No bootable device, trying to bootcamp. HELP!

I want to install bootcamp on my Macbook Pro. It's a late 2011 13 inch. I have mountain lion. I followed instructions to make the option for making a version install disk on a usb stick from an iso image of windows 7. Well, the bootcamp process seemed to be working fine until it got to the point where it automatically restarted to install windows and a black screen with white text came up that said "No bootable device - insert boot disk and press any key" although my usb with the boot disk was in my computer and it wouldn't let me press any key.
Also, Important. I know how to use the option key and get back to my OSX hard drive. That is not the issue. the issue is that I can't seem to make my usb bootable. Or something like that. I'm not the most tech savvy person ever, fyi.
When I go into disk utility and go to info on my usb which I made into a windows partition thing using boot camp, it says Bootable: No. I'm assuming it needs to be YES in order to boot from it... how do I make it bootable? Shouldn't it have done that in boot camp assistant?
I hope that made sense. I have tried with multiple usbs. Nothing seems to work. I tried pvram reset, someone suggested that. Didn't work. repaired disks, etc.
Please help, I am at a loss and very frustrated!

I followed instructions to make it so that it would work, at least it worked with other people who had an internal dvd drive.
I guess I'll try to burn the iso onto a dvd, I didn't know that would work. Not sure how to do it though..

Macs don't show me created the partition for windows. And if through Bootcamp that says "No bootable device found" . Please HELP.

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.

No Bootable Device Found- Need Some Help

Hello,
I'm hoping that someone can help me with an issue. I've looked at several of the discussions on here but can't seem to find an answer to my situation. I'm trying to install Windows 7 onto a Mac computer at work (OSX operating system version 10.8.4). First thing I did was download the Windows 7 file to the computer and it showed up as an ISO file (we do not have a hard copy of the disk or an internal optical drive). Next, I attached a 16GB USB, opened Bootcamp and clicked on the Create a Windows 7 install disk, Download the latest Windows support software, and Install by partitioning. The files become located on the USB, the partitioning takes place, the computer restarts, and then I get the "No bootable device- Insert Boot Disk and press any key" message. When holding option at the restart, I can see the Mac HD, recovery and USB icons, but the Windows Installer does not show up
I've tried to remove the Windows 7 using Bootcamp, re-partition the Mac and re-create the Windows 7 install disk with no success. I have also tried attaching an external CD/DVD drive, using Disk Utility to burn the ISO files to a CD and using that as the install disk with no luck. I'm a new Mac user so I tried to include as much information as I could in this. If anyone has any help or suggestions as to how to help get the installer to show up, it would be greatly appreciated!
Thanks

Bootcamp - No bootable device -- insert boot disk and press any key help plz

Hello there!
I recently upgraded my imac mid 2010 system with a SSD hard-drive. The old "main" drive went to the place of super-drive and after reinstalling OS X into the new drive and wiping the old drive a very interesting problem happened. I started trying to install windows 7 via bootcamp. I did everything what the bootcamp assistant says and after the imac restarts itself it just says No bootable device -- insert boot disk and press any key. Firstly I thought that maybe something is wrong with the installation disk (i have an external super-drive connected to the imac). After restarting the imac once again i held down the option button and arrived to the screen, where it shows the avlaible boot options (different disks). Now, what I saw, was funny. The bootcamp assistant had'nt created the bootcamp drive at all. Atleast it did not show it. After doing this two-three times the result was the same. My next idea was that maybe, there is an issue with the concrete SSD model I am using. So I went back to OS X and opened the bootcamp assistant and restored the state of the OS X SSD drive. Next I did an bootcamp partition onto the old drive I have installed. But the result is still the same. Now my head is empty of ideas.
Has anybody had a similar problem and can you please give me tutorial what I did wrong or what to try next?
Thanks.
Indrek.

