Here is the scenario: My computer has one internal harddrive, it's split up in two partitions. On the first partition, I've installed Windows Vista (32-bit), and on the second drive I have various files stored. So, not wanting to overwrite the Vista install, I chose to install Windows 7 (64-bit) on the second partition. At the 'Expanding Windows files' step it hits 84%, and from there is stalls for a long time. Then I get an error about missing data or something similar. Cannot recall what the exact message was. So, I try again, same thing happens. And it also doesn't seem to remove the temporary files after a failed install either. I remove the files with unlocker software, and tries again. It hits 26%, and stays there for way too long. So, I reboot, try to do it on the Vista partition. Same thing happens. Now I'm really unsure about what to do. I would prefer not having to wipe the harddrive clean, though, as it's such a hassle taking backup of everything. Any suggestions?
