Recovery HDD for Mac OS, when I have installed Windows 8.1, because Windows 8 didn't allow me to have more than 4 partitions. Everything worked fine.


Last evening I have upgraded to Yosemite and Windows 8.1 partition disapeared form BootCamp. I see disk04 in Disk Utility, but I can't see also the 2 NTFS partitions of it.


What can I do to be able to boot also on my Windows partition?


Thank you a lot, Loner T!

Yosemite becomes unpredictable in non-standard configurations. If you notice you have a Recovery HD now, even though you had deleted it to get around the 4-partition MBR limit prior to Yosemite. The best method is to use Testdisk and find deleted partitions. The referenced thread deals with a "standard" 4-partition setup and the issues due to Yosemite upgrade. The Testdisk and GPT Fdisk tools are needed to start the analysis.


Test disk can scan the disk sector-by-sector to find deleted NTFS information or backup NTFS sectors to help rebuild partitions.
