Q: Boot Camp disappeared after El Capitan update

I am a sailor and due to report to my ship & sail out this coming Saturday 10/10/2015.


I have a mid-2009 13" silver MBP which also has win10 loaded using boot camp. The Win 10 side has all my USCG certifications, professional licenses, email exchanges with USCG, accounts, etc.


I downloaded and installed El Capitan and after rebooting, I noticed the option of booting up in Win 10 gone. Pressing the Option key gave me 2 options of booting up either in El Capitan or the Recovery Disk. A friend put in the following sudo command, "sudo nvram boot-args="kext-dev-mode=1 rootless=0” and now the boot select screen does not show that option either.

This is what diskutil list shows:

/dev/disk0 (internal, physical):

     #:                              TYPE NAME                               SIZE            IDENTIFIER

     0: GUID_partition_scheme                                         *250.1 GB    disk0

     4:    Microsoft Basic Data                                             75.2 GB     disk0s4

 

When I type diskutil cs list into Terminal, I get No CoreStorage logical volume groups found.

Typing sudo gpt -vv -r show /dev/disk0 got

gpt show: disk0: mediasize=250059350016; sectorsize=512; blocks=488397168

Also, a few months back I had re-partitioned the hard disk with both Yosemite and Win 7 on it, to make space for Win 10.

How can I undo the sudo command and get back the Win 10 partition? I can't see the Boot Camp/Win 10 partition neither in .

 

Someone has suggested that I use the sudo bless –folder /System/Library/CoreServices –setBoot command. Should I?

 

PLEASE HELP. I need to get access to my documents and co email before Saturday.

 

Thanks in advance.

    Is it a mixed 32-bit and 64-bit DVD?

    The ISO DVD was burnt by my wife on a 64bit W10 Pro laptop and is for a 64bit W10 Pro.

     

    I tried the "C" option. The Win logo came up and gave me another blue screen, this time with another error code 0xc000000d, saying A required device isn't connected or can't be accessed. Googling it figure out how it can be solved.

    Your BCD is corrupt. You will need to use bootrec.exe and use /rebuildBCD. Please see - https://support.microsoft.com/en-us/kb/927392?wa=wsignin1.0 .

    Hi

     

    I figured that out and that' why I was trying to figure out how to reboot from the ISO DVD as even after using the 'C' option, I go straight into the hard disk version of W10 and not the DVD. The link that you gave me says:

     

    To run the Bootrec.exe tool, first start the Windows RE:

    1. Put the Windows Vista or Windows 7 media in the DVD drive, and then start the computer.
    2. Press a key when you are prompted.
    3. Select a language, a time, a currency, a keyboard, or an input method, and then click Next.
    4. Click Repair your computer.

     

    My problem is how to restart in the DVD drive?

     

    Is it possible to dismount W10 and then reboot using the DVD, repair, reboot and re-mount?

     

    The nuke option is for me to wait till I reach home next year, re-load W7 as that's the key that I have, get MS prompt for upgrade & start all over again

     

    Cheers

    No. Try this first.

     

    1. Insert your W10 DVD.

    2. In OSX System Preferences -> Startup Disk select Bootcamp (not the DVD).

    3. Click Restart.

    4. Check if the DVD Installer starts up. Try a SMC and NVRAM reset if it does not and repeat.

     

    Please see http://imgur.com/a/1DaOE#0 as an example of recovering W7. W10 should be very similar.

    Hi

     

    I did and still the same. What's the difference between selecting Boot Camp from Startup Disk and selecting the Option Key at booting up? The end result looks the same to me.

     

    I also did a SMC (Shift+Ctrl+Option+Power Button) and NVRAM (Cmd+Option+P+R (release at the 2nd chime) as you suggested. No luck.

    Hi

     

    Seems like from Googling that reinstalling W7 and then upgrading to W10 due to activation keys problem is my only option, right?

    There is small matter of a BIOS emulation layer called CSM-BIOS and boot order. If your end result is the same, does the DVD show up as bootable when using the Alt/Option key?

    Activation keys should not be an issue. As long as you have had W10 installed and activated in the past, you can do a clean install of W10 again. In your case the 2009 MBP is the most challenging aspect of W10 installation.

    No. The DVD does not show up at all. Neither when using Startup or while using Alt/Opt key. I keep forgetting to mention that. The dir on the the DVD does show autorun.inf.

    Can you right-click on the DVD and select Get Info? What type of file system does it show?

    Apple no longer supports Boot Camp for W10 for mid-2009 MBP. Several workarounds online for this and overcome the keyboard/mouse/speaker problem. What others challenges did I miss? I'd go in for a clean install, but there are other issues to consider, such as some nautical software, printers, Adobe, accounting, Kaspersky, etc to consider .  And, even MSFT has stopped supporting some software. I get by as they are legacy

     

    Nice pickle I've landed myself into

    What is the driver to use W10? Do you have issues with W7? You can also explore virtualization engines, but the critical part is how does the software that you need work with VMs? Does any software need direct access to hardware?

    I dunno. I think I'll write to MSFT and see if I can get the activation key. Else, just wait till I reach home and re-install W7, reinstall the software and then download W10. I just don't want to spend for the mac version of software. I am cheap

     

    Just a bit disappointed that I cannot restart from the DVD. Would the fact that it's DVD-RW and UDF formatted be the problem? Can I copy the disk to the hard drive, reformat the dvd and then recopy it solve the problem. Would it still remain as ISO?
