Help with windows 7 upgrade 32bit version to windows 7 64bit version

I have a Acer 7520 laptop that is compatible for a 64bit version...I have Windows 7 Home Premium now and want to upgrade to Windows 7 Ultimate 64bit version...My question is how do I go about this and what concerns I may have with drivers or any other things I may not be aware of.....Thanks fo any help you can give....Dubld24lo

It is my understanding that to switch from 32bit to 64bit a re-install is required. In other words you cannot upgrade from 32 to 64. I would recommend making sure that your hardware drivers are available in 64bit as well as any software that you use regularly.

You should be fine with Windows 7 64-bit but do perform a clean install and do note the advice from roban, good luck

I basically would like to do the same thing . I have a Core i7 860 /IntelDP55KG/NvidiaGTX275 Box ,running Win7 Ultimate 32bit,w/4GB ram ,And I want to upgrade to 64bit .I have a single WD 1TB HDD . I already have lots of files,Movies,songs ,Game ect, .Will I be able ,to Partition My HDD to install 64bit ,and Keep my 32bit ,and old files ???? without destroying them???? I am regretful that I did not Start with 64bit in the first place. Or will I have to Buy a second HDD ????? Money is quite tight now!!!

You WILL have to do a "clean install" or as Windows 7 calls it; a custom install.

You CAN partition your hard drive, but I would only keep the files, movies and songs. You'll have to re-install your games, applications and other programs.

You can use Partition Wizard to do this from a bootable CD. There is a 30MB ISO CD image file at their website you can download and burn to either a CD-RW or CD-R disc. IT'S FREE!

Partition Wizard Bootable CD allows user to boot computer directly into Partition Wizard to manage partitions without any limitations.

Features including Rebuild MBR, Partition Recovery, Move/Resize Partition, Copy Partition, Create Partition, Delete Partition, Format Partition, Convert File System, Hide/Unhide Partition, Explore Partition and much more.

You can use ImgBurn which is a free IMG burning software or CDBurnerXP which is also free, but has many more features.

Functions of Partition Wizard Bootable CD
Partition Wizard Bootable CD has the same features as of Partition Wizard Home/Business Edition. Features include: Move/Resize Partition, Copy Partition, Create Partition, Delete Partition, Format Partition, Convert File System, Hide/Unhide Partition, Explore Partition, Partition Recovery, Convert Dynamic Disk to Basic Disk, Rebuild MBR and much more.

System requirement
Partition Wizard Bootable CD support 32/64 bit Windows XP, Vista and Windows 7

Version 4.2.2 has solved the technical limitations of bootable CD. Now you can use this new bootable CD image to boot your PC and manage partitions just like Partition Wizard Windows edition.

How to get Partition Wizard Bootable CD
Download Partition Wizard Bootable CD iso file absolutely FREE from http://www.partitionwizard.com/download.html. Burn ISO file onto a CD using any CD/DVD Burner software.


If you can afford another hard drive I would get one, it's more convenient to do it that way plus keeping the OS separate from your valued files. Get a 160GB SATA II hard drive an use is for you OS, or whatever size you can afford.

Thank you very much !!! The only problem I see is That I bought the Game CRYSIS ,via Download from "Steam" I don't mind downloading it again , but I would hate to have to start over ,as I am halfway through it!!! Maybe I can save my game saves??? Or even Burn My Files to a DVD??? To save CRYSIS?

I think I will Just Buy another Hard Drive ,That seems to Be the best way to do this!!!! Thank you Very Much!!!! I really would Love a Velociraptor , But ,A 7200rpm will have to do for Now!!!!

Velociraptors aren't all they're cracked up to be. If I had the money for one of those I would just bite the bullet a little more and get an SSD.

No offense... just my opinion.

If you want true speed you would need to put 2+ SSDs in a RAID configuration, then you will see some performance that would leave Raptors behind

Yes , I forgot about SSD's I think ,once they start to come down in price ,It will be a no Brainer to upgrade to one.
