Windows 7 Installation Problem

Alright I used my custom built computer to install Windows 7 on a partion created by Disk Utility. So my issue is after I put the hard drive back in my laptop. When I tried booting into Windows it flickers then reboots the Mac. I installed the Bootcamp drivers when I installed Win7 using my custom built. Is there anyway to fix this issue?

MacBook, OS X El Capitan (10.11.3)

Hi D3ATH2020,


It sounds like you installed Windows 7 onto a hard drive using a separate PC (Windows) computer then wanted to use that hard drive with Boot Camp on a Mac.


Rather than installing Windows using a PC, try installing Windows on the Mac directly using the instructions for installing it with Boot Camp.

Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support


Take care.

If the disk is in the Mac now, can you post the output of the following Terminal commands?


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0


The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.
