Laptop booting straight into Windows after Ubuntu installation

gb flag

Title, scoured Google, asked the Odin Project Tech Support and Ask Ubuntu and didn't get a response, questions here and here didn't help, totally at my wits end. There's so much info out there I don't even know what's relevant/helpful information, but here's the gist - I followed the instructions here, from "Installing Ubuntu" down.

It was a nightmare to get it to recognize my free partition on my one and only drive (SSD), but it finally did, I got an "Installation Complete", and then it said I needed to restart to use Ubuntu. I did, and it went straight to Windows. Not only that, but in the BIOS config screen there's no option for Ubuntu at all. It's just like it doesn't exist. I even put my bootable USB back in to access the GRUB (only way I could figure out how to access GRUB, instructions I followed online to hold down Shift while starting up didn't work), and there's not on-disk Ubuntu option there either.

Fast boot is disabled, secure boot is enabled.

Any help is HUGELY appreciated, and I'll provide any information asked for if it's helpful, I just didn't want to overload here with irrelevant stuff.

What version of Ubuntu? What brand/model system? Some like Acer require special settings. Some like many HP need boot order changed in UEFI settings. You did install in UEFI boot mode? Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed.Lets see details, use ppa version with your USB installer (2nd option) or any working install, not Boot-Repair ISO https://help.ubuntu.com/community/Boot-Repair https://sourceforge.net/p/boot-repair/home/Home/

@oldfred I appreciate the response - I actually just found out a couple hours ago that all the issues I'm having is due to Intel Optane Boot Manager.

My new Dell just worked with 22.04. It implemented the Intel® VMD driver which has been in kernel for a while, but I do not think Ubuntu used it until 22.04. So my RAID on system just booted. I forgot to check settings before installing & it just worked. It shows: Kernel modules: vmd, ahci and vmd in use.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
