Windows 7 install on Mac error 0xc0000428

Hello,

Thank you for posting your query in Microsoft Community.

I understand your concern. However, it is not recomended to install windows 7 using unsigned drivers or files not digitally signed, especially files on DVD or other external drive. In your case, I would suggest you to contact Apple Mac support for better assistance on installing Windows using Boot Camp.

Boot Camp - Apple Support

Hope this information is helpful. Do let us know if you need any further assistance, we will be glad to assist you.

Which model Apple Mac do you own? Some recent model Macs only support Windows 8.1 with Update 1 or later while some only support 64 bit versions of Windows.

Check the following page to see if your model Mac supports Windows 7:

I have done that, gone to the Apple store 3 times and talked with their Apple Care people and went all the way to their Sr. Support person. Apple says it is a Microsoft issue since I am installing Windows, which does make sense. Now you are saying that ii is a Apple issue so I am now stuck between a rock and a hard place.

I have an activation key for Windows 7 Home Premium. Since there are issues with the install of Windows 7, is there someone I can contact and download Windows 10 instead? I can have them verify the key, download Windows and install Windows 10 instead which may work better. I have seen many people with the same issue and nobody seems to have a fix.

i need help with this same problem. ive attached a pic of the error message

i am using a Late 2013 13inch macbook pro retina.

i purchased a windows 7 home premium 32bit OEM disk with product key, but because this mac cant accept disc i used an .iso image and followed the bootcamp steps for mac. 

can you help?

oh i also have desktop that has a CD drive, im wondering if i should insert the disc into the desktop (it already has windows 10) and try create an .iso image directly from the disc? any thoughts. i wasnt sure though, becuase i was worried if i put the disc into the PC then it might think that i am trying to installing on the desktop which i dont want to do.

found a soluition

Hey guys user CofC-Tech solved this for us in another forum so I thought I'd just post it here.

1. Restart, boot to Mac OSX
2. Install the trial of Paragon NTFS.  Restart and boot to Mac OSX again.
3. Navigate to BOOTCAMP/Windows/System32/Drivers
4. DELETE AppleSSD.sys
5. Restart and boot to Windows

Cheers!

Remember, once you get into windows to go into your USB flash drive and click the setup.exe to install all the drivers so that everything works.

so it worked perfectly until it came ot the point for me to put my priduct key in. it turns out that windows 7 product keys are separate for 32 bit and 64 bit

 :( 

Hi, 

After deleting applessd.sys windows installation moved to next step yet not finished since keyboard and trackpad are not working. Please guide me

It is apple's fault as they forgot to sign the driver and you need to download an old version of the drivers which are signed. Here is a link to a thread on it https://discussions.apple.com/thread/7171397?tstart=0

My hanks for the reply, but the problem was solved by just waiting for the apple update for the latest bootcamp 6 to appear on my Mac, once it came I downloaded and all drivers were updated automatically. I think there was a lot of people waiting on this download and that's probably why it took a while to reach me.

But if anyone is reading this, make sure you have updated you bootcamp in OS to the latest version so you get the latest windows 10 drivers.

or you may encounter problems similar to mine, where I couldn't control the back lit keyboard or screen bightness from the keyboard.

hope this helps
