Topic: Trouble Booting Windows after Partition Resize

I have a PC dual booting OSX and Windows 7. I need to resize the windows partition to create a partition that OSX can use. The resizing worked fine, but I'm having some problems with booting Windows 7. I have a Windows 7 x64 install cd, and I also have an external USB drive with a Windows 7 x64 install partition. After the resize, when I choose my windows partition it goes to black screen with a blinking cursor in the top right. Hangs there. IF i choose the Windows install partition on my USB drive, it boots into my main windows partition just fine. Weird? If I boot from the Windows install CD, it takes me to the install screen. I've attempted to repair my windows install from here, hoping that it would fix a BOOTMGR problem, but it tells me that no problems were found. I have also attempted to use the command prompt from the repair screen, trying to see if I could fix it there with the Bootrec.exe tool. That doesn't work at all. When I try any of the fixes, it tells me that the path doesn't exist.

Again, I'm on my windows partition now. I can get it, but definitely not optimal.

Re: Trouble Booting Windows after Partition Resize

After resizing the partition, did you try running "sudo gptsync /path-to-your-disk-device"?
Where /path-to-your-disk-device is something like /dev/sdb

Also what tool are you using for your boot loader so that you can run two operating systems (rEFIt)?
