I had previously tested this dual boot on an older legacy BIOS PC, and it worked fine. I have a new Dell Precision 3660 with UEFI BIOS, with 2 x 1TB NVMe drives. It came with Windows 11 installed, and I installed Ubuntu on the spare drive and it went fine. From BIOS, when I select Windows bootloader it starts to boot Windows, but just sits with the spinning wheel and never actually boots into Windows.The Windows 11 partition is still there, but I just need to get the bootloader to recognize it.
Here is the link to the pastebin from Boot-Repair.
