After failed repartition, No bootable device on startup

Hi,Got a really annoying problem.
I had a windows partition using bootcamp. I then tryed to remove it using bootcamp but got a error message stating that drive could not be repartitioned. I tryed again but the program froze so I force quit it. Now I cant access the windows partition but there is space occupied on the drive where it should be.
Also when I turn the Macbook on it tries to boot into windows I guess because i get a no bootable device message.
I can still access the mac partition by holding down option at boot but this is getting annoying really quickly.
I have tryed repairing and verifying disk permissions and erasing free space but besides having more room on this partition nothing else.
Have tryed tips on other disussions and nothing has worked.
Any help would be amazing thanks.

I received a new iMac on Wednesday, and therein began my problems. I needed to set up a partition with
Bootcamp so I could run Windows 8.1. After repeated efforts I was unsuccessful, and could not get the
the drivers to work. I read on the Apple support discussions that many have also been not able to get
Bootcamp to work.
I gave up and installed Windows 8.1 with Parallels. It was easy, but when I installed the 42 Windows 8.1
updates, I lost Internet Explorer and could not download things from the internet such as virus protection
software. I had to reinstall Windows and decided not to install any updates. I'll take my chances with
malware and only go on the internet via Safari. Windows 8.1 is terrible, and I see on the blogs that many
people have had dissasters after installing the updates.
Ineeded Windows to run my Quickbooks software. In retrospect, I should just have installed
Quickbooks For Mac even though folks say it is not as good as the Windows version. My accountant
would have needed to adjust to the change. Beware of Windows, and stick with Mac !

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.

Reinstalling is not possible, because the installer says that the update is allready installed.
That implies that your new machine has a newer build than the combo update. In that case, boot with the restore disc that came with it and restore that.
The baseline 10.6.2 build is 10C540 and according to http://support.apple.com/kb/HT1159 yours is probably 10C2234.

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.

No boot disk after creating a USB bootable device with Bootcamp Assistant.

Hi people, i was trying to install windows on my Mac Pro 4,1. I had to modify the Info.plist in Bootcamp Assistant to be able to make a bootable usb, after choosing and creating the bootable usb my mac rebooted and after i got into a black screen saying "no bootable device"...i tried Win7 and Win8.1 on 2 different USB sticks without any luck. Any ideas? Thank you!

Disregard this message. I give up.

Windows 8.1: no bootable device--please restart system

I know that there have been several posts like this before, but none that exactly fit my situation.
So I have a satellite c875-S7303 that was running windows 8.1. Today when I went to turn it on I got the message:
Checking media [fail]
then: No bootable device --please restart system
I am able to access the setup utility, and I have tried changing the boot mode from UEFI to CSM with no luck. I also dont feel like it is a physical problem with my HDD or the cables because the make and model of the HDD shows up in the main and boot tabs of the sutup utility.
Of course I didnt make a recovery disk, and there isnt a recovery option (that I'm aware of) anywhere in the setup utility.
I feel like the problem is that the boot files are corrupted somehow but the HDD is otherwise ok. Is it possible to boot windows 8.1 with a generic boot file that I can burn to a CD or put on a USB stick?
Any help would be extremely appreciated

I'm planning to get hard drive usb adapter cables to see if I can get any of my data off of it.
I don't have any ideas better than that.
You may need to take ownership of files and folders, BTW, when you access from another Windows installation.

Message 'No bootable device- Please restart' - Satellite C series

Hi,
Only had my laptop for just over a month and the white on screen arrow would freeze completely just after starting up. Was therefore unable to use any programme or do anything on the computer.
Backed up all of my data then got an IT friend of mine to look at it.
Completely wiped the computer to start afresh and am now only able to get a black screen which says :-
'Checking media'
then after two seconds
'No bootable device - Please restart system'.
Restarted roughly ten times now and the same error message comes up.
When I press any key, the message is repeated.
Thanks

Hi
Please check firstly what device has been chosen to boot the notebook.
Usually the notebook should boot from HDD.
So go to BIOS (F2) and check if HDD has been set as first bootable device.
Furthermore you should check if HDD is recognized at the first BIOS page (size, name).
In case the HDD isnt listed there, the HDD is faulty and cannot be found by BIOS.
This would require HDD replacement and new OS installation.

