Q: Yosemite/Boot Camp installation hangs.

I had previously set up Windows with Boot Camp before moving to Yosemite and all seemed to work well.

When I no longer needed Windows I deleted it.

I am now trying to reinstall Windows ( I need to somehow update the firmware on my self-installed Crucial SSD, which apparently I cannot do under OS X) but cannot get to the actual Windows install stage of the process. The machine seems reluctant to boot to Windows for the set up.

Boot Camp successfully creates the Boot Camp partition and the USB memory stick with the Windows ISO and support files.

At this point, a message box pops up asking if I want to continue or abort, but before I can do anything the system shuts down and restarts.

On restart, there is no WiFi connection, but otherwise all seems to be OS X normal. There is no pending Windows installation, and on starting Boot Camp all I am able to do is remove the Windows partition.

I tried a reinstall of Yosemite which seemed to go well, but the problem remains.

A very small version of the above mentioned message box seems to remain in the system and appears at certain points. That just confuses me!

 

The system is relatively new and shouldn't have and oddball utilities or drivers so I'm a little baffled.

iMac (27-inch, Late 2013), Mac OS X (10.0.x)

    Does the CD/DVD (or the USB) show up as bootable disk when you power cycle the Mac and hold the Alt Key? The Yosemite installer should be a GPT files system.

    The DVD drive has never shown up as bootable, but then I don't have any bootable optical media.

     

    The Flash drive only shows as bootable with the OS X installation partition. Nothing else has worked.

    Can you download a Windows 10 Preview ISO, burn it to a DVD and test your USB Optical Drive?

    Happening as I write.

     

    What exactly should I be testing?

    1. If you use the Alt key, does the DVD media show up as a bootable device?

    2. Can you post the output of diskutil list with the Crucial media inserted in your BD drive? If you pick the appropriate diskN (which is the CD/DVD media), you can also post the output of sudo gpt -vv -r show /dev/diskN where N points to the Crucial installer.

    No, the optical drive never shows as a boot device.

     

    diskutil list as follows.

     

    /dev/disk0

    Do you want to try the following procedure on your USB?

    I've been playing around and have managed to create a bootable optical disk.

    I've set up Windows 10 in Boot Camp and used Macrium Reflect to create a rescue disk.

     

    This appears as a bootable disk as soon as it loads up and allows me to start Windows directly from OS X in rescue mode with quite a few rescue type facilities including a command prompt.

     

    Now I need to find out how to use this to update the SSD firmware from here.

    You can also try Live CDs like Knoppix to boot from and try to update firmware, if this method fails. If W10 is up, check the Crucial website for Windows utilities to update firmware.

    Things have moved on (a little).

    I have managed to boot into Knoppix, but the program just seemed to hang and I had to switch off to get out.

    I also managed to boot from the Syslinux CD which also contained the firmware upgrade.

    It tried to run it, but there was some kind of issue which I couldn't pick out from the screen full of text and it apparently crashed.

    I seem to have found a method of locking the Mac into loading from the CD regardless - it requires a complete mains power off to get back to normal.

    I'll keep trying. There is obviously a way somewhere.

    The W10 solution from Crucial is their Windows update program. It runs and then reboots the system to do the upgrade. At that point their is a problem described as a corrupt OS or missing software. It then reboots back into Windows.

    I can only assume it's a function of Boot Camp emulation.

    Still trying.

     

    I have so far managed to create a Ubuntu installation on DVD and have booted and installed Ubuntu by devious means.

     

    I have also managed using similar devious means to boot using the Crucial supplied update but unfortunately this crashes.

     

    I have taken a pic of the screen - I think it's Crucial's issue.

     

    Any thoughts?

    You may want to ask on Crucial forums on the HMA (High-Memory Allocation) about appropriate values to make their software work.

    I have posted a question for them. Let's hope they are more helpful than the Crucial rep I has a long live chat with!

    He told me that there was no way to do it.

    He is incorrect.
