    sorry when i bother you, but i wanna understand.

     

    after bc create the bootcamp partition it restarts the mac. that failed cause the usb od start windows in efi mode (can see it in the startup manager)

    so after reboot, i hold option/alt and could see at the startup my osx. if i put the windows installation dvd in the usb od, i see windows and windows efi. i click on windows and the drive starts. after a moment i get a black screen with the blinking cursor and nothing happens for a while.

     

    why is the windows installation dvd with option/alt key at startup on my usb optical drive visible? the usb drive from the modified bc info.plist didn't show up in the startup with the option/alt key.

     

    right now i'm really frustated an confused

    The EFI Startup will fail because BCA created a MBR and asked the Installer to start in Legacy (BIOS) mode. EFI mode requires a GPT-only disk. A MBR (or Hybrid MBR) disk needs the Windows non-EFI installer to start.

     

    so after reboot, i hold option/alt and could see at the startup my osx. if i put the windows installation dvd in the usb od, i see windows and windows efi. i click on windows and the drive starts. after a moment i get a black screen with the blinking cursor and nothing happens for a while.

    Once you reboot, you have lost the CSM-BIOS layer that BCA told the Mac firmware to expose. Now you are using the EFI firmware of the Mac. You click on Windows (non-EFI) and there is nothing in the Legacy mode to use anymore. The NVRAM says boot from the internal Optical drive, you are using the external USB OD and end up with a conflict, which cannot be resolved. This leads to a blinking cursor.

     

     

     

     

     

    why is the windows installation dvd with option/alt key at startup on my usb optical drive visible? the usb drive from the modified bc info.plist didn't show up in the startup with the option/alt key.

    Because the Apple firmware/bootmanager recognizes a bootable DVD in the DVD drive. OS X can boot from an external DVD or an internal bootable disk. The USB disk must have a bootable file system. It is not marked bootable by the BCA, because BCA assumes that your internal OD is functional. Plug-in the USB now and use diskutil list to find it and run sudo fdisk /dev/diskN where N points to the USB.

    so, i did what you want. here are the results

     

    sudo fdisk /dev/disk3

    Yosemite installer is not a FAT volume. Your dump shows marked active, but does it have a boot block? You can try Rufus (https://rufus.akeo.ie) to create a bootable USB, which is much better than BCA at these functions.

    I hope this is not redundant but I do not fully understand the steps you helped GMF-Berlin with.  Would you please advise me on a similar situation?

     

    No Bootable Device - SSD Yosemite BootCamp Setup

     

    SYSTEM INFORMATION:

     

    MacBook Pro 8,1 13” Early 2011

    OS X Yosemite Version 10.10.1

    Boot ROM Version MBP81.0047.B27

     

    500GB Toshiba HDD with two partitions:

    1)  Partition formatted as Mac OS Extended (Journaled) running OS X 10.10.1

    2)  BOOTCAMP formatted as NTFS running Win7

     

    250GB Samsung Evo 550 SSD with two partitions:

    1)  Partition formatted as Mac OS Extended (Journaled) running OS X 10.10.1

    2)  BOOTCAMP formatted as MS-DOS (FAT32) hoping to install Win7

     

     

    WHAT I WANT:

     

    I am an engineering student and have to run Windows-based programs for school.  I have used my MBP running BOOTCAMP for over three years on the original HDD and am almost done with school.  I would like to embrace the future and speed up programs both my Mac and Windows partitions by using an SSD.

     

     

    WHAT I HAVE DONE:

     

    — removed optical drive from laptop

    — moved HDD to optical drive location using OWC adapter frame

    — placed new SSD in SATA port

    — formatted SSD as described below and successfully installed Yosemite

      this took a while; had to replace the SATA bus cable cause my new SSD was picky

    — downloaded en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso

    — created bootable USB using multiple flash drives (8GB Lexar; 16 GB Lexar; 16 GB PNY) from above ISO via following methods after formatting the USB to MS-DOS (FAT32):

      1) BootCamp Assistant, with & without checking box 2/3 (Download the latest Windows support software from Apple)

      2) Disk Utility; imaged/restored mounted ISO to USB partition with Master Boot Recored (MBR) scheme (not GUID Partition Table or Apple Partition Map)

      3) Microsoft bootable disk creation software on a PC

    — created BOOTCAMP partition using the following methods:

      1) BootCamp Assistant, split 250GB SSD evenly for both Mac and BootCamp partitions

      2) Disk Utility

      Both partitions show up in Disk Utility

     

    THE PROBLEM I HAVE:

     

    Upon reboot through BootCamp Assistant partition, the following error appeared:

     

      No bootable device found -- insert bootable disk and tap any key

     

    When I reboot holding option, neither the bootable USBs I created nor the BootCamp partition appear as boot options.  They also do not appear under System Preferences > Startup Disk.  However, they do appear in Disk Utility as valid partitions/disks.

