I have just discovered that I cannot do an Upgrade from Vista HP to Win 7 Pro and that I will have to do a Custom or clean install. That will be OK and doesn't cause any problems.
I have XP on one HDD and Vista on another with dual boot. However I want to replace Vista HP with Win 7 Pro 32 bit, ( I intend to go 64 bit later on).
What I would like to know is, will Win 7 replace Vista on the boot sequence (MBR?), so that on booting the PC I have the option of selecting either XP or Win 7, or will I be presented with a boot menu of XP, Vista and Windows 7, albeit that Vista is no longer installed? If the latter, will this cause any problems in selecting the OS that I want to launch i.e the MBR looking for a now non existing Vista and would there be a way to remove reference to Vista?