Hi Michael!
Yep, I did get this running. Not in a normal way (meaning the easy way). What I did, is that I just created the BOOTCAMP partition in OS X. Just let it format and create the partition where you would install BOOTCAMP.
After that I discovered that via a ISO program (WinClone) you can directly restore a previously created OS X boot image to your current computer. So, I installed a blank Windows 7 to my macbook pro, didint install any drivers and just let it work up then. Then I went back to os X (in macbook pro) and made a bootimage for the BOOTCAMP partition. After that I saved it to my external harddrive and wired it to my iMac. In iMac I just downloaded the same boot-image program and restored the bootimage that I made in Macbook Pro to iMac. After that I made an restart and the bootcamp section with windows worked well with my iMac. Install the bootcamp soft and you can do everything and everything works. FYI, you get the windows working via those steps, BUT if you either delete or do anything to make your bootcamp partition unworkable then you will have to repeat those steps again. But it´s fast non-the-less, so it shouldn´t be a problem for you.
If you didin´t understand anything or something doesen´t add up, send me a letter or a notification.
Hope this helps.

No Bootable Device Error when trying to bootcamp!

Hey guys I have been trying to bootcamp on and off for the past month or so now. Anyway I downloaded a windows 7 x32 bit iso from Microsoft's website. I then used Burn to burn it to a disc by doing: Copy> Dragging the image in> Mount and then right clicking on the image on the desktop and clicking burn to disc. Not bootcamp itself worked fine, a bit slow, but i managed to make a 100gb partition. Now whenever I try to boot into windows, I get the dreadfull "No bootable device - insert a bootable device and press any key"
I know the .iso is valid because i succesfully made a Parallels V<M with it, but parallels is too slow for skyrim.
I think its also important to note that I have using an external optical drive, since my dad got gum in it XD.
Anyways help is VERY MUCH appreciated! If you need anymore info, just ask.

Okay so I found a similar tutorial, only a little more detailed. This can be found here: http://www.andrewsavory.com/blog/2011/2156
So I follow the instructions to a tee, but when I try to start the installation of the VM, I get a "Missing Operating System" Error.
Anyways Heres what I did:
Went to terminal and typed this in:
mkdir Virtual\ Machines
/Applications/VMware\ Fusion.app/Contents/Library/vmware-rawdiskCreator print /dev/disk0
Then This:
/Applications/VMware\ Fusion.app/Contents/Library/vmware-rawdiskCreator create /dev/disk0 3 windows7 ide
SO I enter those right in terminal as is and hit enter. Then I search using spotlight and found two files:
windows7-pt.vmdk and windows7.vmdk
So I follow the instructiopns again and I think I might be messing up at this step:
" You’ll then be taken to the Customize Settings screen, where you want to configure the ISO to boot from. Click on the CD/DVD (IDE) option [...]
And then select the location of your Windows 7 ISO:"
SO I choose my windows 7 x32 iso FIle and just close the window. Am I missing anything?

Can't find a bootable device after trying to install Windows 7 in bootcamp

I've been trying to install Windows 7, 64 bit. Haven't managed yet due to problem that I've just posted about in a separate thread. Now, though, when I switch on it says 'can't find a bootable device'. If I switch on whilst holding down the Option key, the (OSx) internal hard drive is there and I can boot up. But I don't want to have to do that every time... Tried resetting the PRAM as advised, made no difference.

Look at Apple () -->system preferences -->*Startup Disk*
hope this helps

10.9.2 install Bootcamp win7 64bit iMac mid 2010 no bootable device - external superdrive, USB Stick

