ok I just made my life more difficult. my mom owns a very old laptop Pentium M 1.6. Forgot her administrator password. So i took the opportunity to format it since it's very slow. Laptop didn`t come with cd-rom, So i made a bootable USB drive with window XP ISO Once in Window XP installation, I wiped up the current partition and create a new one but setup says that the disk might be faulty or SCSI driver related problem when i tried to do a new window installation. So I thought I restart and boot with more drivers but now i can`t boot via USB!!! as there is no more selection for USB. My options available now during booting. 1. Internal HDD ( which i wiped out earlier ) 2. USB <but it's gone now> 3. Cardbus NIC 4. Onbroad NIC I did went into the BIOS and put USB as the first drive to load but it somehow won`t boot VIA USB anymore. So my question is, Is it still possible for me to boot VIA USB ? before i google other methods.