     

     

    THINGS I HAVE TRIED:

     

    — booting into disk utility mode by holding down the option key

      tried booting before AND after inserting the USB

     

    — different flash drives by different manufacturers (all USB 2.0)

     

    — different methods of creating bootable disk, as described above

     

    — editing the Boot Camp Assistant “.plist” file (see REF_1 below for file contents)

     

     

    THINGS I HAVE NOT TRIED:

     

    — removing my HDD and returning my original superdrive to the optical drive bay, then recreated partition to install Win7 using legitimate installation disk.

     

    — WinClone worked well for me long ago to resize my HDD partitions, but it only works with NTFS and I would like to avoid that and stay with FAT because I have read many threads warning about Yosemite SSD BootCamp issues with NTFS.

    1. You will need the SSD in the main bay and Optical drive in the OD bay to get a new copy of Windows installed.

    2. If you have not had any issues with NTFS/W7 on the HDD, what type of issues are you expecting with this configuration on a SSD? Curious about the threads you have read, can you post some links?

    Hi Loner T, I was wondering if you assist me with a similar problem I'm having? I have been searching the forum and found many of your answers and fixes to be very helpful but I have got stuck up to a certain point that I cant find a solution for. I have started a new thread here - How do I run Win7 Startup Repair from USB to repair Bootcamp installation?

     

    Any advice you could provide would be greatly appreciated, many thanks...

    1.  I currently have the SSD in my main bay and the HDD in the OD bay.  Are you suggesting I try returning the OD to its bay and try using an install disk?

         I'd like to avoid this since everything is already in place, but it may be the only solution because the computer may be expecting a CD and not USB.  Can you tell me if that's true from my info.plist file contents and terminal results?

    2.  I guess I was reading issues that Yosemite has with NTFS but there may be workarounds (terminal and programs).  Here were the threads:

              http://apple.stackexchange.com/questions/152661/ntfs-usb-drives-on-yosemite

         I also just read that Windows uses NTFS.  Do you recommend using NTFS instead of FAT?

    1. Macs which originally came with a built-in OD are asked by BCA to boot from the OD. If it is missing, you will get a "no bootable device" error. If you can put the OD bad in the Optibay, it will make it much easier to install Windows.

    2. The USB devices are used during installer to contain the Windows Installer. BCA will create a FAT partition on your designated Windows partition, but the Installer re-formats it to NTFS. Apple NTFS driver uses it to show the bootable drives in System Preferences -> Startup Disk under Bootcamp 5. There is some support for FAT for Windows XP if you do have a WXP installation.

    Well I guess I had read threads on issues of writing from Yosemite directly to NTFS but I'll be using Tuxera to write from my Mac partition if need be.

     

    I bit the bullet and replaced my OD in its appropriate bay, repartitioned and installed through BCA, updated from Home to Professional, and now it works perfectly.  The OD replacement was very quick; I didn't screw it in all the way and replaced my OWC data doubler frame with my old HDD.  The process was very quick because by now I've had practice disassembling my laptop.

     

    I would have liked to learn to do it without replacing the OD but whatever worked was fine by me.  And you're right, it formatted to NTFS during installation, guess FAT is only for WXP.

     

    Thank you for your help!

    Please be aware that Tuxera has two issues.

     

    1. Check if it supports CoreStorage.

    2. Tuxera is know to interfere with Apple NTFS and causes problems for System Preferenes -> Startup Disk (as documented at http://www.tuxera.com/products/tuxera-ntfs-for-mac/faq/ ).

    Just as a followup, I was able to simply use an old USB 2.0 adapter (1 port to 4 port unpowered) and plug my USB 3.0 drive that I created from Boot Camp Assistant into it, and in turn plug that 2.0 adapter into the MacBook Pro's USB 3 port.  Installer can see it now that it's acting as USB 2 and the install goes on about its business installing Win 8.1

     

    Cheers.

    Hello,

    I have a similar problem, I would be happy if you could please help me.

    The steps i went through...

    1) I created a windows 7 install disk on my flash drive

    2) I created a partition for boot camp using Boot Camp Assistant

    3) The system restarted and i got the error : No bootable device : insert boot disk and press any key

    4) i restarted pressing the option key, there are three bootable options, "Mac OSX", "Recovery 10.10.3", "Windows"

    5) I start windows, but get the same error.
