How to uninstall win7 from windows triple boot and upgrade vista to win7?
I have a triple boot of Windows XP, Windows 7 RC and Vista in three different partitions with Vista set as the default OS. I had XP first and then installed win7 RC and then Vista. Now I want to uninstall win7 RC and upgrade Vista to the retail version of win7. I have Easy BCD installed in win7 RC. According to apc Magazine, to uninstall win7, I have to uninstall the vista bootloader.
(to remove the Windows 7 boot manager – in EasyBCD go to “Manage Bootloader”, select “Uninstall the Vista Bootloader” and then “Write MBR”. At the moment EasyBCD isn't aware of a distinction between Vista and Windows 7, but using this option still works fine)
I want to know if I uninstall the vista bootloader, will the bootloader of Vista be uninstalled along with win7. From which OS should I uninstall the vista bootloader for win7 using Easy BCD: XP or win7? If the bootloader of Vista is also removed, then how can I again make the bootloader? Will I use the method told in apc magazine(*apcmag.com/how_to_dual_boot_vista_and_xp_with_vista_installed_first__the_stepbystep_guide.htm?page=4)? Is there any other method for uninstalling Windows 7 RC?
After I upgrade my Vista to win7, will the programs and games installed in Vista work or do I have to install them again? Will the documents and files in the drive in which Vista is installed be deleted in the upgrade process?
What is the difference between Windows 7 RTM and Windows 7 Retail? Is Windows 7 RTM the Retail version?
