I'm literally tearing out my hair at this issue. I've been working on it for soooo long but still havent found a solution.
i have two seperate SSD's in my comp - OSX Mavericks and W7. Last month i installed Mavericks with chimera as bootloader, then installed windows 7, and set bios to boot to OSX disc and all was working perfectly.
OSX could boot fine and W7 could boot fine (from chimera screen).
Recently I had some issues with my windows 7 build and to cut a long story short I lost the boot loader. I can boot the machine to the normal chimera bootloader offering OSX and W7 - when I select W7 it give the very annoying screen below and I have to reboot.
I've booted to a windows recovery usb, it found 'startup problems' and attempted a fix. However when I reboot without bootable USB I still get the same screen below.
I've tried to manually fix the boot record from the command prompt in the startup usb;
