"D" key at boot?

If you hold the "D" key at boot, shouldn't it load the "Apple hardware test"???
When I hold "D" at boot, I am stuck at a blue screen (no apple logo yet) and nothing happens until I let go of the "D" key. After 2 to 3 minutes of holding "D" nothing has loaded or changed and I am stuck at the blue screen. I let go of the key, and after about 20 seconds, then I get the Apple logo, and then the spinning wheel. The computer then boots normally.
By holding "D" at boot, shouldn't I be taken to a different screen or something so I can run the hardware test?
Any ideas?

HOWEVER, why do I need to insert the disk? I was told that on all Intel computers, the AHT is "built into" the computer - no need for a disk. Also, on my mothers iMac, you can hold down "D" with no disk in, and it boots to the AHT just fine?
I would guess that you have wiped / reformatted your drive at some stage and done a fresh " install" from a retail OS DVD Scott.
If this is the case then the necessary /System/Library/CoreServices/.diagnostics stuff won't be present on the drive and the EFI loader won't be able to call on it unless you have the correct DVD in your optical drive.
Another possibility, if you haven't ever erased your drive and installed from a retail OS DVD, may be that you have some underlying directory corruption, or that the relevant files in coreServices have themselves become corrupted.

Hi LamboMong,
just try this:
http://refit.sourceforge.net
install, reboot twice and choose the Windows-Partition on next startup.
(The apple-bootloader doesn't display all bootable harddisks.
With rEFIt you can boot from all partitions/harddisks on your computer.)
I hope that will solve your problem.

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up.

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up normally. Why do these key fonctions no longer work?

It could be your timing if on a bluetooth keyboard. I find it best to hit the keys as soon as i hear the chime, release and hit them again but this time holding them before the chime ends....like a fake pump in football.
But....you can always open up system preferences, startup disk, and select your bootable clone for booting. If it doesn't show up there, the Mac doesn't think it's bootable.

Hey rudreshchoubey,
Thanks for the question. The following resource may help to resolve your issue:
Boot Camp Installation & Setup Guide
http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf
If Windows doesn’t install properly
Verify that you’re using an original, full version of the 64-bit version of Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, Windows 8, or Windows 8 Pro.
Restart your Mac and hold down the Option key until one or more disk icons appear on your screen. Insert the Windows installation disc into the optical drive or insert the USB flash drive with Windows into a USB port on your Mac. Select the Windows installation disk icon, then click the arrow beneath it. Quickly press any key on your keyboard to start the installer. Follow the onscreen instructions to repair or reinstall Windows.
Thanks,
Matt M.

Press any key to boot from cd

Every time I start my computer it will automatically go to a black screen saying press any key to boot from cd. When I hit a key nothing happnes. If I start the computer and hit the option key and then select MAC the computer will start. I think this is a boot camp problem because this problem started when I tried to install a windows 7 64 bit (my computer only supports 32 bit) on my computer through boot camp. I now have a fully licensed windows 7 and I'm trying to install it but when I start the computer and press option and hit the windows 7 start up disk nothing will happen.

Kyle,
Sounds as though a do-over is in order. But first, you'll have to make OS X the default in the boot menu.
To return to Mac OS X and make it the default:
Hold the Option key at startup, to bring up the boot menu.
Hold the Control key. The straight selection arrow will change to a wrap-around arrow, indicating a "persistent boot"
While holding this key, click your OS X volume,
Let go of the Control key
Mac OS X will now be the default.
Start the Boot Camp Assistant, restore the original volume, restart, and try again. Read the Installation and Setup Guide carefully this time through. If you have further problems, post your experience in a new topic, as it is likely your issues will be somewhat different.

Have to press keys upon boot

I have to press keys upon booting on some steps so that the booting process would go further (the same with shutdown). If I don't press some keys, the process will just stay there.
It doesn't help to switch between kdb/mouse and evdev drivers. I don't understand this thing.

Ok, I'll try to explain a bit better . When booting Arch we of course get the nice log of what's going on (as defined in rc.sysinit) but in some steps the proces just... stops. And no matter how crazy it sounds, when I press some keys like 2 or 3 times, the booting process... continues! The same thing happens upon shutdown. We waited like (my dad's PC) 20 seconds and nothing happened until we hit some keys a few times. It was friggin' embarassing and hilarious at the same time when the task was to change from unstable Ubuntu to stable Arch.

