No bootable disk after a failed attempt to merge partitions.

Hi,

I apologise if I've posted this in the wrong place, I've not posted here before.

I tried merging unallocated space on my computer with my C:/ Drive using Aomei Partition Assistant, and it required a reboot to do it, and upon reboot it began doing the process and around 95%, it popped up with a notification saying it couldn't progress, and that I could press any key to restart. Upon restarting, it says there is no bootable Disk and I can't press any of the standard buttons to get into bios or startup disk, it just goes straight to "Cannot find a bootable disk, please inset disk and press any button to continue" Not word for word, just writing that based on memory. I have an iMac with Bootcamp (Windows 7), so the Mac build would be intact but I cannot access that because I'm not getting the opportunity to, hoping to recover my C: drive, any suggestions?

Thank you,

~Adam

EDIT

Update, I held the alt/option key, and I'm now in the Mac build. Inside Disk Utility, it's showing Bootcamp as greyed out and unmounted. I'm not sure what to do to correct this.

Decided to back up my data through Finder, then use Bootcamp Assistant to get rid of Bootcamp, then make it again and restore my files. Longer method but the only one I could find that worked.
