Hi, this is my first time installing a Linux distro

I chose ElementaryOS6.1 over Windows 11

I have an SSD with an unallocated partition intended to install the second system, however in my frist Boot (from USB) it does not start the installer
instead momentarily the line appears
"[1.302920] nouveau 0000:07:00.0: unknown chipset (b76000a1)"
I can only access a kind of terminal with the title
elementray Next elementary OS tty1
elementary login:
I managed to access by typing "elementary" as user however I have no idea how to proceed

I found similar problems on the web, however these seem from systems that have already booted before
I have no idea where to put my GPU driver in case the solution is a terminal install or if it is possible
to do this during first boot before installation
I would appreciate if someone could enlighten me as to what I am doing wrong

My computer:
Asus B550a (The BIOS is updated to the latest version according to the manufacturer)
R7 5800X
Asus RTX3060 (the latest available driver is installed 526.86)
Direct X12

There is no such thing. There is either unallocated (free) space or a partition. If you have created free space, you should be able to install there. If you have a partition, it will need to be in a Linux filesystem format and I don't know that you can do that from windows. Best to just have unallocated space.

Did you download Elementary from the official site?
Did you verify that the download was not corrupted during the download process by using a checksum verification?
What software did you use to create the usb? Elementary recommends using Etcher. This is all explained at the site at the link below.

Is there any OS now installed (windows)? Is it a UEFI install?

I've run into similar issues in the past. My technically non-proficient way of troubleshooting is to re image the usb. Re download the ISO if a re-image doesn't work. Try a different imaging program (Etcher is my favorite), make sure your bios settings allow you to boot from a USB. I believe you have to turn off secure-boot? I've not installed Elementary OS before, but if it's similar to Ubuntu in its install process it usually does a nice job of guiding you through the process. If you can figure out how to get the installer to run the rest should take care of itself. If you're still having issues, see if you can get Ubuntu or Debian to run an installer. You may have more success burning a Linux iso from within Linux than from Windows. Hopefully some of the more technically advanced members can offer you a better troubleshooting method than I can.

Let us know how you make out.

that's right I have an unallocated space already created
My disk manager says partition style is GUID (GPT)
Download Elementary from the official site and actually use Etcher to create the USB Boot
to verify the integrity of the download run the command

CertUtil -hashfile Downloads\elementaryos-6.1-stable.20211218-rc.iso sha256

Everything seems to be in order
Right now the installed OS is Windows 11 and if it is a UEFI installation

try to boot a USB with ubuntu and it seems the installation proceeds correctly and without errors, I will try to do an installation with a different ISO

There are a number of possible problems so I would suggest you boot the Ubuntu USB and go to the site at the link below to download boot repair. Use the 2nd option described on the site and after downloading it and running it, you will get a link to post here which will provide details on your system which should enable someone here to suggest a possible solution.

When you installed Ubuntu, what happened when you rebooted? Did you get the same error?

Did the original EOS installation include the proprietary NVidia drivers and never work, or did you install a fully working EOS system, then install NVidia's proprietary drivers, after which the GUI would not start? I wonder if 6.1 is new enough to support RTX3060 without any backports installed.
