Windows 10: Meeting the Free Upgrade Deadline

In post #10 I mentioned that it was 64-bit. I don't have a copy of 32-bit Win7.
The Celeron 336 is a full 64-bit CPU.

 

If Windows 10 is so all-fired great, why does it tell me that my CPU doesn't support it when it quite obviously does (or it's giving me a false error message to mask something else).

 

I have some difficulties to understand you. You complain that nobody wants to help you, when actually you have already been offered a valid workaround.

With a bit spontaneity you had already found Windows 10 specifications and requirements and read that your issue only involves 64 bit Windows, support for PrefetchW and LAHF/SAHF is not required if you install 32 bit Windows.

Is you being right and Windows setup being wrong about support for PrefetchW and LAHF/SAHF so important to you that you rather miss the free upgrade than get it done by installing 32 bit Windows now and when it's activated, start looking for solution for your issue? You have then all time in the world to clean install 64 bit, your PC being already digitally activated.

I would install 32-bit....about 360 days ago, though.

 

It has nothing to do with "being right or wrong". I specifically stated that I had a copy of 64-bit Win10 and I was looking for a way to install (upgrade the Win 7 32-bit) if I could. So I will miss my chance to upgrade this "junk PC"...big deal.
My point was that I getting conflicting information about the eligibility of this PC to run Win10 64-bit...that's all I had. No big loss. I thought maybe someone on this excellent forum might have some insight.

 

I already installed Win10 64 bit on my main PC (listed under My System Specs). How could I install Win10 32-bit 360 days ago if I just "found" this PC in a garage sale?

 

No, you did not.

You said that you were trying to install the 64 bit version of Windows 10. I might have assumed that you were installing it as an upgrade over Win 7 X64, since you couldn't install it over X86. I admit that I forget what sort of message you'd have gotten if you tried to upgrade Win 7 X86 to Win 10 X64.

I did a little checking. As far as I could find, the Celeron D336 is supposed to support all of the extensions required for Win 10 X64. If the Win 10 installer isn't at fault, it could be that the PC's motherboard would require a BIOS update to expose all of the features of the Celeron. As you haven't told us what motherboard the machine has, it's hard to help you locate a newer BIOS (if one exists).

Sorry that you're running out of time on this. I doubt that the value of the PC would justify a new Win 10 license purchase.

 

Valid reason, I apologize.

 

I considered that. There was a BIOS update for the motherboard (Gigabyte GA-8S661FXM-775) named F4 - Update CPU Microcode. The problem was that I couldn't get the PC to see the floppy drive to write the update to (and then read from).

No biggie.

Thanks for all your help. I learned something at least.

 

I wonder whether the board's SIS chipset has some limitations that might not be present in an Intel board.

Moot now, I suppose.

Too bad that you ran out of time.

 

You are saying that I could upgrade my copy of 64-bit Windows 7 to 32-bit Windows 10?

 

Well I took one more kick at the can to try and upgrade to 64-bit Windows 10 over the weekend. I managed to copy the BIOS upgrade to floppy using DOS commands (ah, good ol' DOS) and upgrade the MB to F4 (for those of you who are curious about the Gigabyte GA-8S661FXM-775 MB. I still got the same error messages about LAHF and PrefetchW.

 

You cannot upgrade any windows os from 32 bit to 64 bit- you would have to reinstall from scratch.
.

 

As I said, I'm trying to go from 64-bit to 32-bit.

 

To put it in other words, changing from 32-bit to 64-bit or 64-bit to 32-bit requires a clean install, wipe the HDD and start from scratch. There is no upgrade from one bitness to another. Same applies to the myriad versions of Linux. Mac OS X is a bit different, I had the 32-bit version of Snow Leopard and was able to upgrade to Mountain Lion then change it to the 64-bit version without having to do a clean install.
