I have a Windows 7 .iso
I always use for BootCamp installations. It works.
I have a MacBook Pro Retina 15" Mid-2014, and I have installed Windows 7 in it successfully in the past. Throughout the latest months, for a number of reasons I have uninstalled the partition, and installed Windows again, and uninstalled again, and so on.
Today I currently don't have Windows installed, and decided to do so. The installation was apparently successful as always: BootCamp partitioned around 40GB for Windows, downloaded the Support Software, booted from USB flashdrive, and then it restarted (as always).
But then, when my Mac tries to boot into Windows, it doesn't seem to work anymore. I am met with a black screen and the following text displays:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
- Insert your Windows installation disc and restart your computer.
- Choose your language settings, and then click "Next."
- Click "Repair your computer".
If you do not have this disct, contact your system administrator or computer manufacturer for assistance.
File: \windows\system32\drivers\AppleSSD.sys
Status: 0xc0000428
Info: Windows cannot verify the digital signature of this file.
Now, something different must have happened compared to all the many times I installed Windows on BootCamp... I do have an idea. The last installation was removed by deleting the partition using Disk Utility (instead of using BootCamp assistant). That's the only difference I can think of.
I have read that I could delete the AppleSSD file. And I did. But now many things seem to be wrong: for starters, the OS doesn't seem to be able to connect to my Wireless network (so it seems like the drivers were not properly installed).
What should I do? I deleted the partition and tried again, but the same occurs. A friend has another .iso
I borrowed, but it didn't work either.
The problem can't be with my .iso
- I've used it so many times before. It works fine. Something must be wrong somewhere else.
I am using OSX Yosemite.
Edit
As requested, I deleted the Windows partition and ran diskutil list
:
/dev/disk0

0: GUID_partition_scheme *251.0 GB disk0

2: Apple_HFS Macintosh HD 250.1 GB disk0s2

Then sudo gpt -r show /dev/disk0