"No Bootable Device" after failed Boot Camp installation (Windows 8 - 1TB Fusion Drive)

On my new iMac /w a 1TB Fusion Drive, I tried to install Windows 8 (still technically unsupported) using the following method:
http://arstechnica.com/information-technology/2012/11/no-support-no-problem-inst alling-windows-8-on-a-mac-with-boot-camp/
Everything was proceeding just fine; I had Boot Camp copy all of the Windows 8 files (a legitimate, store-bought copy) to a bootable USB drive - a feature only available on new Macs running Boot Camp Assistant that don't come with an internal optical drive - and create a 102 Gb partition on the Fusion Drive. It then rebooted and was proceeding through the Windows 8 setup wizard as should be expected, but it couldn't modify any of the partitions on the Fusion Drive and wouldn't proceed. I accepted defeat and decided I would just wait until Windows 8 is officially supported before trying again.
Now, every time I turn the computer on, I get an error message saying "No Bootable Device...", unless I hold down the Option key and manually select "Macintosh HD" (the only boot device listed). I already removed the primary Windows 8 partition, but it hasn't fixed the issue.
I'm thinking that it's one of the 'hidden' partitions causing it to behave like this, or something wrong with the EFI bootloader, but I don't know how to proceed. Any thoughts on this?

I actually did try this (forgot to mention it), and it didn't fix the problem.
However, I just resolved it on my own, doing what I probably should have tried before anything else: running "Repair Disk" in Disk Utility updated all of the boot preferences as it should have.

Boot Camp "No Bootable Device" after OSX Partition Resize

I have a MacBook Mid/Late 2007. I started out with a 500GB drive that I partitioned 100GB for Windows 8 in Boot Camp (yes, I know only 7 is officially supported, not the point as it worked fine.) I wanted to try Mavericks so I resized my OSX partition down 100GB to make a new 100GB Mavericks partition. After I installed it and played around, I noticed when I booted with the option key, my Boot Camp partition was missing. I thought i was becaus eI had too many partitions, so I deleted Mavericks and resized my main OSX back to where it was when I started. The Boot Camp partition still won't show up when I hold option on boot, but when I run Boot Camp manager on OSX it wants to remove it, so it knows it's there. It also shows up in the startup disks pane, but if I select it and reboot, I get a "No Bootable Device -- insert boot disk and press any key" message. If there a way to bring back Windows?
Here's the kicker: My optical drive DOES NOT work. I installed Windows 7 off DVD long ago before it quit working and the only way I got Windows 8 on was through a downloaded upgrade. I know I should get it fixed, but I don't have the money (and I never use it, and this is 2 that have died on me in this laptop.) My system can't boot anything other than OSX off flash drives or external DVD drives (I tried, and I tried reEFIt, neither worked.) So I need a solution that doens't require a boot CD if at all possible.

I can get to and boot OSX (it's what I'm using now as this is my only laptop), I just can't boot Windows. All my files show up fine on both partitions.
You can't add/remove or alter the partitions if Boot Camp is installed, Windows will cease to boot.
To fix it, erase all paritions except OSX. Start over, 2 partitions only (OSX and Boot Camp)

Winxp is gone when pressing option key at startup, "no bootable device"

