If you can't start up from macOS Recovery

So i decided to go back to OSX lion and realize that i cant find the boot menu. I have two windows computer and a linux elementary Loki available to help. Any assistance will be of great help to me. If you formatted the disk for linux, the recovery drive will not be there any longer without reinstalling through a Mac boot drive. I solved the problem.. Hi Tried this but was unable to finish. Tried many times. Im sure I missing something really simple. Is this the location it refers to. If you downloaded it from the App Store then it will be located in the Applications folder.

Thanks a lot! This worked like a charm. Followed the procedure as described and the problem is all fixed now. Thanks again.

Louis — In your case just make a USB boot disk. You can do this with the Terminal and a copy of the OSX installer app. Thanks fro confirming for me. Saves me time of trying and possible problems. I followed everything but in terminal, I am unable to write where it says password! If you are trying to enter password into terminal from sudo or elsewhere and it is not showing up, type it anyway and hit return. Unless you deleted it accidentally or cloned the drive, the Recovery partition is almost certainly ok. It is invisible by default and hard to access by any regular user. I would recommend backing up your Mac before doing this since it modifies the partition table.

Then run it on your boot disk. Worked for me, but I also have done the reinstall method. Bought used. It came without a recovery partition though I have a bootable clone kept up to date just in case. Will the process and tool to create a recovery partition without totally reinstalling OS X work on this configuration?

I formatted and restored a drive from a Time Machine backup recently and Recovery partition did not get restored in the process. I ended up running the Mac OS X installer again, which updated to the latest version of software plus rebuilt the Recovery drive.

Worked great, no problems since. Name required. Mail will not be published required. All Rights Reserved. Reproduction without explicit permission is prohibited.

Since Disk Utility can no longer access the hidden Recovery HD partition, we have to use a different method, specifically, Terminal and the command line version of Disk Utility, diskutil. Our first step is to create a disk image of the hidden Recovery HD. The disk image does two things for us; it creates a copy of the hidden Recovery HD volume, and it makes it visible, easily accessible from Mac's desktop. We need to find the disk identifier for the hidden Recovery HD partition. Enter the following at the Terminal prompt:. Terminal will display a list of all partitions your Mac is able to access, including those that are hidden.

The line with the Recovery HD item will also have a field labeled Identifier. Here you'll find the actual name used by the system to access the partition. It will likely read something like:. The identifier for your Recovery HD partition may be different, but it will include the word "disk", a number, the letter "s", and another number. Once you know the identifier for the Recovery HD, we can proceed to make the visible disk image. The next step is to partition the drive that you wish to have the Recovery HD volume created on.

However, since the size can change with each new version of the operating system, we suggest making the partition size larger than 1.

The next-to-last step is to clone the Recovery HD disk image to the partition you just created. You can do this in the Disk Utility app using the Restore command. If you remember back to when we started this process, we asked you to use Terminal's "diskutil" to find the Recovery HD volume. So, our last task is to set the Type. This will also cause the Recovery HD volume to become hidden. We need to discover the disk identifier for the Recovery HD volume you just created.
