Avast BART CD iso to bootable USB.
I have tried unetbootin (several versions), other third party software, xcopy commands and checked other EE answers in the knowledge base. I am able to copy the Avast BART CD contents to a USB drive (NTFS and FAT32) but it just won’t boot. I know from past experience, some software just is not USB boot friendly.
Heeeeeeeeeeeelp! :-o

I was able to create a bootable USB in Windows 7 (not XP) and successfully copy the Avast files from CD to USB. I attempted to boot to the newly created USB from different PCs (running XP and Windows 7). Each time, the USB booted and I saw the Avast startup screen but then the screen went black and looped back to the (Dell) startup option screen.
It appears as if the Avast software is looking for a file or program on CD, not finding it and restarting. My guess, (just a guess) is that one of the files like bootfix.bin is the issue. If this is the issue, can this be resolved by using a hex editor to change bootfix.bin?

Meagain35’s link to http://www.intowindows.com/bootable-usb/ was perfect for creating the bootable USB. Noxcho’s comment was also correct. The boot looping is an Avast issue and from checking multiple Avast blogs, the best explanation for the lack of Avast’s USB boot-compliance is because USB drives are writable and therefore potentially vulnerable to a virus/malware file writing to it.

Thanks everyone! This still helped me create some additional PC recovery options :-)

Download trial - install - run it - Tools - Recovery Media Builder. There is option to create USB boot drive. You can add there user specified ISO. Maybe this could help.
