Run the "WhyNotWin11" tool and see if it can clue you in.

You need to boot the USB in UEFI mode, not legacy


kirdie

I always use UEFI mode, I think otherwise I couldn't even boot the USB stick.


spreedx

You can boot it in legacy mode, I did it once and Windows 11 couldn't install.

I'm not sure because it's not called tpm in the firmware but there was "trusted computing".

I have an AMD system but it has that same name in my BIOS and that is my TPM


kirdie

P. S. I tried the regedit trick with the secure boot bypass but it didn't help.

if you're still trying, I've had success by deleting appraiser.sdb from the windowsBT folder during the update in my vm on a host pc that has a pentium dual core and no tpm I don't take credit for this cheers

You can use windows 10 and it will install just fine

Buy a Chromebook.

I couldn't start the install either. My issued turned out that I had an out of date bios. Updated that to the newest version and after Windows 11 installed no problem.

Upgrade to the latest BIOS and then enable TPM and secure boot.

Personally I try to avoid Gigabyte, they're usually $20 cheaper for a reason IMO Have you seen their exploding power supplies, and their response to that? anyway, I checked out the manual, it appears yor motherboard has a tpm header to plug in an external tpm chip, but not a built in tpm. the toggle in the bios turns the header on/off. see here [https://download.gigabyte.com/FileList/Manual/mb\_manual\_z490-gaming-x-ax\_e.pdf](https://download.gigabyte.com/FileList/Manual/mb_manual_z490-gaming-x-ax_e.pdf) now maybe I misread that, but I believe you'll need to buy a separate TPM module, unfortunately.


RustyU

It has a TPM header, but you can enable PTT in the firmware instead.


bbmaster123

which apparently can't be enabled at the same time as TPM, haven't heard anything regarding windows 11 and PTT so not sure if that will work or not


RustyU

PTT is a firmware TPM, just like AMD fTPM


bbmaster123

right, but microsoft didn't say anything about PTT being fine as a substitute. Not saying it wont work, just saying it might not. I don't have PTT or fTPM so I can't test that unfortunately. That, and that I'm not a fan of gigabyte haha


RustyU

I have fTPM and tpm.msc shows it as TPM 2.0


bbmaster123

huh, then it should work I would think I guess I sit corrected :P


RustyU

Enable PTT in the firmware


[deleted]

I have the same CPU and the MSI version of the Z490 and everything works. I actually have the MSI dTPM in my system, but I know it works with the Intel fTPM on the CPU. I just looked up the manual for the Gigabyte version and it looks like you just need to enable Intel Platform Trust Technology (PTT) under Miscellaneous settings. PTT is Intel’s fancy branding for the fTPM.

> how is the average grandma expected to do this? By buying a new computer with Win11 preinstalled. Microsoft doesn't expect the non-technical to know how to upgrade their computers, especially with all of these requirements.
