After carefully reviewing answers to these similar questions:
- "This computer currently has no detected operating systems."- Ubuntu 14.04 install Windows 8.1
- "Install alongside" option missing. How do I install Ubuntu beside Windows using "Something Else"?
- How do I install Ubuntu alongside a pre-installed Windows with UEFI?
I am facing this message while trying to install Ubuntu 23.10 alongside Windows 10 which is already installed: "This computer currently has no detected operating systems. what would you like to do?"
Previously I had Ubuntu 22.04 and there was no such problem when installing the prior versions of Ubuntu. System Specs and Configurations:
- Laptop: Lenovo z50-70
- Intel Virtual Technology: Disabled
- Secure boot: Disabled
- Secure boot status: Disabled
- Boot mode: UEFI
- Fast Boot: Disabled
The status of Windows partitions and those for Ubuntu are healthy.
I made the USB bootable using the Rufus and the Ubuntu iso file was downloaded from the Ubuntu website.
Update
Ubuntu version: Ubuntu 23.10 (Legacy Desktop Installer)
Rufus 4.3.2090, configs:
- Partition Scheme: MBR
- Target system: BIOS or UEFI
- File system: large FAT32 (Default)
- Cluster size: 32 Kilobytes (Default)

, where as if you were installing a Desktop ISO there are two installers selected by the ISO you download and install. You didn't specify which product (Server/Desktop) you are using, and if Desktop which installer you tried (or if you tried both). If 23.10 flavor different installers are used too (with a choice for Budgie like Ubuntu Desktop). Some reformat options of ISO write can cause bootloader to fail to install, but you didn't specify ifrufus

or legacy installed is found in ISO namedhttps://cdimage.ubuntu.com/releases/23.10/release/ubuntu-23.10-desktop-legacy-amd64.iso
(note: legacy in name!) Your last comment contradicts edits to question which imply legacy. After install (if system boots) the results will be identical, but both install differently. – guiverc Dec 17 '23 at 20:48
