Problem Description: Unable to install Ubuntu alongside Windows 11. When I select “Something Else” (manual installation) in the installer, my NVMe SSD is detected but shows as 0 Bytes in size. This prevents me from creating partitions or proceeding with installation.
Relevant System Information:
Device: Asus Zenbook duo UX481F
Windows Version: Windows 11 Home 64-bit (Version 24H2 (0S Build 26100.4946))
Processor: Intel(R) Core™ i5-10210U CPU @ 1.60GHz (2.11 GHz)
RAM: 8.00 GB
Storage: NVMe SSD
Partition scheme: GPT
BIOS/UEFI: UEFI mode, Secure Boot disabled
SATA/NVMe mode: AHCI (RAID/Intel RST disabled)
NVMe drive detected normally in BIOS and works fine in Windows
BitLocker encryption disabled
Fast Startup and hibernation disabled (powercfg /h off)
Screenshots or Error Messages:
NVMe drive listed as /dev/nvme0n1 in the installer but showing 0 Bytes.
You haven’t specifically stated so are you attempting to install Ubuntu to the same physical drive on which you have Windows? If you are attempting to install on the same drive as windows, did you use Windows Disk Management or similar tool to create free space on the drive to use for Ubuntu?
What stands out for me in your image output is 'disk /dev/nvme0n1 does not have correct partition table or cannot be read '. You have verified that you have a GPT partition table, correct? Any interesting output with sudo gdisk /dev/nvme0n1
Found the site below with a brief online search which discusses the problem/bug but the resolution for that person was to create a new partition table which would likely destroy all data.
