Hi This is now few days I try to install Win7 from USB on MBP 15 i7. I used the Windows 7 USB/DVD Download Tool Help to create my USB stick. I was successful to install it on my brothers 27" iMac using the same process but Im having problem with my MBP. I create the BootCamp partition 100GB and installed rEFIt. Each time I try to boot of USB I get: No bootable device -- insert boot disk and press any key I don't have the DVD-DL disc to burn the ISO but I'm afraid that I will get the same error.
