Install from usb key? https://wiki.centos.org/HowTos/InstallFromUSBkey might fit on an 8gb, def a 16gb
Or maybe just dd the install file onto your partition and pretend its a usb key and tell your bios to boot from that partition? dd if=CentOS-6.5-x86_64-bin-DVD1.iso of=/dev/sdb1 note that I put the 1 on the end of /dev/sdb , as you are dd'ing to the partition, not the drive. Worth a try. make sure you get that partition right, so you don't wipe stuff out.
