Default Netbook Installer killed Win7 Dual Boot - 11-05-2009, 08:04 PM

I've had the dual boot working for a few weeks. It was working perfectly until I decided I wanted to try to make a few adjustments on NetbookInstaller to make my monitor work on OSX when I plug it in.

I ran NetbookInstaller a few times to get the Mirror files. It took a few tries but eventually my external monitor worked. But now I can't boot into Windows 7 because the boot was corrupted. When I try to boot from the USB to reinstall Win 7 it says BCD file missing. My only option in both cases is to restart, and I now only have OSX SL.

Does anybody know a way to fix this without cleaning out the HD from OSX and doing a fresh install of OSX and Win 7?

I think I just need to boot into Win 7 install and choose repair, but I can't seem to find out how to boot into anything but OSX SL.

Removed Windows 7 and made OSX SL partition bigger.

I don't want to post another thread or go off topic, but does anyone know of any guides for ms-dos operating system and osx dual boot?

There are various approaches, but what I did was run the Win7 repair and then install EasyBCD 1.7.2. Added a Mac boot option and I was done.

Yeah, I wasn't able to load into windows 7 repair either. It kept showing BCD error.

I think I messed everything up more when I removed the Windows 7 partition with Disk Utility. I wanted to make my hard drive bigger, but now OSX turns off at boot. It shows a progress bar at the bottom of the spinning wheel, the bar blinks twice and the netbook shuts off.

Time to start over! :0

I would really like to install a triple boot of Win7, OSX SL, and Free Dos (For writing purposes).

I notice that the triple boot guides are mainly for OSX, Win7, and Ubuntu. I guess I'll see if I can try it. If anyone has any advice, it would be greatly appreciated.

If you don't want to start over/haven't already, most likely you need to set the Win7 partition to active first. Check one of the triple boot thread where we discuss how to do it using diskpart.

This happened to me as I was updating my OSX partition to SL 10.6.2

Ran the Win7 installer. It said I needed to repair boot options.
Booted Win7 and then ran EasyBSD.
Deleted OSX entry, put it back and rebooted.

I was able to boot into OSX again...

One more thing. If you do any messing around with Netbook Installer, just don't re-install Chameleon.

Then the bootloader won't be messed up.

Wish I saw this thread last week. That way I wouldn't have had to install my dual boot setup 3x...

1st time....user error

2nd time...netbook installer caused an error

3rd time...works like a charm over a week and everything's setup exactly how I want it!

Not fooling with that stuff again lol

now can anyone for the life of me explain why my OS clocks are off no matter what time I set them to?

If I set Apple time correct, then Windows is off by 6 hours...and vice versa lol YET my system bios time is accurate
