My laptop came presupplied with a Vista Professional installation and no Vista installation DVD. It has now stopped booting, stuck in a cycle of failing startup repairs.
I have a Windows 7 Ultimate DVD, but when I boot from it and select the option to upgrade an existing Windows installation, it states that the upgrade should be performed from within the existing Windows installation as a live upgrade.
Without being able to load the original Vista installation, how can I perform an upgrade to Windows 7 without losing my user accounts and installed programs?
Although I back up most of my data I really need to get the upgrade working in order to sanity check that I'm not losing anything important.
Thanks in advance.
