oh, because i have my Mavericks installed on disk0s7. BTW i have my windows 8.1 on disk0s1
Yep, you were right, but for some reason for the step before th last on which is reboot, i typed in rm -R /boot /Extra And it said no such file i think, would that affect it?
By this i meant i could no longer see Windows boot manager in bios, i tried to boot into windows using the OS button from the boot menu, and it gave me an error
... and btw it still is flickering when i don't boot into safe mode...
Tried the boot menu hotkey, I can't boot without my USB (external hard drive) now, however i can run it and eject my external, and i can't see windows boot manager, so what next? I will post IOReg of the flickers and such in a moment...