Hi everyone,
I'm new to mac and recently bought a MBP.
I did bootcamp and installed windows xp and SP3 at the same time in a small partition, I remember it was 8gb.
I had no problem booting in to xp or mac after the installation, I can even press option and see both OS.
But now I cannot boot to windows, at startup while pressing the option key, I only see mac os and not windows. I also tried rebooting from the startup disk utility, but it has a black screen saying "no bootable disk found." It wants me to insert a bootable disk, so I inserted the window xp disk and has to force restart the laptop. Then it started a process like trying to load the files to reinstall win xp, of course I didn't let it.
Now when I went back to disk utilities I see that the winxp partition is 9.2gb, it was 8gb when I made it.
Recently I split my mac partition into 2, I tried to do the time machine back up, but then it takes too long so I canceled it and deleted the partition. I wonder if this affects my window xp partition.
Now I cannot see winxp when pressing option key at startup, but can see it in startup disk utility, and disk utility. When I boot from startup disk utility, it shows "no bootable device, insert cd, and press anykey..." I tried verifying and repairing the parition in disk utility, didn't work.
So this is all I did before I cannot boot into xp.
1. made new partition for winxp (formated partition as FAT)in bootcamp and installed winxp + sp3. everything was fine.
2. create another partition, and call it "data" <-want to create this for data only, while the other half is for software installation only.
3. create another partition for time machine, but when running time machine it says the partition is too small, so I delete it and make the partition bigger.then I run time machine, but since it takes way too long, I canceled it, and deleted the partition.
4. in winxp, had installed kapersky anti-virus 9.0
Now, I have 3 partitions: 1 for software installation, 1 for data, and 1 for winxp.
So why can't I boot to windows? Did things overwrite? Please help me, I'm so frustrated. Thank you.

Thanks fortuny,
I had read the link you suggested. And since my partition for windows is FAT32, as noted in the website, I can edit the boot.ini directly in my mac. In my mac, it already shows that the partition # is 3,
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(3)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /NOEXECUTE=OPTIN/fastdect
but my window os is not booting.
Like the link noted, "it crashes with the "I'm sorry, we couldn't start up Windows. Do you want to start in Safe Mode?" screen. You'll also see a flicker of the BLUE SCREEN OF DEATH, which flashes an UNMOUNTABLEBOOTVOLUME error so quickly you won't have a chance to read it. This was the hint that the BOOT.INI entries were incorrect..."
According to the boot.ini in the site, my boot.ini file was already set up correctly, so why can't windows startup?
Also something I don't understand from this:
"NOTES: If you didn't follow the instructions and chose to PARTITION the existing volume instead of RESIZING then ADDING a partition, this appears to mess up BootCamp's boot loader and you may have to start again. Step 3, however, may offer you a way out."
When I did the 3rd partition, I did it in Disk Utility in mac, not from the mac os cd, and I split the mac partition into 2, I didn't do the "resizing," then using the unused space to make new partition... I wonder if this is causing the normal booting...
So do I start again by deleting my data partition or start from reinstalling windows? If the problem can be fixed without installing windows, of course, it would be great.

"No bootable device --- insert boot disk and press any key" after setting up Bootcamp

Hi guys,
I am trying to install Windows 7 via Bootcamp but after setting up Bootcamp and restarting the computer I get the error message "No bootable device --- insert boot disk and press any key".
I use an iMac with a DIY Fusion Drive consisting of a 120 GB SSD and a 1 TB HDD.

I have gdisk installed and am ready to mess around. Any help would be greatly appreciated!

