How to uninstall win7 from windows triple boot and upgrade vista to win7?

6 posts · originally from https://geek.digit.in/community/threads/how-to-uninstall-win7-from-windows-triple-boot-and-upgrade-vista-to-win7.123347/

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 (page 4 of this guide - *apcmag.com/how_to_dual_boot_vista…

Is there any other method for uninstalling Windows 7 RC?

Thanks for any help in advance

The easy way to do it- download and install Vistabootpro in either Vista or XP. From the boot options of vista bootloader delete windows 7.Format partition containing Windows7.
Boot using Windows7 DVD and upgrade vista.

Thanks a lot for your help.

My XP is booting damn slow. So I will firt remove the Windows 7 bootloader by your process and then reinstall XP and et back the vista bootloader through my method. Can your method be used to get the vista bootloader back?

I will install Windows 7 on Jan 1st. New Year, New Windows. 8) UH!

Well can you tell me the process of installing the vista bootloader again? It would be of great help.

In vistabootpro select System Bootloader in top menu and select vista bootloader in menu
under that ,choose for all drives. Click install.
