I have an old hard drive with Windows XP on it and I wanted to use it in a build. I then put it into the new build and of course windows doesnt boot up because its tied to the old motherboard which is trash now. So I burned the ISO file for Unbuntu 14.04.2 on a DVD-RW trying to get the Ubuntu OS on it instead of Windows XP. When I start up the PC, its automatically says I cant startup windows even when I try to change the boot first to CDROM instead of the HDD with windows on it. HELP?
