Hi,
I already bought and installed Windows 8.
I have a i7 laptop with 64bit proccessor but somewhat the company decided to pull it out with win7 32 bit OS.
When I upgraded to win8 I wanted to switch to 64bit but didn't find the option for that during the installation proccess.
Can I do it now? switching from 32 to 64 (I understand that I will need to reinstall the windows again, I just don't wanna pay again for that).


Thanks,
Yarden.

Hello Yarden, and welcome to Eight Forums.

To get a 64-bit Windows 8 ISO download, you would need to download it from within a 64-bit Windows. If you do so from a 32-bit Windows, then you get the 32-bit ISO as you already know now. :(

The tutorial below can help show you how to download a new ISO.


Afterwards, the tutorial below can show you how to do a clean install with a Windows 8 upgrade if needed.


Hope this helps, :)
Shawn

Hi Shawn,
Thank you for your reply!
My friend got a Win7 64bit computer, I'll ask him to download the ISO of 64bit for me,
Will he be able to use my 32bit serial key on the 64?
Also, Will it work if my PC already registered to this number?

If not, how can I do it else way?

Thanks,
Yarden

That's not the point. You can download Win8 x64 from any machine, but you wont be able to upgrade from a 32-Bit OS. Download the ISO, burn the DVD and boot from it. Backup your data or simply store it in another partition before install.

If you need to download 32bit Windows 8, download from a 32bit PC.
If you need to download 64bit Windows 8, download from a 64bit PC.

Ops, my mistake !

Surely you can’t do it electronically, but you still can to get the retail version. This package provides both 32-bit and 64-bit media, so you can choose which to use. Of course this is for a clean install !

This procedure will work for BIOS installation (not the only one). One way or another it is covered in our tutorials.

1. Start up to your Windows 8 64-bit upgrade install DVD (or flash drive). Run the Diskpart command using command prompt.
2. Do the first 4 steps here: SSD / HD : Optimize for Windows Reinstallation on the disk on which Windows 8 is to be reinstalled, presumably Disk 0 in your case. Use the clean all command (not clean command) as used in the snips. Don't know why clean all is repeated in step 3; ignore the repetition. The clean all command writes zero to disc and leaves the cleaned drive having only unallocated space. Execution of this command takes considerable time, but leaves nothing on the drive--including no traces of a prior OS--whether it was an OS qualifying for upgrade or Windows 8, itself.
4. Follow the steps in Clean Install - Windows 8.
5. Check out the "Note" in step 8 of the above tutorial. I recommend having the 350 MB System Reserved Partition. At this point, your disk will have only unallocated space having used Diskpart/clean all--which is what you want.
6.Win 8 may not be activated at this point. If not, then activate using the refresh option in Clean Install with Windows 8 Upgrade.
