I am trying to install Windows 8, efi, on my SSD. I am getting the error code:

 0xC0000005 "Windows installation encountered an unexpected error. Verify that the installation sources are accesible, and restart the installation everytime" 

I have tried all the solutions on this thread: which is basically try formatting exfat, then installing; the setup stops at 89% in step2 and gives the above error. I also tried the procedure here: I get the error code above in step1 of the install.

diskutil list:

  • welcome, as you could guess your problem is not very common around here, so it might take a while till someone can answer it.

  • @ArnavShah Please add your current Mac OS X and the output of diskutil list and if applicable diskutil cs list entered in Terminal.app to your question.

  • @ArnavShah ...and examining the diskutil listings probably Yosemite as current Mac OS X ;-)

  • @ArnavShah Did you already try this solution?

  • I did try something similar, the only difference is I used cmd after clicking the efi boot icon.

Sorry, I don't have a solution. I do have more questions.

You seem to be trying very hard to use the GUID partition table to boot Windows. Most Windows users just rely on the MBR in the hybrid partition table. Why do you feel you need to make the extra effort? What do you hope to gain?

Is your Mac a MacBookPro9,2 (13-inch), MacBook9,1 (15-inch) or MacBookPro10,1 (Retina)?

Do know if your firmware is up to date? See EFI and SMC firmware updates for Intel-based Macs.

I assume you are booting from a flash drive to install windows. How did you create the flash drive? Did you need to modify the Boot Camp Assistant?

Could you post the output from the following commands? The commands do not alter anything.

sudo fdisk /dev/disk0
sudo fdisk /dev/disk1

Which Windows: 8 or 8.1? 64 bit or 32 bit? Full or upgrade version?

OS X is Yosemite?

You are using Core Storage. Would you be opposed to not using it. I don't know what good Core Storage is unless you have a Fusion Drive.

Have you configured the OS X Disk Utility application to display hidden partitions? If not, see View & Mount Hidden Partitions in Mac OS X. I do not want you to mount the hidden partitions, just make them visible.

You say you want to install on disk 0. You seem to have collected some partitions on disk 1. Do you need help removing them?

Finally, you may discover you can not install Windows because you removed the DVD drive.

  • Ended up swapping the harddrives; have to wait for EFI boot to end or hold option to boot in Windows =/

  • @Arnav: So I assume you now have windows installed using EFI boot? If so, is having to hold the option key a problem? There are utilities to help with that. A free one is rEFInd and a $10 one is Boot Runner (14 free trial). Also, I assume you know how to boot between OS X and Windows without having to hold a key down. Feb 20, 2015 at 23:49
  • I installed Windows through the Windows USB icon (not the EFI boot one), so I'm not sure if there was even an EFI partition installed. I tried doing the first step on this page,mountvol S: /S, but I got an error: "The parameter above is incorrect."

  • @Arnav: An easy way to determine whether you installed Windows in EFI is to use this test. If you get a * in the Gpt column, then you succeeded. My guess is you did not, which would make Boot Runner a better choice as a startup manager. Anyway, I do not use either and rely on Boot Camp in Windows and System Preferences in OS X to switch operating systems. Feb 25, 2015 at 7:00
