Finally, with the help of Dell support, I updated the BIOS and everything finally went well. I could upgrade to W11. Thanks to them!
Hi everybody, I'm trying to upgrade my Area-51 R5 from Windows 10 to 11 but I'm currently stucked with the TPM 2.0 issue. The solution given in another post is "Enable "Secure Boot Control" under Boot section - which will then disable "Load Legacy OPROM" and then it will allow you to Enable "Firmware TPM"." My problem is "Secure boot control" is greyed and i can't change it. Any idea? Thanks
