A virus quickly fucked over my little Acer Aspire One completely, so now I need to wipe the hard drive with just a USB thumb drive since there's no CD drive. I've tried resetting it from the computer itself at startup but get Error 4, so that's out. Also my other computer is a Mac, so I need to create the USB drive on here... The thumb drive I have is 16GB, so I partitioned it to have a 4GB FAT partition, but I don't know how to boot from that partition anyway..... Any ideas?
