Acer has the option to change boot sequence so if he simply copies all file from the iso to the USB from the DVD is the DVD is bootable then the USB will be bootable. and \when all files are uncompressed to the USB it then will function exactly like a HDD, and you can see all files, so he can then run setup and chose upgrade or Custom - clean install.Snuffy; Based on his posts, our teenage computer tech apprentice has an ASUS Aspire One Netbook with a 160GB hard drive, partitioned with XP and 7, that will not boot to either OS. The big problem with fixing this is the Aspire One has no floppy, no CD, no DVD so how would one install an OS from a DVD? Hopefully, he can copy the install files to his flash drive and boot to it. Still, with out something, even DOS, how will he get to the setup.exe to start it? Another cheap option for him is a USB floppy with a bootable DOS disk. With that, he should be able to boot to DOS and find and start the setup.exe on his flash drive.
A more expensive solution is an external USB DVD. Not as cheap. Simple to use.
I think he is on the right track as he is looking at the "install from USB / flash" tutorials here on 7 Forums. Hope it works for him.

If he has options to another computer that has DVD and USB options - copy all files/directores from DVD to USB. simple that is how I did it last nite for my sisters new system.