So, when I started my iMac yesterday morning it couldn't boot into OS X anymore either. Several hours of restoring later I am back to square one. I tried installing Windows 7 via Bootcamp again but got the same error message. This time I noticed though that Bootcamp asked me to remove the bootable option from the USB drive with the support drivers in order to install from DVD. Does that ring any bells? I am building another USB drive right now, hoping it would ask me again but this I will decline and try to boot from it.
When you restored, was a Time Machine restore used? TM does not backup Bootcamp and does an erase of the partition. It may also erase the entire disk (including the Fusion drive) if the specific backup of the volume layout of the disks indicates a pre-Bootcamp layout.
My MacBook Pro is a 2009 model and also once had a built-in optical drive. I have no idea why it would work on there but not on the iMac.
You also wrote
When I plug the external DVD drive in, the boot manager recognizes a "Windows" disc and an "EFI Boot" disc. If I select the "Windows" disc I get a black screen with a blinking dash.
The blinking dash indicates that it is working, but does not have the requisite drivers to enable the GPU/Mouse/Keyboard on the media being used.
In the MBP case, did you have two drives installed in the MBP, a Fusion configuration, and then were able to successfully install Bootcamp?
For example on a Mac mini I have a DIY Fusion drive, but the sequence was done differently. Bootcamp was installed using a USB stick+Windows 7 ISO.
1. The two disks are not in a CoreStorage set up initially.
2. The second disk is partitioned (64Gb) and a Bootcamp W7 install completed via USB (this is different HW as compared to IMac, because it has no Optical drive).
3. After the HDD is partitioned, the first partition and the SSD are then used to create a CoreStorage volume.
4. Here is the working version and disk layout. (I plan to erase both disks, put W7 on a partition on the SSD, and make the non-Bootcamp+entire HDD in a CoreStorage volume).

I already partitioned my hdd via Bootcamp, supports downloaded, and windows is on an external USB. How can I start installing Windows now? at startup it doesnt show up as bootable device...

hi,
I am having a problem installing windows via bootcamp.
I already partitioned my hdd via Bootcamp, downloaded and copied all the supports for windows, and windows is on an external USB as well. I had to stop the process the other day, so i shut down the computer. Now I am trying to boot from the USB, but I cant get to that point where the computer should restart and windows would start installing.
. After restarting, holding command, it doesnt show up as bootable device.
How shall I move forward? My disk is already partitioned, and if i start the whole process from the beginning, it wants me to partition again - although I already made a 100GB partition for windows.
Please help me out.
best,
Zoltan

So, here is what happened when I tried to make it.(sorry for quality, i had to take them by phone)
At first when I opened it I saw that I could simply resolve it just by stretching the arrow at the bottom, giving the 100 GB back which I partitioned before via Bootcamp. At this point options was not available.
I didnt do it because you mentioned earlier that it might be not designed to install windows.
The second thing I tried I choose 1 Partition from Partition Layout. This time Options were available but I didnt see anything like GPT, the onces that are optionable are on the screenshot.
What do you think how shall I move on? I was thinking to give it a shot with option 1, just stretch it back and try everything from scratch.

HT1199 After trying to install window 7 my new iMac will not reboot back to apple. Black screen "No bootable device -- insert boot disk and press any key". How do I get out of this?

After trying to install Windows 7 in my new iMac It will not boot up back to Apple. I have a black screen with the following "No bootable device -- insert boot disk and press any key". My iMac did not come with a boot disk. What can I do?

Try holding down the option/alt key during a restart and see if you can see/select your boot drive there.

Recovery fail - "No bootable device -- insert boot disk and press any key"

Hello,
I have a problem with Recovery. I don't have recovery dvd/cd so I decided to use recovery partition. After system reboot I press F11 and click on recovery system. After 100% of progress, recovery tells me something like 'now your system will reboot press continue'. And now. After system reboot I see:
No bootable device -- insert boot disk and press any key
I have totally no idea what to do. I read few posts on this forum but I have no Windows 7 CD/DVD and I have no one who can borrow me to install it. I really need my computer back in few hours to work.
Looking for help from You.
My computer: HP Pavilion dv7-6b40ew, Windows 7 Home Premium

Hi,
Assuming this is just a problem with the recovery media, here's an alternative option you could try.
Before trying the following, make sure you can still read the 25 Character Product Activation key on your Windows COA label ( 5 blocks of 5 alpha/numeric sets ).
An example of a COA Label can be seen Here.
You can create an installation disc yourself using another PC - just download the correct Disc Image ( this must be the exact same version that originally came with your notebook ) from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here. These Images are clean and from a well-respected source, however there are only limited versions available.
Windows-7 sp1-iso-official-32-bit-and-64-bit
Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.

Any additional drivers and software you may need can be found Here.
