IMac saying no bootable device in startup
Please someone help me!!
Ok, so I wanted windows 7 for my iMac so I created a bootcamp partition and installed windows 7 on my iMac. Everything was running smooth than today booting my mac it showed me (no bootable device insert boot disk and press any key)
Also I tried the alt opinion key and it didn't work, I don't know if it's my keyboard because yesterday I spilled a little bit of chocolate on it, and from yesterday my keyboard was acting strange.
So please someone help, I feel as if it's the keyboard but I don't know for sure. Help
Then you need to do this:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This may help but if not then you will need to erase the OS X volume then reinstall as below:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Computer saying no bootable device on startup
Computer saying no bootable device on startup
Try holding down the Option key while booting.
Hopefully you'll see the Startup Manager window where you can select the startup disk then click Restart. -
When I turn on my iMac, it shows a black screen and says 'No bootable device - enter boot cd and press any key'.
I'm not sure what to do, I did not recieve a cd with my mac to boot it up (I ordered it online).
Also I can't find my harware serial number (I've tried many times to input what I thought it may be from my receipt). I saw that I need this number to contact apple support, my 90 day complimentary support is still valid so I wish to contact them.
I don't know much about apple products as this is my first apple computer so any information is helpful.Hold down the Alt/Option-key at startup of your iMac to get the Boot Selection screen.
From that choose to boot into OSX.
Once in OSX go to System Preferences then Startup Volume and reset your OSX to be the default.
The new iMacs have OSX 10.7 Lion preinstalled and don't come with any CD/DVD anymore.
Instead OSX Lion includes a new feature called "Lion Recovery".

I'm getting this message again. When I restart using the option key everything is ok. When the computer goes to sleep it has the above message. Is there a setting I need to turn off so this doesn't happen all the time? Thanks.

Hi,
How do i quit bootcamp when it say
"No bootable device -- insert boot disk and press any key"
cuz i resraart my imac and the nextday i went to use my imac i just say mi that.
Can you please help mi out ?Reboot holding down the Option key between the tone and the apple logo w/pinwheel. When the boot manager gives you a selection of boot partitions, choose your Lion partition. Once booted, go to System Preferences > Startup Disk > select your Lion partition.

Hi Lexie,
Try these steps
When the grey screen appears when you first switch on the mac, hold down the alt key straight away until a hard drive icon pops up. If this doesnt work step 2
Insert the mac install dvd into your mac when the mac is on, dont worry it can be on the grey screen. Then restart the mac with this disk in the drive and as soon as the grey screen pops up hold the "C" key, this will boot from the disk drive. After a period of time a menu should pop up asking to install mac, but dont worry about this. Just goto the menu bar at the top and find startup disk. Once you are in there select the Machintosh HD or which ever your drive is called, then select restart. This just resets the startup disk. If this fails step 3
When you turn the mac on hold Command+Option+P+R before the grey screen appears and hold this until the mac restarts and gives you 3 beeps. Then let go and it should work This command just resets the PRAM and NVRAM which is just a small part of memory that holds simple information such as the startup disk.
All of these steps will not make you reinstall anything or damage any of your data.
Good luck! -
What happened at the Apple store that caused my computer to do this.
It passed the diagnostic check with flying colors. So I got the green light from the Genius to purchase the MacBook Pro.
Got home.
Pushed power.
Screen says:
No bootable device-- insert boot disk and press any key...
What happened? He said it would be like a new MacBook Pro when I got home and turned it on. This isnt like that at all.
Someone please advise me what to do? The Apple store is closed now. :-(It's trying to boot from a Boot Camp volume that doesn't have a working installation of Windows. Restart and hold down the option key until you see one or more disk icons. Select the one representing your Mac OS boot volume and press return. When the boot is complete, open System Preferences > Startup Disk and set the Mac OS volume as the default boot device.

Hi
When your system starts press F2 at BIOS prompt and do a hard drive Diagnostics test to see if your hard drive has failed , You may get a failed short DST test which will Indicate hard drive failure . Is your machine under the 12 month warranty ??