Hey all,
big problem here.
Trying to install Bootcamp on my iMac 27" mid 2010.
The thing is, during the installation, i get the "no bootable device" black screen, and i think i know why... but i need help.
System, a mid 2010 imac, 2TB HD ( Original) and an SSD Samsung 1TB at the Optical Drive SATA connection.
2TB HD is empty atm. OSX Installed on the SSD.
Bootcamp Assistant. Problem nr. 1.
He first did not want to let me create an USB drive. after hacking the assistat, deleting the "Pre" thing in the info.plist, that worked so far.
https://discussions.apple.com/thread/5479879?start=105&tstart=0 and several other postings got me so far.
Then when using the assistant, after choosing partition and so, when the iMac restarts, i get the "no bootable device" notice.
Read a lot, and it seems, that older iMacs, that originaly came with an internal superdrive only can install win 7 from that internal superdrive.
I have the problem, that i had it removed to put the SSD there.
So, when doing an EFI Boot, choosing the win USB Stick or the Win in my External Superdrive, - "no bootable...."
So i searched more. rEFIt should help. Installed, and all, doesnt work, same thing. As soon as i want to boot Win from the CD or Thumpdrive, doesnt work. :-(
In one of the many posts, someone wrote something about starting Shell in rEFIt first, etc... didnt work as well.
then i found this post:
http://www.andrewsavory.com/blog/2011/2156
sounded promissing. Somehow getting win installation files onto the Created Bootcamp partion with Virtual Mashine. But it didnt work for me.
The VW Fusion ware is different, and non of the steps he discribes works.
So how can i get it working.. it seems like it is somehow blocked to access something from the USB Ports.
Logicaly i would have to get the installation files onto a Internal drive. i Tried to create a partition and copy the Win 7 USB Thump using Disk Util Progeam onto a seperate, internal partition.. but he just does not what to do that... errormessages when trying to copy it, recreate the drive, etc.
So, i do have a 2TB internal HD, which i can use, an external superdrive, USB.Sticks. any gameplan?
And for Error-excluding: i have an original Win 7 64 bit CD, a burnd one and controled the Hash of the loaded ISO, which i downloaded for the USB-Stick.
Any help? pls!!!

Hi Sam, the Mini Optical may draw too much USB power.
Can you restore that .iso to the Flash Drive as a CD/DVD instead of an image file?

Why is Bootcamp is not working right on my MacBook Pro (No Bootable Device)?

      I am not a computer geek but I learned a lot through reading forums and other people’s experiences. I want to use Windows 64bit in order to work on an Architecture portfolio using AutoCAD, Revit, 3DS Max, Sketchup, Photoshop, and Illustrator. I use these programs at school and on a PC and love it. I want to use these programs at home but wasn’t confortable with the Mac version so I had Windows installed on Parallels but even after upgrading my RAM to 10GB my computer was quite slow so I rather work on my projects separate from my Mac side (also, would feel less distracted) and set up Windows on Bootcamp, but I’ve encountered some issues.
        I wasn’t planning on partitioning my hard drive until after updating to Mavericks. Then I noticed I did not have the option to create a Windows 7 install disk so I reprogrammed the info.plist for the option to appear. After following all three steps, the computer restarted with a black screen that read “No bootable device – insert boot disk and press any key”
-Pressing any key didn’t help so I restarted and held the alt/option key until the booting options popped up and only got
     -Macintosh HD
     -Recovery HD
-Did not get a Bootcamp boot option so I repartitioned the hard drive to a single volume and repeated several times and still the same thing
-I tried using Disk Utility to partition, but the results were the same
-I tried using a different Windows7.iso file and still the same
-I also tried a 2.0 and 3.0 USB thumb drive for the .iso file
-Bootcamp Partition shows up on my Finder window on the side tab under ‘Devices’ and shows up on Disk Utility, but not on Startup Disk and not when I start my computer and hold alt/option.
-I did not plug in the Windows Support Software at all (I read somewhere that said not to plug in until after Windows partition boots and installs, but didn’t even get to that point)
-Had no CD nor USB plugged in other than the flash drive that carried the .iso
-I read a comment that said to copy the files bootcamp made (WINISNSTALL) to the ‘root’ of the flash drive, but that I see they are already on the ‘root’ (unless I don’t know what root is?)
-I also tried reformatting the partition on Disk Utility from MS-DOS (FAT) to Windows FT Filesystem but fails every time
-I also made a backup, and restored the computer (took hours!) and repeated everything
-After trying almost everything, I still get the “No bootable device – insert boot disk and press any key” message.
When it gets to reformatting, I have no idea what I am doing, the only reason I am trying all these methods is because of what I read on other peoples success stories and comments, but its either my computer does not work, I am missing something, or I’m not geek enough.
-Just to let you know, the first .iso I had worked on Parallels but not for Bootcamp
-I don’t think this matters but I am trying to partition my 320GB hard drive at 70GB for the Windows side. The only thing I will be installing would be the architecture programs while my projects and files would be saved on an external hard drive.
-Computer is up to date at version 10.9.1
-MacBook is from Early 2011, 13-incher
-The only method I could think of that I did not try was using a DVD to create an .iso disk because most comments said USB gave the best results.
-Should I use my Hitachi 250GB External Hard Drive 2.0 instead of a USB Sandisk 16GB 3.0 and Verbatim 4GB 2.0
PLEASE HELP ME ANY ADVICE WOULD HELP!! And Happy Holidays!

