Hey guys, I wondered if anyone had come across a similar issue. Vista installed fine, then I came to install Windows 7 (I only have an upgrade key, hence the vista installation). It gets to approx 80% on the expanding features section, then an error message saying (can't remember the exact wording) that some files are missing or corrupt. I've tried a friends Windows 7 disc also but same thing happens. It's probably worth noting that it isn't always at 80% but somewhere near there.
