IMac9,1 Fusion Drive - booting in recovery mode

Hi,
after installing a Fusion Drive on my iMac early 2009 3.06Ghz with ML 10.8.2, i'm not able to boot into recovery mode by hold cmd+R.
The temporary solution is press cmd+R just after resetting the NVRAM with cmd+option+P+R.
This operation must be repeated each time i want to go into the recovery.
I don't know if this is a bug of my iMac.

Yes, i made a "Fusion Drive" by joining my SSD 256GB + HHD 1TB. I follows one of some guides presents on the web. The system works well apart that i'm not able to reboot in recovery mode on startup with cmd+R.
At the end the "Fusion Drive" is only two core storage volume fused togheter nothing of new.
For the new mac mini this software technology is already available to the public and my fusion drive works like mac mini's "Fusion Drive" (read this: http://arstechnica.com/apple/2012/11/fusion-drive-quick-look-our-predictions-con firmed/)

My MacBook won't boot into recovery mode after new hard drive installation. Please help!

I just installed a new hard drive. On boot it keeps on going to the flashing folder with a question mark inside.
I was able to format the new hard drive but am unable to boot into recovery mode to install the operating system over the air.
When I hold down Command -R it keeps on taking me to the flashing folder.
Please help!

A new hard drive doesn't have a recovery partition. It's totally blank.You're going to need either your original install discs or a Snow Leopard retail disc from which partition, format and install OS X.

How do I boot into recovery mode with wireless keyboard

I am unable to boot into recovery mode using either cmd-R or holding down the alt key. How is it supposed to work?
Message was edited by: Niklas Brunberg (better title)

I understand your concerns - I'm glad both of my machines are dual bootable (just in case) and I have my Snow Leopard install disks..... However, this is what Apple has decided, so we need to find the best way to deal with it. Personally, I've tested the recovery mode several times and, at least on my machine, it was not reliable (i.e. it wouldn't work - I tried it again and it did, but it spent more than an hour downloading the entire 4 GB installer again and then another 30 minutes installing it), and on a third try, I found that it had vanished because I had cloned by drive. When you clone, only your system is cloned, not the extra partition.
So, I've decided to rely on a) my bootable clones and b) a copy of the installer (.dmg) in case my clones fail. I don't feel comfortable relying on something that requires an internet connection and a full download to work. But, that works for me; you may want to take a different approach.

IMac will not boot in recovery mode

I have tried to boot into recovery mode (CMD-R) in Mavericks. I tried with my hard drive and a Mac Install disk. Disk utility has grayed out the erase option except for unused space. Can't partition either. I am attempting to donate to my church. They will use their Apple ID to load their current OSX. Help

If you still have the Install OS X Mavericks.app file from the App Store or can download it again, you can recreate your Mavericks Recovery HD using the Recovery Partition Creator 3.7 utility and the Install OS X Mavericks.app.

Broken screen, erased main disk, cannot boot to Recovery Mode to reinstall OS X

I am using a MacBook Air from around 2010, not really sure what version of the OS was on it prior to erasing. The screen is broken so I have to either duplicate the screen or use clamshell mode to see anything. When booting in Recovery Mode by holding Command + R, the only option is to use clamshell mode with an external monitor because otherwise only a gray screen is shown.
My issue is a result of erasing the main disk while in Recovery Mode and then shutting down the MacBook. I turned the computer back on assuming I could use clamshell and Recovery Mode to reinstall the OS but unfortunately this isn't working and I can't get anything to display on the external monitor.
I cannot use Target Disk Mode from another Mac because there is no FireWire port and there is also no Ethernet port.
This leads me to these questions in trying to figure out how to reinstall OS X:
- Is it not possible to boot in Recovery Mode after erasing the main disk?
- Is it not possible to use clamshell mode after erasing the main disk?
I have also tried booting while holding Command + Option + R to use Internet Recovery or booting while holding just Option, there was still nothing to be displayed on the external monitor after closing the lid to switch to clamshell mode.
I'm stuck, any suggestions would be greatly appreciated.
MacBook Air, Mac OS X (10.4.8)

FYI:
I have tried booting into Single User Mode, using fsck to repair permissions, but to no avail. However in the Single User Mode I did notice something unusual. When trying to reboot using the command 'exit', a long list of errors came out.
Most were Library/Extensions/... .kext is not authentic; omitting from prelinked kernel.
Some errors were ...: No such file or directory
And afterwards the errors were stuck there and no reboot occurred. I also couldn't type anything.

