are you getting an upgrade or full version of 7.
Still 10 days to go so no hurry to remove the RC it only takes a short time to format the partition.
If you are upgrading, type "msconfig" in the search box without the quotes, click on the msconfig file that comes up, go to boot options make Vista first boot, delete the Windows 7 reference.
Restart in vista format the W7 partition, run the W7 upgrade from Vista. Or you can use the custom install option to clean install the upgrade and choose to keep both partitions, or delete both and create one single one, remember to backup your files first.
I currently have a dual boot of windows vista premium x64 and windows 7 x64. I am getting Windows 7 ultimate, and I was wondering if I should remove the windows 7 partition that I have now, or if I can just format everything into one partition when I install the actual version of Windows 7.
