Installing 32-bit Windows 7 on an EFI machine

I'm running Windows 7 Professional 64-bit on an HP Envy 17t-K200 notebook.  I'd like to install Windows 7 32-bit on a different partition, but the setup disc says it can't be done on a system with EFI.  Is there a workaround for this, which will allow both operating systems to boot?

I don't think you can install Windows 32-bit in a 64-bit EFI partition . You CAN install Windows 32-bit in a VMware  Virtual Machine

IF the firmware allows, you may be able switch to BIOS... but then you'll have to reload the 64 bit Windows.  Much better idea is to run the 32 bit version as a VM.

Thank you both.  I am using Windows XP Mode on the 64-bit system, but it lacks some features I require.  When you say I would need to reload the 64-bit Windows system, I have a disk image of that system, with all the applications and configuration settings.  Would I be able to restore that image, and avoid having to re-install everything?

You are better off on my view to use a virtual machine. When you move on from Windows 7 (that day not far off) you can take the machine with you

Probably, but it might be tricky.  And again, your laptop must support switching to BIOS.  What features are you missing that you require?

I'm still seeing if Windows 7 32-bit can be installed.  I converted the hard disc from GPT to MBR, and everything still works.  In the meanwhile, I'd like to know what would happen if I restored a disc image which was made before the conversion to MBR.  Would that preserve the MBR formatting, or revert it to GPT?

As for the feature which Windows XP Mode doesn't support -- I need real time synchronization of data between a 16-bit application running in XP Mode and the same application running on another Windows 7 32-bit machine.

Lee W, MVPTechnology and Business Process AdvisorCommented:
It depends on what you created the image with.

So you need two operating systems to see the same files as identical?  And you can't do this with a network connection?  Have one connect to a shared drive on the other for data?

16-bit can only talk to a 32-bit Machine and that would require SMBv1 to be running.

What about getting a stand-alone 32-bit Computer (used on eBay)

Thank you, but I would appreciate it if we could avoid a tangential discussion about alternative approaches.  I'll post again after trying to install Windows 32-bit.  Meanwhile, if you could answer my question  in comment 42522650, I'd be grateful.

I meant to award an assisted solution, but there is apparently a new system in place, and I wasn't given the opportunity.  I appreciate both Experts, and was able to install the 32-bit Windows 7 by changing the system partition from GPT to MBR and enabling legacy bios.

I am glad you got that sorted out. The world is changing to 64-bit so you do need to get rid of your 16-bit as soon as possible. Yesterday is not too soon.

Once world is 64-bit only, your situation will be hopeless
