Couldn't read partition map
Hi,
I tried to install Windows 10 on my computer but the setup failed. So I deleted the partition in Windows Setup again, accidentally some other small partition with 200mb. It seems I have screwed up the partition map.
How can I restore it and claim back my original disk space? Luckily, OSX boots perfectly fine, but I cannot delete the partition in disk utility, not even in recovery mode. I get said error:
