Hi guys, After I recently messed with the windows partition and deleted it manually. But now I lost control over my Mac Partition too. Now I cannot boot or repair the partition in any ways. When I try to fix it, I get the notification "Disk Utility can't repair this disk, Backup as many of your files as possible, reformat the disk and restore your back-up files". I have tried different methods mut look like the apps cant touch the partition or something like that. I somehow managed to install windows again, and can reach my files from it. They are in good shape and I can back-up now. But since I don't have much time, I am looking ways to repair the MacOs Partition and get back to work asap. I believe there is something wrong with the MBR or something, because Disk Utility does not allow me to change anything and says it uses Master Boot Record. Any ideas? Thanks.
