Hey guys, I've been through hell lately trying to fix this issue. I had windows 7 installed before, but I deleted it because there was an issue in the system which prevented me from using 3DsMax, anyways, after I deleted it, I tried to install it again through bootcamp, but I was stuck at the blinking-dash problem. So what I did was, I searched around and found a fix for it the "MBRFAT" fix. After I did that, to my surprise, the blinking dash disappeared. But of course, a newer problem came out, the "CDBoot: Couldn't find Bootmgr". By the way, I am using an external dvd-reader, because my internal one isn't working (Another problem that I faced while trying to install, so i was forced to buy an external dvd reader). I tried to search around for a fix, some people said I should hold option key and get in the windows 7 install, but it didn't work. Others said I should attempt to install from a USB, it didn't work (I removed the partition, and re-did it through a USB, the option for creating a USB install iso wasn't there but I found a fix for it on youtube, by changing some strings). I've tried every fix out there, but I seem to find no way to fix this ****** problem. And "NO, I WILL NOT USE VMWARE, OR ANY VIRTUAL WINDOWS PROGRAM."
