Cant install windows with usb

ok so iv been having this problem with my laptop

its a sony vaio pcg-7184L

at first it would not boot up and the screen hangs with a blinking underscore

i read that that is caused by a bad formated flashdrive

so i followed at tutorial on how to format using cmd and it worked however it gave me a screen that says windows setup( ems enabled( and x64 recover(ems enabled)

i clicked windows startup and it loads windows files but it gets stuck on windows setup screen..it just loads forever

i used windows 7 usb/dvd tool to make a bootable flash drive

also when i boot up from internal drive it gets to windows loading screen then reboots again...

so what do you guys think the problem is, its been driving me crazy


also before it gets to the endless windows setup screen it asked to choose language and time zone, however i get no option to format hardrive or make a partition.

so ty in advance
