Can anyone help me with that !!
I Really need to access mac os and restore it ..
You may not add or subtract partitions in a Boot Camp installation, but you know that now.
Except for your C:\ drive all the remaining drives are empty, it would appear that you no longer have an OSX partition. It also appears that the recovery system has been hosed. You may have to use Internet Recovery (if available) for your Mac. How old is your Mini and what version of OSX did it come with when new.
And do you have any backups?
May Mac mini is ( Late 2012 )
OSX I don't know because I bought it used 😟.. But I upgraded it lately to the latest version ..
And I don't have any Backups ..
When you installed W8.1, you corrupted your disk partition tables.
1. You can try OS X: Installing OS X on an external volume - Apple Support and booting from such a disk.
2. If you have a second Mac, you can try to Share files between two computers with target disk mode - Apple Support to look at the partition table and try a recovery.
3. You can also try Internet Recovery (OS X: About OS X Recovery - Apple Support) to rebuild your partition table, but you may lose all your data.
I Have tried the internet recovery and disk utility , but it failed ( even to repair )
the Mac Os Partition was (ExFat) format ..
at the end i erased the whole disk and reinstalled Mac lion..

No it was not.
(ExFat) .. That what was written in Disk utility..
OSX will not run on an ExFat partition. (It won't even install)
EXactly,
thats why my Mac OsX stopped working and even disappeared from the boot screen in addition to Recovery partition ..
its formats was corrupted.
Even my windows on bootcamp didn't start , till i reinstalled it. And once i installed (apple support drivers) then restarted.. Windows stopped again.
I Had no Mac OsX .. No recovery..
i Used internet disk utility recovery, faild to repair .. ( exfat) ..
so i erased the whole HD and reinstalled Mac Lion OsX 10.8
You are going to have to reformat the disk drive as a single partition formatted as Mac OS extended with a GUID partition mapping and then reinstall Mountain Lion 10.8 on it.
Once you have done that you will need to recreate the Boot Camp portion again and reinstall Windows.
Since you have no backups that means all of your data and applications which are no part of OS X will be lost.
You are now probably aware of the value of backups. You might want to consider implementing a valid backup plan for your Mac.
Sure, This is the first time not to have a backup, since I moved to Mac OsX .. Lately
I need help !! Turned my Disck into dynamic, Lost Mac Os ..