Your post is incredibly hard to read, font is way to small.
If you used Boot Camp Assistant to create a partition to install Windows to you need a REAL Windows 7 or 8 install media and license key and you have to actually install Windows on your Mac. Boot camp is only for creating a partition to install Windows and starting the Windows install from REAL Windows install media.
That Windows install media has to be a DVD disc, if your Mac has a built in DVD drive (Apple does not allow Windows to be install any other way on Mac computers that originally come with a built in DVD drive), or from a USB stick with the actual Windows install files on it (Not an ISO of the Windows install files).
So the question is did you install Windows on your Mac? It doesn't look like it from the Option key boot and the list of available Boot Devices you posted.

Bootcamp "no bootable device" Option key not working

Ok recently rebuilt 2 older "Intel Core Duo" Mac Mini's with SSD drives. They work great and have been flying, however on one of them I wanted to setup BootCamp so that I could run Win7 Pro on it as well.
So here is what I did...
- When I first built the Mini's I used a bootable Firewire drive with Snow Leopard installed
- I had the drive divided into 2 partitions at first
- when I tried to install BootCamp error message kept telling me it needed only one part, so I finally made Primary OSX part one big part, then I was able to get BootCamp going
- I choose "I have Mac OSX Install disc" because "Download the Windows support software" would not work
- Next it created the BOOTCAMP part and told me to put Win OS disk in drive
- I put in an OEM Win 7 CD I borrowed from work, so I could see how it worked.
- When it rebooted, it Did not recognize CD and all screen said was choose Option 1 or 2, (neither option had any text, and the keyboard would not take any input)
- Tried numerous times to get back to OSX, used every boot option I could find online but none would work.. Also Mini would not give back CD for nothing
- Next I opened up Mini to get to CD, I had a friend that was able to get one out by opening up the actual dvd drive but I was trying to avoid that. So what I ended up doing was using a putty knife to keep CD from spinning on bootup. After about 10 to 15 seconds of the CD not spinning, it finally kicked it out for me. (YAY!!)
- New problem, now I have the "No Bootable Device - - Insert Boot Disk And Press Any Key"
- I have tried the following. Removing the drive and plugging in a Sata to USB cable so I can access it from other Mini
- I thought that if I deleted the BOOTCAMP part it would allow me to boot back to OSX, I tried renaming Part to what it was before, I have tried putting in a Formatted drive with no OS on it, I have tried installing the contents of a Win 7 OEM CD onto Formatted drive as a single FAT part.
Nothing Works, I am either stuck at the "No Bootable Device" screen, or if I turn on Firewire drive with Snow Leopard I get a blinking cursor that never shows any text.
At this point, I don't want BootCamp on that Mini anymore, I just want my working OSX, but I cant get anything to work and I'm afraid to stick a CD in the Mini for fear it wont give it back to me and I end up damaging it getting it out. I even created a CD with rEFIt on it, but after I formatted a totally different drive and the Mini is still expecting to finish what it start with BootCamp, it leads me to believe that there is some BIOS or data stored somewhere that is not on the harddrive. If so, could I pull the RAM, or push some sort of master Reset button some where?
I'm also thinking that I need a non mac USB keyboard, perhaps maybe there or know Aluminum Keyboard drives in the memory where the Mini is trying to finish the BootCamp install.
As a side note, I sure wish Apple would have designed the Mini to fail Safe not fail broken.
Please Help.
Randy

The Formatted test drive did not have Any OS on it. I just thought that since that was how I installed it originally, that it would work.
I put in SSD straight out of package, connected Firewire drive with SnowLeopard install, and it booted to it and asked me for to install to which drive, I choose SSD and it took off..
So what your saying is, do the same thing but hang SSD from broken Mini onto working Mini and boot up with same Firewire drive, and have it install OS back onto Broken SSD drive.
Assuming all of this works correctly, why would plugging it back into broken Mini work? Wont the Broken Mini still be looking for BootCamp to finish what it started? (just seems that way from what I've experienced so far)