Cool, will check this out as soon as possible. It will be the next saturday if my dad is willing to try the move of Ubuntu -> Arch again .

Can't complete windows installation - Stuck at Press any key to boot from..

I am unable to install windows xp service pack 3 or windows 7 on to my iMac running latest boot camp installer. I can start the installation process, but when windows installer completes copying all the files on to the boot camp partition and reboots the system I get stuck at this message "PRESS ANY KEY TO BOOT FROM A CD OR DVD", which won't go away even if I wait for 10-15 minutes. To get rid of this I have to hard reset the iMac by pressing the power button for a few seconds and then boot into Mac HD using the option key.
Please advise if I need to tweak some settings to complete the installation or if you need more information to resolve this issue. Thanks!

I was able to complete the installation process by formatting the windows bootcamp partition through windows installer (and not using Mac disk utility to format the partition into NTFS format). Hope this helps someone.

Option Key for Boot Camp not working with New iMac Keyboard

Hi, I own a early 2006 Intel iMac. Recently, my wife complained that the keyboard was getting dirty. Basically I think she liked the new keyboard on the new Aluminum iMac better. We purchased it back in August and everything worked great. Oh I also had the beta version of Boot Camp installed. Everything worked great, hold Option down on boot and could choose which OS to go into.
Fast forward to now, purchased Leopard and love it! Decided to wipe the system and do a fresh install. Everything is installed (Leopard, Boot Camp, Windows XP) and working great, that is except when I press and hold the Option key at start up. If I have the new keyboard installed, the Option key does not bring up the boot manager. However if I plug the original keyboard in and hold Option, it works!!!
Ok I could see a problem if the new keyboard was NOT an Apple product. But it is and frustraiting as I can use the control panel to choose. This is a long round about method and does not make a happy wife with me. HELP!
Jhan Jensen

Thanks for the info! I was about to call myself and I may still do so. I am hoping if Apple gets enough of these calls then maybe it will spur them on to get it done sooner. (Apple are you listening) I will do the same with the KB swapping, she will be happy at least she can still use the new keyboard. She types a lot and has be really happy with the new keyboard and its response.
Thanks again for the help!!!

G3 will not recognize Keyboard C key on boot

I have 1999 G3 with 128M Ram running OS9X. I wanted to upgrade to OSX 2.4 and reformatted 12G drive to 2 partions, 8G and 4G. I did not read install notes and started install OSX on 8G partion and went away for a while. When I returned, had just gray screen with no keyboard or mouse response. Rebooted with processor reset key and now have gray screen with blinking folder question mark. After reading discussions, tried various key combos and nothing is recognized except Pram reset. Cannot boot from CD as C key not recognized. Now what?

We're obviously not dealing with an installation issue, but with a hardware issue. Whatever the issue may be I feel confident that it was not caused by the installation of Jaguar to an 8 GB partition. So, I believe that we can rule that out for the moment.
It may well be that we are dealing with a faulty keyboard, although that is by no means certain. However, it is the easiest part of the hardware to troubleshoot by simply trying a different keyboard. The OP reports that the keyboard is unresponsive and only resetting the PRAM worked. However, since that works, one wonders why other keyboard commands don't. In any case, it would be easiest to try a different keyboard, if one were available.
The 12 GB internal HDD to which the OP is attempting installation is the original HDD which came with the computer over 10 years ago. It may well be that the HDD has outlived it's useful life. This is a more likely scenario than a faulty keyboard since we know that these drives have an average life of about 5 years. The OP reports that during or after the installation operation something happened so that when the OP returned to the computer
just gray screen with no keyboard or mouse response. Rebooted with processor reset key and now have gray screen with blinking folder question mark.
This has the appearance of a failed installation. Note that the keyboard could not have caused a failed installation since the keyboard was instrumental in getting the installation started and would not have had an active role in the installation process after that. Nor could the installation have caused the keyboard to fail, as far as I can figure. The internal HDD might have, though. Thus, my first inclination would be to replace the internal HDD and try the installation again.
Of course, there may be other hardware issues that prevent booting, or makes the keyboard seem unresponsive. I do not have a B/W, nor am I familiar with the hardware to venture a guess. However, I have seen a number of topics that suggest that there might be peculiarities about the hardware. Besides, the hardware is old enough that it may have components acting up. Thus my suggestion to post in a forum where users who are familiar with the hardware and may have seen similar issues have an opportunity to consider and comment on the issue.

