Windows 7 - 32/64 bit

Hi all,

At the beginning of this year I bought Windows 7 for my computer. In the box, there is discs for 32 bit and 64 bit. I installed the standard 32 bit and that was that. Now I want 64bit, but I need to keep 32 bit.

Is it possible to install the 64 bit version as a secondary OS like Linux?
Would I need to install an extra copy of Photoshop CS4 for 64bit?

My computer CAN do 64 bit.
I MUST keep 32 bit.
I know I need to backup prior - I have an external HDD.
I want to keep both the OSs on the same HDD.
I don't really want to partion the drives - if so I want to keep the partion as small as possible.

Cheers!
Will

Why do you want 64bit....???

What your contemplating is likely to lead to complications, Possible instability and general mayhem......!!!

Sure you can dual boot OS on the same computer, But its best avoided for the sake of reliability .

Generally dual boot is 2 different OS, Not the same version with bit variations, You might also find that you will encounter " Activation " issues with Microsoft.....Sad

Personly Your best option would be a second computer running the 64bit version, Far less hassle all round.....Smile

Agree with you camera cat. Wonder what the reason is and does the processor need to be a 64bit computer too?

Thanks for your advice - I suppose it isn't worth the hassle.

I see no reason why it would not work. Installing different OS's or different versions of the same OS makes no difference. Setting up a dual boot computer means that the two versions would be working from different partitions (This is the normal Linux set-up).

Another way to achieve the same thing (assuming you are using a desktop) would be to buy two HDD caddies (that would cost about 40, much cheaper than a second computer). One version would be on each HDD. You close down, swap caddies and start up in the other version. I did this with Linux and Windows XP for about six months before finally switching to all Linux working.

I installed Win 7 64 bit Home Premium nearly a year ago and have yet to find a 32 bit program or app that does not run perfectly.

You might consider installing 64 bit on a spare disk drive and trialling it on its own. Honestly, given the present info you've supplied, I see no reason to use a dual boot.

There will be no problem running the 64bit OS from a separate partition either on the same drive or another.

There are numerous reasons to be running 64bit now and no "drawbacks" - one that comes to the forefront of my mind is that UEFI is supported natively under 64bit windows and its bigger server editions.

Whereas 32 bit requires UEFI mainboards with a special BIOS compatibility layer... This ultimately means more expense. e.g. you will be paying more for a motherboard that 'allows' 32 bit windows in the near future.

Why?

You will need another partition. Also, you won't be able to install both the 32 and 64 bit versions as you have used your product key for the 32 bit one. If you want to use that key for the 64 bit version you will have to get rid of the 32 bit version.

Again, what requires you to need the 32 bit version?

i am running 64 bit and everything runs using 32 bit settings fine.

Yeah, my question too about why the need to keep 32bit...is it old software you have? 64 bit might be aboe to handle it in it's compatibility mode and mlewis is right about the licence issue as far as I know.
