So, i installed windows 10 on my iMac, i problem took big wrong turn because now im stuck in windows. I have attempted to press option, but when the options come up i only get the windows option. I have an audio problem and now i cant find my Mac OS, so fixing it is pretty. Im considering delivering in my mac to the nearest service center unless i can fix it myself!
iMac (27-inch Mid 2011), windows 10
If this is not too late, can you check Device Manager for any unknown devices (yellow triangle with exclamation mark)?
Run Resetting the System Management Controller (SMC) on your Mac - Apple Support and How to Reset NVRAM on your Mac - Apple Support and check fi the Alt/Option key will let you choose OSX. If the W10 upgrade overwrote any other partitions, you may need toHow to install OS X on an external drive connected to your Mac - Apple Support and boot from this external OSX disk to diagnose your partitioning issues.
Ok. So SMC and NVRAM, if still no OSX then OSX on external drive? Thank you so much! Will test this out and come back to you!
Can you download GPT Fdisk from http://sourceforge.net/projects/gptfdisk/ and unpack it on the Windows side? Let us check if you have OS X or not.
Can run the following in an Admin CMD window? Please notice the drive number is "0:" without the double quotes.
Not really understanding your commands?
In the CMD window with Admin rights (you should be in the directory where the executables are located).
1. Type gdisk64.exe 0:
2. Type p
3. Type q
C:\Windows\system32>gdisk64.exe 0:
'gdisk64.exe' is not recognized as an internal or external command,
operable program or batch file.

When installing Windows i believe i removed the mac drive, is it possible to undo that and install OSX the same way as i installed windows and then start over with bootcamp to get windows 10 again? Just doing it correctly this time...

You will need to go to the directory where the program is located. In my case it was in Downloads.

GPT Fdisk will provide much richer information. It may also be possible to fix it from the Windows side.
Ok, now i got this!
C:\Users\Ulrik\Downloads\gdisk-windows-1.0.0>gdisk64.exe 0:
GPT fdisk (gdisk) version 1.0.0
Problem opening \\.\physicaldrive0 for reading!
1. Do you have a second Mac?
2. Can you install OS X on an external disk, if the answer to 1 is no?
1. Yes.
2. In progress
