    When I format it to NFTS / uses the win 7 tool (which format to ntfs) - the starting process doesnt stop at the usb, it doesnt says invalid partition table - it just continue to the windows (even due the hard disk not on the boot priority sequence)..
    Try to boot without usb stick inserted. Then it does boot to harddisk as well?

    Yes the windows come up. The boot order is:
    USB-HDD
    CDROM

    AntiLopa,
    A motherboard doesn't "recognize" disk formats.

    Your motherboard has absolutely nothing to do with your problem.

    Use DiskPart to format the drive as ntfs by following the procedure given in the tutorial on this subject or if you like here is another writeup on the topic:

    PREPARE A UFD FOR USE (USB FLASH DRIVE)


    Run CMD.EXE as administrator

    Type following commands and hit ENTER key after each command.
    DISKPART starts the DiskPart program
    LIST DISK shows numeral assigned to disks
    note the numeral assigned to your usb stick
    The numeral 2 will be used in this example
    SELECT DISK 2
    DETAIL DISK the info shown will confirm the correctness of your selection
    CLEAN ALL the entire usb stick will be overwritten with zeros
    This can take awhile if usb stick has large capacity.
    Keep the faith-the DiskPart prompt will eventually return.
    CREATE PARTITION PRIMARY create a primary partition on the USB stick
    FORMAT FS=NTFS format the partition
    ACTIVE the partition can contain operating system startup files
    ASSIGN the next available letter is assigned to the USB stick
    EXIT exit from the DISKPART program
    EXIT exit from the command shell

    Not sure the OP is having a problem installing Win 7, that comes later. He's having a problem loading the INSTALL FILES on a USB stick, ISO to USB stick.


    Which IMHO is a computer problem as anyone with a properly functioning PC can create the Win 7 Install USB thumb drive. Even if they aren't running Win 7 on the PC.

    change boot order temporay to CDROM only and reboot. Even then it boots from HDD (with usb stick disconnected)? If so... bios setting is not working.
