Amnesia United States3818 Posts May 28 2010 12:31 GMT #1 Long story short I was trying to fix a rootkit problem and the person helping me on bleepingcomputer told me to run ComboFix. Too bad after I ran it I couldn't start up my computer because compbatt.sys was missing. I'm waiting for his response but it's taking forever.. The reason I must use my usb is because my laptops optical drive wont fucking load meaning when I put in a CD it won't go in =\ I have the Vista Recovery .iso and my USB but despite reading some guides it's not working properly, or at least I am doing something wrong. I know for a fact my computer has a boot usb option since when I press f12 it gives me several options.

Your computer can't intrinsically read .iso so you'll have to extract the contents and place the boot files in the root directory of the USB http://www.bootdisk.com/pendrive.htm

This is the most simple method for creating a bootable USB I have found - hope it helps. http://wintoflash.com/home/en/

Amnesia United States3818 Posts May 28 2010 17:38 GMT #6 Managed to fix it by using this guide: http://www.maximumpc.com/article/howtos/how_to_install_windows_7_beta_a_usb_key @SLTorak.Hobo: I couldn't use it - it kept asking me to find the Windows 7/XP installation folder. ;p

SLTorak.Hobo Canada67 Posts May 28 2010 17:57 GMT #8 Not that it will help now but did you mount the ISO file with Daemon before you ran the wizard then selected the Daemon hosted image as your source? Anyways good you fixed it!
