OSX No Longer Default Boot - Have To Boot With "Option" Key
I tried to dual boot my Macbook Pro Retina 15" (running Mavericks 10.9.5) with Windows 8.1 Pro using mac's "Boot Camp Assistant".
Everything went fine until I entered the Windows Set-Up and then had to cancel it (because I can't find my Product Key). Thats fine, I was just trying out the dual-boot feature - I don't care if I cannot get Windows to work.
PROBLEM: Now, every time I restart my computer, I have to do it while holding the Option key, or else I get the message: No bootable device -- insert boot disk and press any key
When I hold the Option key, I only have the option to boot into the regular Mac OSX, so Im not sure why it is not booting into by default.
I re-partitioned my HD to not have the Windows partition on it at all, and when I go back into Boot Camp Assistant I do not have the option to "remove Windows partition", but I still have to hold the Option key when I turn on my Mac to actually boot into my OSX.
Basically, how do I make OSX my default boot like it was before (as it is the only one on the HD)?
Thanks!
Yea, that's the disk that you are supposed to select as startup disk as it contains files that boots your OS X
recovery partition usually has the word RECOVERY labeled on the recovery partition along OS X it's usually labelled
something like 'OSX RECOVERY'
Good Luck Mate!

My iphone is no longer working I have black screen with a picture of the itunes logo and a USB cable. When I try to connect my iphone to itunes the device is not detected, can anyone help me? I desperatley need my phone back
I have had a 3GS for 2+ years. After upgrading to IOS 4 (now 4.3.5) I began having problems. In the past week, my screen went to the itunes logo and USB cable twice -- unprovoked -- just found it sitting there like that! I connected to itunes and it did restore from a backup but it is a major inconvenience. I am also searching for answers, but better back-up regularly!

Hi, I'm using MAC OSX 10.6.8 and have intermittent issues with receiving new emails - sending is OK. I've tried the workarounds (take offline & take online), quitting mail etc - no luck. Have cleared space, checked Window - Doctor and server has green light. Mail Activity shows 47 emails waiting to download, iPad and iPhone download them all OK - no extra big files stopping the download either. In the past, quitting mail has worked, but not today... Any suggestions?

I did force shutdown on my MacBook Pro (2006 year, 15.4"), so, when I tried to boot, it shows apple logo (as usual) and shuts down. When I booting MacBook with Option key pressed it shows lock icon and field for password. Please help me.
Wait for advice on repairing a damaged filesystem. Forceshutdown stops processs in mid-stream and leaves some parts not-valid.
Do not proceed until you get that avice. -
Updated to Tiger, stuck on grey screen BUT boots fine with option key
I've searched the forum and found many other similar threads. But no real answers for my particular problem. Here it is. iMac 800 MHz G4, 512 RAM was on 10.3.9. Updated to 10.4.5. Then booted from a firewire hard drive and fixed permissions and ran Disk Warrior. Now when I try to boot up normally it just stays on a blank grey screen. No Apple logo. No spinning wheel, nothing. Weird thing is it boots up fine if I hold down the option key at start up and select the hard drive. So, I've done that and repaired permissions and run disk utility. Says everything is OK. Even zapped the PRAM. But still, only way to get it to boot is by holding option key and choosing hard drive. Any ideas?
Hi Steve, What other start up options are you seeing when you boot with the 'Option' key? Have you tried a 'Safe Boot"? Hold down the 'Shift' key while restarting until (hopefully) you see the spinning gear wheel. Wait while it restarts, this takes a lot longer. If you can boot into 'Safe mode' then in System Preferences>System>Start up disk, make sure that your hard drive is selected.
If you can't boot into 'Safe mode' (you should be able to) then when you have booted with the 'Option' key, follow the 'System Preferences' advice above. Select your hard drive & 'Restart'.
Also have a look at
Dr Smoke's Troubleshooting Startup and Login Items.
For future reference, bookmark his X-Lab home page. There is a wealth of helpful information. Obviously he'd like you buy his 'Troubleshooting' e-Book, but there's loads there for free.
As Dr Smoke would say: "Good luck! "
Have fun too!