Help with "No bootable Device -- Insert boot disk and press any key" problem

Alright, I am on an Early 2011 17inch macbook pro. I have removed the superdrive to install a secondary disk drive for mass storage, then replaced the original one with an SSD blah blah blah. I do everything from the books, run bootcamp, make my USB windows 7 bootable in Bootcamp, go through everything and allocate 65gb towards windows. I have tried 4 different USB sticks and 3 different ISOs. Every time I try it, I get the same "No bootable device -- insert boot disk and press any key". I then have to hold down the power button, then restart, hold down option/alt key, and boot regularly into mac. I also read that holding option/alt whilst starting the macbook pro will show the windows USB stick, well it never appears. I dont know what I need to do, what I am doing wrong, but nothing is working. I guess the last thing I have to try is buying a superdrive and burning ISO to disc then try that. But I dont want to go out and spend more money. Other people have gotten it to work just fine from USB, I dont know what I must do or what I am doing wrong...
Open to suggestions and in desperate need of help. Anything is appreciated.
Thanks!

How to install Bootcamp on a 2009 Macbook Pro that does not have a disc drive

"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.
Since Bootcamp can only be installed on the HDD I believe disk1 is the interesting one. Here is the output of sudo gpt -r -vv show disk1:

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).

No bootable device installing w7 w/ Bootcamp and external DVD reader

Hello¡ Good night!
Lets see if anyone can help me find a solution since google, youtube and forums cant. (Wanted to call the apple support, but since my mac is from 2010, they want me to pay 19 S)
I have a MBP 17 inch from mid 2010, with MC OS X 10.6.4.
I installed Windows 7 like 2 or 3 years ago.
Everything was working fine, didnt give a single problem. Installed it easy by doing the partition and then with the original copy of Windows 7 32 bits did it quite easy and fast. (with bootcamp)
I used Windows and mac for all this years.
Last week, I decided I wanted to format my windows partition (since it was full of trash).
I had with me my original copy of windows and the installation of mac drivers (the same cd I used to set the drivers after the first intallation. Its the original, came with the mac).
I deleted the partition from the windows on the Boot Camp assistant, and re did it. And then the nightmare started.
After I prepared the partition from the bootcamp assistant (its the 3.0.1) I select the install windows now. Then the cd dvd from my Mac Book Pro started running but after a while it shut down, pulled out my windows cd and a message on screen saying , insert an original copy of windows and click yes... .. After trying for a while I decided to put in another cd, which was doing the same. Discovery, the cd,dvd from my MBP was broken. I checked up online to see if there was a problem and I discovered that this was not something new. A lot of people was having troubles with their optical drive stopped working out of nowhere and the only solution was changing it. Thing I cant do right now, since just that costs 120 euros...
I readed in some forums that you can use an external CD DVD reader so I bought one for 20 euros (Samsung SE 208A) which works perfectly fine in all the computers, even the MC OS X reads it and I can use it perfectly.
I put my original copy from windows 7 on the CD DVD, and click start windows installation in the Boot Camp Assistant. Which just reboots the computer perfectly.
And when the windows installation is supposed to start I get a message
No Bootable device... Please insert bootable device and press any key.
I tried all the solutions I saw online, nothing worked.
Pressing Option key while startup only opens the MacintoshHD
Pressing Option key with MAC OS X installation CD and then changing it to windows. (Windows cd appears on the bootable device, I select windows and I get back to the same back screen . No bootable device)
Pressing C and selecting Windows (From the CD DVD) and restart.

Thanks for the answer, but I dont have the windows anymore...
._. I have been reading a lot of forums (which is being hard, since everyone seems to have problems and not answers).
We managed to downdload a tool called rEFIT and we are now being abled to select the windows cd, but it's giving still problems. (Changing the list data from boot camp allows it to detect other boot routes) <- starting to feel like a hacker...
But we are still stucked.
We are trying to update my Boot camp to 3.1 (that seems to solve that problem) but for now it's being impossible, everything in the apple download website are .exe, which are the drivers ONCE you have windows INSTALLED. Clicking to Upgrade Software doesn't upgrade it.. So I'm looking into it...
I'll keep you guys informed if we manage to solve it.
Thanks for your time!
