In recent days, many are switching to netbook. Compared to laptop, it is compact and lightweight. But netbook does not come with a DVD drive. If the preloaded operating system is corrupted or it is not the OS of your choice, then installing OS becomes a little complicated task. You need an external disk drive to boot from CD. There is also another hassle -free option – boot from your USB flash drive. But the USB flash drive can’t be used as such. It has to be first converted into bootable.
