410s w/no hard drive COA 7Pro 32 or 64 bit?

[skeith]

I have a 410s Type 2904-CGU Intel i5 without the hard drive. The COA on the 410s is for Windows 7 Pro. It looks like some 410s machines may have been factory loaded with the 32 bit OS version. I prefer to load 64 bit OS. Is there a way to determine which was originally installed on my 410s? Will my OEM install COA allow me to properly install either the 64 or 32 bit OS, or are the OEM OS COA installs limited to only the bit version originally installed at the factory?

Welcome to the forum.

The COA will allow either 32 or 64 bit.

Recovery disks will install the os and most drivers. If you want them and a 1.8" drive place a WTB post in the marketplace.

The key will work for both x86 and x64. You can punch in the machine type/model into Lenovo's support site and it should tell you if the original install was x86 or x64 unless it was CTO. I think it's unlikely it was x86 from the factory unless the buyer requested it. If you've got Windows on there you can right click my computer and hit properties, and it will show if it's 32 or 64 bit.

When is it possible to switch between 32 bit and 64 bit versions of Microsoft Operating Systems by using recovery media?
