Hi, I'm trying to do a clean install on Windows 7 64-bit on my laptop. I currently have 32-bit Vista running. I initially created a new partition, copies all my data there, then started to do the custom install. I got the message: Some Googling around found the following suggestion: I have tried to go in to the start-up options but I don't see this option. I just keep getting back to the above error message. I have since deleted my extra partition, and intend just re-syncing my laptop's data via Dropbox (9GB - hope it will be ok!). Any suggestions how to get this install working please? Thanks!