Mountain Lion only boots into Recovery mode after using iCould lock

Hi everyone!
I have searched the forums for hours now, but I can't seen to find an answer to my question, so I'd like to ask it.
Recently my system partition failed due to frequent kernel panics caused by a cable in the screen I think. The kernel panics still occur, but I don't know what to do with them.
I managed to save my files and reinstall my osx, which is Snow Leopard (the disc came with the computer). Then I wanted to install my purchased copy of Lion through Appstore, but it said it's no longer available in my country and I couldn't download it again.
Then I decided to buy a copy of Mountain Lion which I tried to install. I managed to do it, and I tried to explore my new operation system.
I tried the iCloud app as well, including the Lock. It locked the computer, and rebooted, but ever since I couldn't unlock it.
When it asks for the password I enter it and it accepts it, but doesn't unlock, only lets me into Recovery mode. Now I reinstalled the whole thing over again and when the Mountain Lion install finishes, it only boots into the Recovery HD without asking.
So if I reboot my computer, no matter what I do it only boots into Recovery Mode.
Please help!!
Mike

I was afraid the Apple Store wasn't going to be an option.
Based on your previous post, I was under the impression you could download Mountain Lion, but when you installed it, it locked up again. Not true?
I don't know how to remove it. You can try contacting Apple support through the link below to see if they can help you get this unlocked.

Are the kernal panics new since all this happened?
Here is some information about kernal panics.
Kernel Panics - About
Kernel Panics - Avoiding and Eliminating
Kernel Panics FAQ
Kernel Panics FAQ (2)
Kernel Panics - Understanding and Debugging
The articles discuss where kernal panic reports are filed. After you have a kernal panic, copy the report and post it here. Please copy and paste rather than using a screen shot. There are several people who can read them and they can suggest what to do next. Reading kernal panic reports isn't something I've totally figured out yet.

MacBook Pro OSX 10.9- Cannot boot into recovery mode or use USB bootdisk

Hi guys,
I'm having an issue with my MacBook Pro running OSX 10.9. I want to re-install the operating system, however the computer freezes when being booted into recovery mode or when rebooting into a USB boot disk. Either the spinner freezes or it moves to a screen with just the Apple logo.
Thanks in advance

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

Mac keeps booting into Recovery mode

HI,
my macbook pro mid 2009 keeps booting into recovery mode,
if I select primary disk in recovery mode or at boot holding shift it quickly showes crossed out circle instead of an apple at boot screen than boots into recovery mode again.
I have repair permessions, repaired disk (no errors) and reset pram but no luck.
Is there anything alse I can try?
Thank you.

Looks like some files might be damaged. You will likely have to reinstall the operating system. I hope you have a back up of your data.

HT4718 Are there alternate ways to boot in recovery mode?

The original problem: 2007 era Macbook Pro display goes bad.
Solution: We bought a new macbook pro. It was time for an upgrade.
The opportunity: We decided to connect the old pro to an external display and use it in clamshell mode and set it up for the kids to use.
I attempted to delete my wife's user account, yet the machine still shows 88 gigs used when clearly the two new users I set up (one administrator) are not using so much. I thought if I could reinstall OSX that my problems would be solved. Not only am I not worried about losing data in a reinstall - I want to.
The current problem: I cannot boot this mac into recovery mode while it is in Clamshell.
I am using a wireless apple keypoard, but can really only boot up using the restart option as the power button is closed up in the clamshelled laptop. But when I do that it appears to me that the wireless keyboard is not connecting in time for the recovery mode to catch.
I thought the simple solution would be to open up the old beast and use the actual power button. Good news is that when I do this, it must boot into recover mode. Bad news is that evidently recovery mode does not allow mirroring of the display. So I cannot actually see my recovery mode. My external display is simply a secondary display - greyed out, and all I can do is wave the cursor back and forth.
So: Are there any alternate ways to boot into recovery mode?

Have you followed these instructions?

OS X Lion 10.8.2 won't boot into recovery mode

Help! OS X Lion 10.8.2 won't boot into recovery mode, I get a grey screen, the apple icon and the spinning symbol...Does anyone have any suggestions?
Have a MacBook Pro (2009) and had no problems until upgrading to LIon from Snow Leopard... thanks!

Hi there - thanks very much for your suggestion, it did reboot eventually but took a long time to get there.
I've have run Disk Utility. After Verifying the disk it said it needed Repairing - so tried doing that and got the message " Error: Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files" I have got Time Machine but haven't backed-up since Dec 12...Can I use "Restore" to copy the MBP HD to an external HD and then re-install Lion?

