I have problem with upgrading Windows 10 x64 from Windows 10 x86

Hello. I also wrote a thread, where I asked do my CPU can handle x64, and everything said yes. So I tried to looking for installers, I downloaded one, and with rufus I extracket it on my pendrive, but when I tried to boot from USB in the Windows 10 bios menu or something, it displayed "System doesn't have any USB boot option. Please select other boot option in Boot Manager Menu" then I clicked on "OK" and it appeared:


I don't know how to fix or add that boot option, I tried to looking in the real BIOS menu but there was nothing much I can do.
I also tried with multiple installers and with other pendrives but I got the same everytime.
Someone knows how to fix it? Thanks.

I find it much better in changing from 32-bit to 64-bit on machines that can handle it by starting with a completely clean main drive. 32-bit/x86 can't upgrade to 64-bit/x64 installation, has to be completely redone. I use a bootable CD with a partitioning program to wipe a drive before doing the change. And that has to be done when using a drive previously formatted as MBR in a UEFI or GPT machine.

I don't have CD drive.

And all tutorial video which I saw all was upgrading x64 from x86 is just installing an x64 Windows 10 from USB, nothing special.

The term "Upgrade" is often use to mean that items (e.g., settings, data, apps) are retained in the process.

As such, there is no "Upgrade" from x86 to x64 -- you have to do a clean-install.

Yeah excatly, I want to do a clean-install, and I have everything to it, but I can't boot from USB, because my BIOS is broken or something.

During the initial startup do you see text on the black screen/logo screen about pressing Del, F2, Esc to enter the BIOS Setup? Do you see anything about pressing F12 or other Fx key to choose a boot device, that would be where the USB or CD/DVD is chosen?

I can only enter to my BIOS but there's no usable option which I can use.

I'm curious as to where you are getting these different "installers" and why are you using RUFUS? Why not just use the tool that Microsoft provides to create the USB flash drive for you?

Download Windows 10

Click the Download Tool Now button and run the Media Creation Tool.
Select the option to Create Installation Media for Another PC. Uncheck the box for "Use the recommended options for this PC" and then you can select the language, Windows 10, and either 64 bit, 32 bit or both. Let the Media Creation Tool create the flash drive for you and it will be compatible with both UEFI install and legacy BIOS installs. From the screenshot in your OP, you have a UEFI computer. That means the flash drive must be formatted as FAT32. I'll bet yours are formatted as NTFS.

Using the tool that Microsoft provides has two advantages - you know you are getting a genuine Windows 10 "installer" with nothing modified or added to it, and it creates a universal flash drive that will boot both in UEFI and legacy BIOS computers/modes.

Also, if your computer has both blue and black USB ports, try plugging the flash drive into a black USB port - preferably one that is directly off the motherboard on the back of the computer. Sometimes the blue USB 3.0 ports are not active until Windows loads a driver for them. You need to have the flash drive inserted when you power on the computer.

I am pretty certain your device is a tablet/low end laptop or hybrid, probably with a 32GBmc drive.

The clue is Windows IA32 OS on the EFI bootloaders.

It is quite common for such devices to run as 32Bit even though CPU is 64bit.

Basically the firmware is almost certainly capable of only running 32bit Windows (which has a smaller install footprint).

To run 64bit would require reflashing firmware and putting a 64bit bootloader. This is way beyond capabilities of mere mortals, even if you could source such firmware changes.

As a rule, you only see a usb drive in that menu if a bootable usb drive is plugged in.

I had a issue on my tablet it would not show, and I had to update the bios (32bit of course). Then the usb would show up


This is rather academic though as I am pretty sure you cannot run 64bit any way.

What is your device)?

I tried your option, but I still got the error message while booting, and there wasn't boot from USB option...
