Hi, I don't have blank dvds but i have a few flash drives which have enough space for the iso and I used isotousb to make 4 bootable usb. Then I was able to boot the first usb and start the clean install but on the half way, it did not prompt any option for me to choose and continue with my second usb, instead it eject my optical drive which is so useless... Someone please help me with this problem. I thought of changing something in the iso eg: recovery.ini may work but I don't know which and what to change. Thanks in advance for those who would help me.
