hi to all I have another weird thing to ask hehehe I'm trying to boot from my USB pen drive. I know my mobo (ECS K7S5A) allows it and all BIOS options are fine. I used several techniques to make my USB drive bootable and the images were always OK (I mean were really written to the boot sector & stuff) But it happens to never work I tried Win98, DOS, Linux boot images and neither of them works ... The pc searches for boot sector and then directly switches to HDD boot.ini menu Any ideas ???