No screen displayed when booting with options key held down
When I hold the option key down to select which OS I want to boot into I am getting nothing displayed on the screen but the booting has paused waiting for my input because I can use the cursor keys and return to get the system to boot.
Anyone got any ideas as to why I cant see the choices?
Thanks
GaryJust a quick follow up on this problem. I have just tried the Mac Mini on my TV using the HDMI port and I get the boot menu displayed when holding down the Option Key and it works fine. The issues are arising when I plug a VGA adaptor into the mini display port and use that with my monitor. The monitor is not reporting any out of range or sync signals while booting and I have tried 3 different monitors of various ages and all have the same result.
I also get no apple logo or any display while OSX is loading when I use the monitor

Mac Pro only booting with option key down
I have an 8-core mac pro that is great except for some odd booting issues. I have 3 internal drives, one with OSX 10.4.9 on it, the other with just files and the last with windows XP. I also, at times, have USB drives (or an iPod) plugged into the mac. When I restart, even if I have selected a boot volume in the startup settings, the machine will just go black. Sometimes it will play the startup chime multiple times, other times only once or not at all. The only way to get it to boot up into osx or windows is to hold down options. Even then, it only seems to work if I unplug all external drives from the machine. Any ideas whats going on or how I might fix this?
Thanks!If you remove all of your USB/FireWire devices will your start up issue go away. What about resetting PRAM…

My primary boot disk is encrypted as is a secondary boot disk (backup) but I cannot boot using any other disk. System 10.8.5, MacPro 4.1.
All disks mount using primary boot disk. All disks check out as OK and I have repaired permissions.
When I choose in the control panel the Mac boots but will always use my original boot disk.
When I select the disk using the option key at startup, the boot process stalls with a grey screen and a spinning cursor.
Thanks,
DaveStill trying to figure this out. I erased the drive, did a format using disk util and then re-installed the system but I still cannot get the disk used as a startup drive. I also tried an external firewire drive and it won't allow me to boot from it either.
I can choose it starting up with the option key but it just gives me a blue screen and the spinning cursor.
If I select it in the startup pref pane it boots into my other startup drive only.

Boot camp stuck during installation option key not working
Hi, its my first time posting in the forum. I was trying to install windows 7 on my 2011 imac, everything went flawlessly until the first windows setup restart. First of all there is a blac screen showing every time a restart to install the windowa goes on. I thought it might have been a bad installation and tried to boot into mac os but the option key is not showing anything and it imediately starts booting from the windows cd. Now I am stuck not able to boot into any of the OSs. Is there a way to boot to Mac OS without using the option key? Or what should I do?
Welcome to Apple Support Communities
You have to press the Option (Alt) key after hearing the startup chime. If you do it before, the iMac won't detect the Bluetooth keyboard and it will start directly to your DVD. Try this -
System Preferences Startup Disk Vs. Boot with Option key depressed.
External FW drive connected via standard 400 FW cable, is recognized by System Preferences>Startup Disk, proving that it contains a valid OS X system. But when selected, and clicking Restart, first in the System Preferences>Startup Disk window, then in the modal dialogue, the computer beeps, but does not restart. Same behavior when the computer's internal drive is selected.
The only way to select a startup disk is booting the computer (select Restart from Apple Menu) holding the Option key, clicking the required icon, and then clicking the arrow at the right end of the window.
I have run DiskWarrior, zapped the PRAM (that should take care of startup settings), no change.
Sum up: System Preferences>Startup Disk does not perform.
Powerbook PPC.Charly,
there might be a timing problem. At the time when the Mac PRAM asks for the startup disk the firewire disk might not be "present" yet. Can you turn on the external disk manually?
Does the preference pane "remember" your selection of the startup disk or does it change it back to the internal disk?
You might want to run some system maintenance, especially clean the caches: Mac OS X 10.3/10.4: System maintenance

