Windows 7: 32bit 64bit dual boot up

32bit 64bit dual boot up

Is it possible to have dual (or triple) bootup with a 32bit Win 7 on one side and a 64bit Win 7 on the other?

I have dual boot with XP and 32bit Win 7 but will be upgrading to 64bit.

Many thanks in advance...

Yes you can have triple boot without any problem.

Hello mcquicker.

Yes it is possible, first have a look at the info below but if you have only one Hard Disk Drive (HDD) then have a look at the tutorials at the links below to get some ideas.

Dual Boot Installation with Windows 7 and Vista
information   Information

The easiest way to do away with boot issues between 2 separate Windows installs is to use the BIOS one time boot menu to select which OS to boot at system startup.

If you have 2 separate Hard Disk Drives (HDD) and have one or the other installed to one HDD and you want to install the other; disconnect the HDD with the first OS installed on it and leave the HDD you want to install the second OS to connected.

Install the OS to the connected HDD and when complete and the system is booting good, power down and reconnect the second HDD with the first OS on it.

This way the OSs will boot independently of each other and there will be no boot conflicts between the 2 separate OSs to have to sort later.