Retina iMac 3tb Fusion drive Boot Camp failure

Trying to install Windows 8.1 to a 1tb Bootcamp partition on 3tb Fusion drive. BCA creates the partition, Windows installer sees it, but requires formatting it, but then it can't install to it. I get an error that it can't create or see the partition. I'm assuming this has to do with BCA creating the partition someplace Windows can't handle it (past the first 2.2tb of the drive).
Here is the info requested in a previous thread.

Booting into recovery mode and Web service in 10.7 server

I have two servers: Server A is running 10.6 server and server B is running 10.7 server. Both are on the same LAN at a data center. My questions are as follows:
1 - is there a way to restart server B into recovery mode remotely? (and not using a KVM)
2 - if server B was booted successfully into recovery mode is there a way to screen share with it from server A? If so how would this be done?
3 - can Apple Remote Desktop reboot a 10.7 machine into recovery mode and still continue to see its screen?
4 - in the Server app of 10.7 server there is a default website setup in the Web service. it doesn't seem possible to edit any of the information for this default website, is this true?
5 - is there any way to get the Web service in the 10.7 Server Admin tools? it is missing among many other services.
Thanks

Probability is very high that you have a hardware failure. You should get an external bootable drive (or startup with a bootable DVD if you can) JUST to prove that it's not the motherboard, but probably the hard drive that's failed.

Booting in Recovery mode After Update

I have an Early 2013 MacbookPro Retina with Maverick and I was having issues connecting to my Wireless Router so I decided to Reboot the laptop.
After it rebooted, the Mac logo on the Grey Screen showed up with a progress bar. The progress bar took a while to complete and then computer shutted down.
I then pressed the power button to turn it back on and it started in recovery mode. Using the DiskUtility I see the disk, I see the Partition but cannot mount it. I ran the DiskUtility's Verify and it tells me to Repair the Disk. I click Repair the Disk and it tells me the disk could not be repaired and I should to backup the maximum number of files possible and then format and reinstall the OS. But for the sake of God, it cannot even mount the partition! How am I suppose to backup anything?
I'm so ****** off, I lost a week of work. Spent the week working away of the office and the Time Machine Backup is a week old.
*** Apple!
Please someone tell me that there is something I can do to recover my work!

Here's what I'd try:
Hook up an external drive. Boot to the Recovery partition. Partition and format the external drive, then install OS X on it. When that's done, boot while holding down the Option key and choose the external drive. From there, see if you can now read the internal drive and get your files off. Once you have what you need, you can reformat the internal.

Cannot boot into Recovery Mode but need to reinstall OS X, any suggestions?

My Mac boot is stuck at the Apple logo with a progress bar, and even when booting Recovery Mode (Command+R) it is stuck. Hence I don't think I can use Internet Recovery to reinstall OS X. Do you guys have any suggestions as to what to do? Thanks!

FYI:
I have tried booting into Single User Mode, using fsck to repair permissions, but to no avail. However in the Single User Mode I did notice something unusual. When trying to reboot using the command 'exit', a long list of errors came out.
Most were Library/Extensions/... .kext is not authentic; omitting from prelinked kernel.
Some errors were ...: No such file or directory
And afterwards the errors were stuck there and no reboot occurred. I also couldn't type anything.

Macbook only boots into recovery mode

Any help on this issue would be greatly appreciated. The other day I was watching a movie on Quicktime and out of nowhere the computer froze up. I waited a minute and then finally just did a force shut down of the computer. I then started it back up but instead of coming to the login screen, it started up in recovery mode, where I get the OS X Utilities window.
I opened disk utility where instead of the normal Macintosh HD listed on the sidebar, it says "disk0s2". I tried repairing the disk and it came up with an error saying it couldn't be repaired and I have to reformat the disk. I took it in to the genius bar and they ran a battery of tests on the hardware and it all came back fine, so he told me it must be a software corruption issue.
Now I could just reformat the disk, but being the idiot that I am, I haven't done a Time Machine backup in several months, so there's files I would really like to recover before going through with the reformat. The guy at the genius bar seemed to think it wasn't recoverable, even by a data recovery company, but he said there's always a chance. Is there a chance? And is there anything else I can try to do at home? I've heard good things about Disk Warrior, but how would I run it if I can't even get to my desktop? From another computer?
I have a 2013 Macbook Pro, retina display, 256GB SSD, 8GB memory, running Mavericks.

I was afraid the Apple Store wasn't going to be an option.
Based on your previous post, I was under the impression you could download Mountain Lion, but when you installed it, it locked up again. Not true?
I don't know how to remove it. You can try contacting Apple support through the link below to see if they can help you get this unlocked.
