Make USB pen drive as a bootable device (RedHat)

If you cannot boot from the DVD/CD-ROM drive, but you can boot using a USB device, such as a USB pen drive, the following alternative boot method is available:

To boot using a USB pen drive, use the dd command to copy the diskboot.img image file from the /images/ directory on the DVD or CD-ROM. For example:

dd if=diskboot.img of=/dev/sda

Your BIOS must support booting from a USB device in order for this boot method to work.

But this only in case of only one drive in your hard disk, in case of if you have more than one partition then mention partition name for example /dev/sda1,/dev/sda2 etc..
