Hello! I'll go ahead and tell you my motherboard, cpu, and HDD: Asrock Pro3 Z75 i5 3570-k WD6400aaks (caviar blue) So i've done some extensive research on this, but all for naught, so i seek the help of the masters. I am trying to install windows 7 from a usb. All goes correctly until the installer asks which partition i would like to install to. I click on my HDD. It is a clean drive, no hidden partitions, just one big partition that encompasses the entire drive. I hit next, and at the bottom in small text it says "setup was unable to create a new system partition or locate an existing system partition." Here is a list of some of the many "solutions" i have encountered: 1. Disconnect all HDDs or SSDs than the one you want to install to. (I only have one drive.) 2. Set the HDD as the primary boot device. (done this, every time i start up i tell the motherboard to launch from the USB that one time, not to set it as the primary drive.) 3. Delete all the partitions. (Done it.) 4.Remove any USB sticks #4 is my problem. It might solve the problem i am encountering, but for the fact that i have to keep the USB in or i get a completely different error message: 0x80003, which apparently means to reinsert the device that has the windows iso on it. When i do this, it goes back to telling me it can't create or locate a partition. I am about to tear my hair out! Does anyone have a solution!?!?
