Dual boot win vista 32 bit to 64bit win 7

Hey guys,

some of you probably have seen my other thread regarding this. I had win 7 64 bit then was planing to dual boot with win vista 32 bit but the disc i have is a toshiba one and only does a clean install meaning deleting partition and such.

I recently reformated to windows vista home premium 32 bit. Did the parititon and such, so now i am ready to install win 7 64 bit in a different partition.

The thing is, when i insert the cd, which is windows 7 home premium 64-bit it shows this error message.

'The version of this file is not compatible with the version of windows you're running. Check your computers system information to see whether you need an x86(32bit) or x64(64 bit) version of the program.'

I think the one that i downloaded is an upgrade only but i did a clean install when i installed it before and its only a 64 bit aswell, this is so hard lol.

i bought my windows 7 from a promo for students for only $50 aud and i chose 64 bit because my computer was runing a vista 64 bit before. But my stupid school cannot support 64-bits so i was planing to dual boot with a 32 bit and a 64 bit windows 7.

What do you guys think i should do?

so all i have with me atm is my windows 7 64-bit and my cd key for it.

If i download windows 7 32-bit will the cd key for the 64-bit work for the 32-bit? or nope?

i tried booting it and it doesnt work lol.

what i might do is, snice i have a cd key for both win 7 and vista, i might reformat this computer using the toshiba recovery disc, install win vista 64 bit, then i can upgrade that to windows 7 64 bit using clean install.

I can download windows vista 32bit and use the cd key that i have in this computer. Do you think that would work?

ok thanks, i'll just download the 32 bit vista, since i want the windows 7 on 64 bit.

So my plan is, download vista 32 bit, reformat this computer to 64 bit vista so i can install win 7 64 bit, then partition and install vista 32bit.

Hope this would work

yes thats what i am planning to do, im vista 32 bit atm, and i cant install win 7, so what im gna do is instal the 64 bit first den do a clean install with the win 7 64-bit so basically it becomes the first partition den i'll install 32 bit vista in the second paritition.

and thats what i did, i went to bios, booted using cd, and it loaded normally like the cd isnt there any ideas? but i guess i'll just stick to my plan if it doesnt work

thanks, 3gig would take a few hours to download, i shall reply here when it has worked properly, which i hope it will lol
