Hi guys, Sorry if this is the wrong forum for my problem. I am trying to boot a rescue cd from hard drive at startup(using grub) since my cd drive doesn't work anymore. I have an old pc which is infested with malware and would like to clean it up without resorting to a clean install of windows. I am not able to run either MSE or MBAM because of the virus and also the pc is slow with only 256mb ram. The bios doesn't support booting from usb either. This is the guide i tried but didn't work, "thinkweird.info/1688/running-hirens-bootcd-from-hard-drive" I followed the steps but when I select the desired option from boot menu, the computer just restarts. What could I be doing wrong?
