Reformatting without floppy, CD-rom
I need to reformat my sony vaio laptop, however, the sony does not have a cd-rom or floppy drive. I have a boot up disk, and boot up cd-rom, however the laptop does not boot from a usb cd-rom or floppy drive. Is there any way I can make it boot from usb cd-rom or go about to reformat my computer? Thanks for any help in advance!
