I have computer dell inspiron n4030 with running in windows 7..recently I interested in windows 8 therefore I try to upgrade it myself with a windows 8 setup copy to USB drive (already bootable using novicorp). But when I try to boot the computer with usb drive inserted using f12 boot option I choose usb boot..then its appear only black screen and 'underscore blinking'. I wait it for hours still same. I already tried to install the latest version of the bios from A06-A07..but still the same result. All method on installing the windows setup using usb drive is correct because I already done it with another dell inspiron laptop.
Please do give me solution to this problem.Thank You
