Kali dual boot with Windows 11 (same ssd) - grub doesn't detect Windows OS

Hello everyone
I have a Lenovo ThinkPad laptop and I recently installed Kali on the same SSD as Windows11. During the installation of Grub, it failed to recognize the Windows OS, and I installed Grub on the same disk as it prompted.
I can log in to either OS when I change the boot order from BIOS but I would like to boot into Kali and use the Grub menu to select an OS.

From Windows11:
I can verify via the System Information app that the BIOS Mode is UEFI

From Kali:
I used a command I found in Debian documentation to check that the computer booted in EFI mode:


[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"
Legacy boot on HDD

Also,
bootctl
Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.
System:
Not booted with EFI

In the BIOS Menu, in Boot tab I have these:

UEFI/Legacy Boot [Both]
- UEFI\Legacy Boot Priority [Legacy First]
- CSM Support [Yes]

Lastly,
Fast Boot is disabled in the BIOS menu.

I hope these info will help you understand the problem I am dealing with.
If you need any other relevant info please let me know.
Thank you

I have the same problem
I installed kali 2021 and it was working but when i update it this keeps happening i did remove kali and re-install it but same problem happened

I had the same issue.
In short - there is a way to force GRUB to detect other operating systems.

Code:

---

$ sudo os-probe
$ sudo update-grub
$ sudo reboot now

---

There are few things to consider, the most important of which is the UEFI Boot of the BIOS.
I did have a KALI Linux installed as a solo operating system on this laptop (HP Pro Book 450 G7). I installed a new SSD with a Windows 11 and the Kali Grub did not detect it.
The reason was, that I did not have EFI partition on my Kali Linux installation.
I had to create that, it is just an empty partition about 100 MB size. Then make sure during installation KALI will use it as an EFI partition. That should be your boot-able drive.
In my case I have 1. NVMe2 drive with Linux and 1 SSD with Windows 11.
Your case may be different if you have only a single drive and separate partitions for your Linux and Windows OS. In such case you need only 1 EFI partition (one per physical drive).

I hope this information help you!

Kind regards!
