PC Drivers & Software

I've tried to install Windows 11 two times. The first one went well. I had the OS my computer came with, I didn't change anything on my BIOS settings and I could turn on AMD fTPM successfully in order to install Windows 11. I didn't need to change anything else (Secure Boot, CSM...). After some time, I reverted back to Windows 10 because W11 was full of glitches.

The second time I wanted to install it went wrong. I enabled fTPM as usual, without changing any other setting, and my computer didn't boot anymore. It went into a bootloop, and I had to disable TPM and reinstall Windows 10, since the repair tool said that there were several critical files missing.

Now I want to install W11 again, but I'm worried about my computer going into a bootloop again after enabling TPM (or even worse, bricking the mobo/BIOS).

These are my specs:

Gigabyte B450M no wifi (mobo)

ASUS TUF Gaming GeForce GTX 1660 Super OC

AMD Ryzen 5 Pro 4650G

Some Gigabyte RAM (I can't remember the model)

Kingston A400 480GB SSD

And this is my current config iirc:

Partition style: GPT

BIOS mode: UEFI

CSM support: Enabled

AMD fTPM: Disabled

Do you guys know which options should I enable or disable to be able to boot my PC as usual and fresh install Windows 11? If y'all need more info lmk, thank you in advance

Hi @Vxlzy12,

I suggest you clear CMOS before installing Windows 11 (or Windows 10).  Users have reported that this worked for them after a fTPM error during boot.

If this doesn't work, I'd try to clear CMOS again then disable fTPM before installing Windows.  Afterwards go back to BIOS and enable fTPM.

Also, check that your firmware for CPU (AGESA 1.0.0.7c or newer), motherboard and chipset are updated.  fTPM might be residing in the chipset.  fTPM should be v2.0 but it almost certainly is on your platform.