Booting from a external drive with Option key?
I have made a clone of my MBP's drive via Carbon Copy Cloner.
Now I can boot from USB 2.0 extra drive selecting previousely the startup disk in MBP preferences.
My hard disk has some problems and I want to have an emergency bootup so I have some questions about this:
1-Restart the computer and hold down the Option key until disks icons appear on screen, does't work. It appears only HD (HFS+ journaled) icon and not LaCie USB drive (HFS+) icon why? Any solution?
2-HD with a few bad blocks and volume structure error (other hardware tests passed) can be repaired with reformating and reinstaling OS X?
3-Do I have to format the disk with Disk Utility erase and "zero out data" security options and reinstal OS X from my OS X Installer Disc?
Thanks for the helpYes I have a LaCie USB and Firewire external drive.
I can boot from USB or Firewire if I select the drive previousely with startup preferences.
The problem is, when restarting with USB (or firewire) external drive, I can see only the HD icon when hold down the alt key of my MBP.
In your case have you two icons at the startup? Your firewire drive is HFS+ journaled formated ? Is this relevant? -
Bootcamp volume selectable in Startup Disk but won't boot. Bootcamp not visible with Option Key
My bootcamp volume is selectable in Startup Disk System Preference, but Windows 7 will not boot stating no bootable volume. The Bootcamp volume does not appear when option key held down during startup. Windows 7 booted fine before I booted into MacOS. When I tried to reboot in Windows 7, that's when I received the non-bootable error. All looks fine on the Windows 7 volume.
I'm working with a Macbook Pro Early 2008, 256 GB SSD, Windows 7 and the Boot Camp Support Software 4.0.4033.
I tried to re-install Windows 7 on its 32 GB partition, however Windows reported volume is not in proper format???
I tried repairing my Windows 7 volume with my install disk, but apparentl after having to update my initial Windows 7 instalation (disk bought in 2009) about 3 or 4 times, my Windows 7 install disk reports it cannot repair the now updated version of Windows 7 on my hard drive. Lovely. Brilliant engineering.
I looked into editing my partition table, but that process appears more a hack/bandaid for the underlying problem that more than likely still exists.
Any suggestions, other than painfully starting from the beginning???
Thanks.Well, want to rule out drive case,, as those do come up with EVERY new OS, just hit Lion 10.7 forum when it came out, or when 10.6.0 came out 3 yrs ago.
Maybe the power adapter is the weak link.
As I said, and goes back yrs, not a fan of FW/USB/eSATA case from major vendors (LaCie, WD, Seagate etc).
And you could try another case. Be sure to buy a case that lets you swap in your own hard drives though.

Windows drive no longer available at power up with Option key?
I've done a byte to byte copy of a separate disk drive (320GB) that was my Vista x64 bootcamp drive. (In a MacPro) to a new 750GB drive. After I completed the copy process, I pulled out the 320GB drive and put in the 750GB drive. I hold down the "Option" key during power on and expected to see both my Mac drive and my Windows drive boot option. Unfortunately I only see the Mac now.
If I go into OSX I can see my Bootcamp drive on my desktop (Untitled), can open it and see that all my windows files are there. So what am I missing to get my bootcamp drive to show up during the power on Option process?
Thanks, Rob.RAID is destination for dmg image file.
But tried it again using a single Mac HD boot drive just to eliminate that possibility. Got the same error:

Removed Parallels and BootCamp ... now have to hold the Option key to reboot.
Ran Parallels and Windows XP in Boot Camp for over a year. No problems. Pretty well filled up the hard drive. Uninstalled Parallels and wiped out the Windows Partition. Since then, when I boot, I get a message that says it's looking for a boot device (probably a windows message) and I have to hold down the Option Key to see the Mac HD. Everything else appears to be working fine.
I'm suspicious it's a Master Boot Record (or whatever the Apple equivalent is) but I don't know how to fix it.
It's not pathological ... just mildly irritating ... since you don't have to reboot a Mac very often:))).Thanks so much. I was looking for something much more complex, I guess:)). Have a great day and thanks for the help!!

I have no "open with" option for downloads
I click on a file within a website to open it, but the pop up box does not have the "open with.." option, only the save option. The file type is a text document with the extension ".prg" which is associated in my Windows Folder Options to open with Wordpad. Within Firefox Tools/Options/Applications, this file type does not show up, so I cannot change it. I read elsewhere where this is blamed on MIME type in the HTML header, but Microsoft Internet Explorer gets it right every time, only Firefox does not recognize the file type.
As an aside, the same site has files with the extension".chg" that I open with Notepad. Firefox gives the "open with" option for these files, with Notepad as the defauld, but the "Always open with" is greyed out. Not that I care, as the default is what I want, but....Firefox goes by the mimetype and not the file type as IE does.