HP laptop says "no bootable device" for weeks at a time and then fixes itself
Hello,
I am a college student. I have an HP pavillion laptop that I boughtin 2009- I do not currently know the exact product name because the IT center of my school has it. It crashed in 2010 and was found to have come with a faulty hard drive, and the hard drive was replaced. Ever since then, once in a while it will get a blue screen (the same blue screen I got the first time it crashed) and then whenever I try to turn the computer on it says "No Bootable Device." It will give me this error message for days or weeks at a time, and then all of a sudden it will start working again without having lost any information.
I have brought it to the IT center at my school twice. The first time they gave it back and said there was nothing wrong with it. This time, I was very insistent that there was something wrong and explained the problem in detail. I got a call today and they told me that they ran tests on the hard drive, and it's working fine, and they cant do anything else. They also said they could try reformatting it if I bring in the discs that it came with, but my dad told me that means I will lose everything on my hard drive.
I'm hoping there will be a simple solution that I can do whenever I get this error message but I'm guessing there won't be. I apologize in advance because I really don't know much about computers so I may have trouble understanding computer jargon..
Thanks!Without knowing the product involved it is hard to help. You are correct there is likely no magic bullet if you are getting "no bootable device" other than shutting it down and trying to boot again. A 2009 laptop is now 4 years old and that is about the expected life of a laptop although this one seems to have been snakebit from the start.
Ask the IT Center exactly how they tested the hard drive. I am suspecting you have one of the ill-fated dv6000 or dv9000 series models which have heat related issues and high failure rates, but won't know until you provide the model number. -

Shared disk (Tried 2 methods BootCamp and Disk Utility) to install windows, but the section is not shown, to be precise, when you turn the Mac while holding Alt key shows the partition for system restore and disk partition with OSX, and not created by me. If you try through Bootcamp that actually says "No bootable device". What could it be? I have a macbook pro 371ll/a, OSX 10.9.5 . Thanks for the reply.
Thank you! All established, but a new problem with Windows 7 partition. If you install Windows on a Mac, say you gave 30GB on widows, after installation you have 2GB from 30GB, while the size of the files in Windows is 18 GB, should be free 12 from 30. Hidden files on large amounts of no (100 MB all hidden files together). Know that there is a disk which reserves memory for the system, but I don't have, I look through the taskbar there is a disk with osx and bootcamp and all. What could it be, if you of course know.

After install it just says "No bootable device found" [SOLVED]
I have been trying (several times now) to install Arch Linux. After the install, it just showed the message "No bootable device found".
I have already asked for a solution here, but until now no one could really help me.
I will paste my text from the other site here, to explain exactly my situation:
I've been trying to install Arch Linux. After the installation, it shows the BIOS screen and after that there just comes a message that says "No bootable device found".
I have retried the whole scenario now some times, still it just shows the same message...
At installing, I have followed the Unofficial Beginner's Guide from the ArchLinux wiki.
Here is what I did:
First of all, I wiped the hard drive (on which before the wipe was Windows Vista installed) and put GPT on it by using gdisk. Then I set up some partitions, which now look as the following (output of parted):
Model: ATA ST9160310AS (scsi)
Disk /dev/sda: 160GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB BIOS boot partition bios_grub
2 2097kB 107MB 105MB ext2 Linux filesystem
3 107MB 21.6GB 21.5GB ext4 Linux filesystem
4 21.6GB 30.2GB 8590MB linux-swap(v1) Linux swap
5 30.2GB 160GB 130GB ext4 Linux filesystem
Then I mounted the root partition (sda2) to /mnt, after that also the boot and the home partition (sda3 and sda5) to /mnt/boot and /mnt/home and at the end formatted and activated the swap partition (sda4).
Now I began installing the base system. After selecting the mirrors, I installed base and base-devel.
At the end of the install I generated an fstab.
Then I finally chrooted into /mnt, set up some Locales, set a root password and then installed and configured Grub2, exactly as it is explained here.
At the end I exited from the chroot environment, unmounted the partitions and rebooted. You know the rest... It just showed the message that it coudn't find any bootable devices.
By the way, I tried to install it on this computer.
Hopefully someone finds out what I did wrong, thanks in advance!

Why does it say No bootable device Insert bootable device?
Why does it say No bootable device Insert bootable device?
Can i suggest you spend more time explaining the situation, what you are doing, what has been done recently, etc? One sketchy line is not much help.
That said, i will guess that yu are trying to turn on your mac, and it gve you that message, immediately.
It means that soemthing has caused it to not recognize your hard disk and the OSX software on it. It could be:
1. a dmaaged disk
2. corrupted software
3. a firmware bug
4. a hardware failure
Most likely the software has been corrupted at least slightly.
The best first step is to boot from your original CD and run disk diagnostics/ repairs on the hard drive.
I hope that fixes it.
Then go buy an external bootabl hard drive and begin making complete, bootable backups on weekly basis.
