I have a Windows 11 PC and tried to install Ubuntu 22.04 LTS on it. Everything went fine during the install, apparently. When the PC rebooted without the install media, Windows 11 brought up a light blue screen and said that it had failed to start and my PC needed to be repaired. I allowed W11 to do the repairs since I can't lose the work I have on the W11 side.
I'd like to have a dual boot PC but have to keep my Windows side. How do I do this?

Chances are you destroyed the EFI boot partition completely when you installed Ubuntu. (Formatted completely, installed, when asked destroy the partition clicked "yes".) Officially, there is no Windows 11 now. You can check it with fdisk -l /dev/sda (replace sda with whatever you drive is... nvme0n01 or whatever), but it's probably not there.
Normally, you'd have an EFI partition, a Windows Recovery Partition, the ACTUAL windows partition, and then whatever you set up for Ubuntu. (Usually one filesystem with the type "Linux filesystem")
