Can't install Linux 2.9.8 hybrid alongside Windows 11.1

I know Windows 11.1 uses a GPT partitioning. Everything I've read indicates that if I used Rufus to make the USB live stick on a GPT partition that I could do a dual boot install. I turned off bitlocker on the Windows files, turned off secure boot, turned off fastboot under the power settings, and shrank the windows partition to give me 50GB for the install. The install asked me for a missing file related to a sound card and didn't recognize my network (wifi). I selected manual partitioning and did not see any of the partitions other than the USB stick. The live version booted and ran fine. Running gparted showed the EFI partition with an error triangle alongside. I suspect this has something to do with GPT but I can't figure out what.
I'm trying to install this on an HP Laptop. Any thoughts?

I went through all the recommended steps on the forum with the exception of clearing the disk of Windows and partitioning the whole disk as MBR and then reinstalling windows.

I've finally got to a stage I never need to boot windows again. But what i've always done is install a second SSD/HDD and instal Linux to it. Then select what drive to boot from using the BIOS boot menu.

I did once have a dual boot laptop using grub but the system got its knickers in a knot and I lost everything so have never wanted to risk it again.

Same here. with dual boot things get complicated when I want to replace one OS and keep the other. My fix has been: one hdd = one os.

Just to be safe, I pull all bootable drives and leave only the one connected, to which I'm installing the OS. This greatly reduces my chance of making mistakes when selecting what installs where. My dual boot mini-pc contains two SSD's.

That said, I can see the case for dual booting on one drive, especially if the machine only has one drive slot. Did you see  wiki.debian.org/DualBoot/Windows  ?
