how to install Ubuntu 11.10 along with windows 8? i installed Ubuntu 11.10 along with windows 8, where i kept the boot mode in legacy. after successful insulation of Ubuntu when i removed boot media(DVD) it shows the message as "NO OPERATING SYSTEM FOUND" and it could not open either windows 8 or Ubuntu. I again changed boot mode to UEFI then windows 8 was open. but it won't show the ubuntu.
