From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My disk is encrypted with LUKS and I wanted to make it auto-unlock using TPM.

I can't enter UEFI as I have fastboot enabled.

Could anyone help me please? 🫡

You are going to need to run a rescue system to get this sorted, for example from an USB stick. Usually you can enter UEFI setup by just spamming the button on boot (F2, F12, F10, Del, look up what your system uses). If that doesn't work you can either reset the BIOS settings, using the jumper or button (see manual again, removing the battery is internet lore and almost never required, just use the jumper). Another option is to remove your boot drive, that will prevent fastboot from working, so the next boot will be a regular one.

Depending on your BIOS and with fast boot, you might need to just hold one of the keys while booting instead of spamming it on boot.
