I decided to change my netbook harddisk after the machine became so slow and cannot load Win 7. After I place my new HDD into my machine (I upgrade from WD 320GB to Toshiba 500GB), I was prompted to set the bios. After I set the bios successfully using my netbook keyboard, I have difficulty to change boot priority order to install win 7 from USB Flash Disk (Kingston 8 GB). I already formatted the FD to be bootable. The problem is either if I press F2 or Tab key, but the BIOS didn't came up. I do not know if the problem is on my keyboard or anything else, because when firstly I used my keyboard to set the BIOS (CMOS date/time), the keyboard worked perfectly. Anyone HELP ME PLEASE.
