Converting Windows 7 32bit to Windows7 64 Bit

I upgraded from Vista to W7 some 4 months ago and have the Home Premium Upgrade package from Vista to Windows 7.


I cannot see a way of now moving from 32bit to 64 bit as the 64 bit disk won't work.

I do feel stupid about this but surely, there must be a way without buying an upgrade from W7 32 to W7 64.

Can you point me in the right direction please. I know it has to be a clean install and have backed up already.

There is no 'updrade' from 32 bit to 64 bit. Only a clean install would do it. Good luck.

Many thanks for your speedy response. I Understood that I needed a clean instal. My question is why the 64 bit disk I have will not allow me to do it.

I am hoping that I will not have to buy yet another disc from Microsoft as the Vista upgrade would have allowed me to go straight to 64 Bit.

Is there any Online software that I can install and then use my legitimate licence key to set it running.

many thanks

A couple of questions...

Did you buy the full retail Win7 home premium? or the upgrade version from Vista?

You say the the 64 bit disk won't work, do you get an error? what does it say?

Also, can you post your computer specs?

I am sure you will get the answers here, as this is by far the best Win 7 forum there is. And welcome to the forum

Agreed.

Hum... A member had a similar problem not long ago. It was because the HD wasn't set as RAID, or something else to do with the HD. Will try to remember it.

Kalario, you can do a clean install using an upgrade DVD. That's what I did, and there aren't any problems with that.

thanks for the clarification...

In order to do a clean or "custom" install, do the following:

1. Set the DVD drive to be the first boot device in the motherboard's BIOS.
2. Reboot with the x64 install DVD in the DVD drive, when a prompt appears that says: "Press Any Key To Boot From CD/DVD drive." Do that within 4-5 seconds.
3. The install should begin with a Windows 7 Install screen and files loading.
4. When you get to the screen that shows the hard drive and any partitions, delete all partitions and create new ones. Have one at least 48-64GB in size to install the OS to and the remainder of the hard drive as a separate partition.

You should be good to go now! Follow the prompts on the rest of the install and you'll have Windows 7 x64 version.

Many thanks indeed. The transfer to 64 bit worked perfectly.

HOWEVER, I am left with virtually no disk space.

I do have 3 huge folders marked as.OLD and I presume it is safe to delete these.

Can you confirm that many/most/all files marked as .old are safe to delete.

A pleaseure to have found you and many thanks for your very speedy response.

Hi gch - Welcome to w7forums

Yes if its marked old, you can safely delete it.

I can't de;lete abot 12 gb of files and their folders because of this message. I've eread up about it and haven't yet found a nice and easy work around.

Does such a widget/utility exist please.

Don't you just love the clever boys and girls at Microsoft.
