I followed this link: Can't boot into Ubuntu in Windows 10 / Ubuntu dual boot
Specifically this step: Converting Ubuntu into UEFI mode. This was because I believed that ubuntu was in BIOS mode, and I knew that windows install was in UEFI mode because I had reinstalled the BIOS for my motherboard before installing Windows.
Following the step ran without issue, I was asked to copy the commands into terminal and agree to uninstalling GRUB. However it did not fix the problem. After the first attempt of boot-repair using the Converting Ubuntu into UEFI mode step, I got the logs before my second attempt of using boot-repair: https://paste.ubuntu.com/p/hQM3shyktn/

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of
nvme0n1p2,
using the following options: nvme0n1p3/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 24.04 LTS entry (nvme0n1p3/efi/**/shim.efi (** will be updated in the final message) file) !
The boot files of [nvme0n1p3 (end>100GB)] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a ESP partition (FAT32, 100MB~250MB, start of the disk, boot flag). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot/efi partition:] option of [Boot Repair].If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI**\shim.efi (** will be updated in the final message)
All attempts at using the boot-repair in default mode or repeating the Convert Ubuntu into UEFI mode resulted in an error during boot repair.

I think I messed up the boot-repair and I might not be able to salvage the ubuntu part of the dual boot.
Edit:
- I have retried reflashing my usb but error persists.
- And assuming that Ubuntu partition is unsalvageable, if I just delete the parition and follow the install Ubuntu after Windows 11 method, would the dual boot still work?