USB key and Boot

Hi guys,
I have bought a usb key of 500Mb to carry some data with me when I need, but I should want to use it as a boot key when necessary. Do you know if it is possible and how I can do it?
Thanks
Pad

I have forgotten, but does K8N DIamond support USB start up flash drive?
In my bios I don't find anything about it (Version1.9) do I have to realize that it is not supported?
Thank
Pad
P.s.
reading many web pages on the google search I have noticed that procedure is quite long, but at this time if anyone have any floppy disk how can boot or to access to his pc when it is broken?

Invalid Keys Response (Boot Camp)

Hi,
I run Boot Camp (Windows 7 Ultimate) on iMac and have no issue with the keyboard thus far but notice that the at-key ("@") is inter-changed with another key and backward-slash key ("\") is now hex-key ("#") and I can't find it and trying out all the keys.
I went back to Mac and run boot camp to download the latest driver, went back to Windows and did a repair but the result is the same.
What I notice is :
#     -     become "pound sign"
@     -     become " (double quotes)
\     -     become #
|     -     become ~
"     -      become @
Tried trobleshooting on the regional and language settings but it does not help either.

Tried the BC update (v2.1). Still exactly the same. No volume keys, no eject key. no brightness keys, no nothing!
Plus Windows says my iSight is unprogrammed and detects IR receiver at every boot, but fails to install drivers for it. Whatta bummer.

Swapped drive with SSD, now have to use option key to boot

I recently replaced my HD in my Macbook Pro with an SSD. I used SuperDuper to create an image to an external USB drive that I had. I then removed the stock HD from the Macbook Pro, replaced it with the SSD, booted with the Lion install disc and went into disk utility, created a partition (Journaled, guid) and restored my SuperDuper image to it. Now, every time I reboot my MBP, it sits at the gray screen (no apple logo) for quite a while, then finally the apple will pop up and it will boot, although quite slowly. If I hold down the option key when I reboot, the option comes up right away for the SSD, I click it and it's very fast to boot. Once in the OS, the speed is awesome and no problems. I also used Onyx to check the startup volume, repair permissions, etc and everything went off without a hitch. No errors and according to that my startup volume is OK. Also updated to the latest 10.7.2 patch and that went fine too, although I had to use the option key on reboot.
Does anyone know what I could investigate that could be causing this boot issue. I'd like it to boot directly into the OS quickly without the option key. Is there somewhere that I have to specify a new primary boot device or something?

Go into sys preferences then startup disk and check highlight the SSD and select Reboot.
You also need to enable TRIM support.

P35 platinum(7345) and "F" keys on boot up

does any body know of any f keys to press on boot up apart from f8 -- f11--and f4 in bios. i only need for my help section when trying to resolve problems for my self and others. thanks in advace

Oh man, do I feel your pain. In the last 2 weeks, I've had to re-install Snow Leopard 4 times because of a machine lockup. I haven't been able to find anything to fix the problem. I have 2.5 GB of RAM installed, over 70% of my hard drive is available (free GB to use for virtual memory, scratch disk, etc.), and just basic applications installed. Just as you said, I'll be doing something extremely simple, such as browsing the web (maybe 2 tabs open), and transferring files from my Time Machine backup in the background; out of nowhere, that **** beachball will start spinning, and things grind to a halt. Maybe 5-30 seconds later, everything resumes as normal. It's getting so f'n bothersome. I've read everywhere: it's Safari, it's the network, it's Time Machine, it's this or that. I've literally tried everything, and nothing seems to fix the problem. SMART status reports no problems with my disk, Disk Warrior says my directories are optimized, iStat Menus say the CPU isn't working too hard, nor am I running out of memory. For God's sake, what is wrong?!?! I'm sorry if I'm ranting, but I've just about had it. Currently, I'm using Chrome (even though I miss Safari), I'm not backing up to my Time Capsule, and I only open one app at a time (and remember, my installation is brand new; I've simply installed the COMBO updater via Software Update). It still "hiccups." I really, really, really hate to say this, but it's true: I never had problems like this with my old HP running XP. I absolutely love the Mac, and up until now, I've been an overzealous fan boy, but I can't keep doing this. I'm a web developer, so I need my computer to be running in tip-top shape at all times. Oh well, if you figure anything out, I'd love to hear about it. Good luck to you. Again, sorry about the diatribe. Have a good day.
