I have two drives, both 500 GB NVMe. One is the Windows drive, which I partitioned to install Ubuntu. I followed this video to do so. I am giving what information I feel is important, please ask me to add more information.
Linux boots OK, but my computer is unable to boot Windows. There is no specific error code at a blue screen, just a simple message that Windows boot drive is not accessible. In the attached image is what I am able to see from Windows.
[enter image description here][1]
I have also run the Boot-Repair tool on Ubuntu. Do I share it here (yes)?
I was suggested to post this question here from Ask Ubuntu.
EDIT: Adding the Ubuntu boot-repair output.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p7,
using the following options: nvme0n1p1/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 The OS now in use - Ubuntu 24.04.1 LTS entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !
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****grub****.efi (**** will be updated in the final message)
