Ok well i have Windows 8 installed on a 20GB partition. I can't do anything on ti so i want to get ubuntu instead. But apparently i can't simply uninstall windows 8. When my computer boots, it loads Windows Developer Preview first and gives me a dual boot screen to choose between Windows 8 and Windows 7. If i uninstall it wreck my computer for booting windows 7? Would i be able to: - Delete my partition with windows 8 on it and keep my conputer safe or - Overwrite the windows 8 partition with ubuntu by the ubuntu installation.
