I need some possible suggestions as to why my installation of windows 7 on my mac mini (a1176) with a core 2 duo 1.83ghz constantly gives me the error: 0xc00000e9, despite the number of factors I try to change. Let me start off by sating that I am using a disc to install windows, as on my mac, due to the bootloader this is the only option. Since, I lost my official disc I have made my own, I have used 2 different iso files, in at least 5 discs (separate attempts) for windows 7 home premium 32 bit, and still I get the same error. I thought after this, that the problem might be my disc drive, so I used an external one and I still get the error.
Any suggestions to why I keep getting this error?
I am running os x 10.7, and using bootcamp 4.0

Where did you get the ISO files from if you lost your disk? A bad ISO file could very well give you that error. The disk you made from the ISO... is it able to boot your Mac or a PC?

I used one of the ISOs before to install windows on a laptop and it worked fine.

Are you installing to a BootCamp partition on your primary OS X drive?

Are any other disk drives installed in, or attached to your Mini? Can you temporarily disconnect them during the install?

You also might check Google for answers: Windows Error 0xc00000e9 mac
hmm, now that I think about it, is it possible my wireless keyboard and mouse could be causing this? They're not bluetooth, but infrared and use a usb adapter.

Windows 10 refused to complete the installation over and over again on my dual-drive 2012 Mac Mini Server until I opened it and unplugged the other disk drive cable ... then it completed without issue. I don't recall the error code it threw. Once installed, I plugged the drive cable back into the motherboard and it all ran without further issues.

I had not had any issues with previous versions of Windows however, and was upgrading from Windows 8.1 when I experienced this problem.

I'm going to try that now, and use an external disk drive instead. I'll report back once I'm done

I don't think Windows is going to allow you to directly install to an "external" disk drive. I have run Windows externally by first doing a standard BootCamp type installation to the primary drive, then using WinClone to move that installation to the external Thunderbolt SSD drive, and then deleting the BootCamp partition.

I think you are installing Windows 7 here. However, with the Windows 10 upgrade, even on my genuine BIOS Windows PC I had to temporarily disconnect all additional drives except the installation drive to get a completed upgrade installation.

Thank you very much for this suggestion, it worked for me, and after 6 relentless months of trying to get windows on my mac, I now have it installed.
