Dual boot with Win 7 32 bit and 64 bit on 2 seperate drives

Because of one piece of necessary software that will only run on 32 bit Win 7 I am needing to dual boot between Win 7 32 bit and Win 7 64 bit.  I have installed Win 7 32 bit on Drive 1 which is in SATA port 3 and I have installed Win 7 64 bit on Drive 2 which is in SATA port 4.  I can run the 64 bit if I disconnect the 32 bit from the port but if I connect both of them only the 32 bit will boot, not the 64  bit.  I was expecting Windows to give me the option.  I have set the bios to boot on the HDD first.  Anything else I need to do?

Most mobos will give you a Key to Press to get you to a Option screen to pick which device to boot from, during the bios bootup.

Check out the docs on your motherboard.  Usually there are sata ports 0-3, so since you have port #4, you could have a controller that does things with ACHI, or if port #4 is being used, the other ports don't work, or could have RAID drivers kicking in, etc..

Easybcd does work well and is easier then manually editing the bad file. However, if your computer is running 4gigs of RAM or less, it would probably be easier, to just run 32-bit for everything.  The only advantage to 64 bit software is support for greater then 4gigs of ram, and 4 gigs of virtual memory.
