You received an executable named spXXXXX.exe during the download from HP. I tested it with a generic search term and downloaded the corresponding storage driver. After extraction, you found several folders including .cat and .inf files. The question is whether this setup allows booting into Ubuntu or using a live USB, and if so, how to verify the disk type (GPT vs MBR) before proceeding.
The file matches what you described for your HP Pavilion x360 Convertible 14-dy0166TU. I'll test it with a live USB, but I suspect Windows might not read the Master Boot Record properly. There could be a reason it doesn’t work in this scenario.
The dchu_* directories must include the .inf files. Windows can work with disks that have an MBR, but it needs the legacy mode (CSM) activated in BIOS to boot. I believe Windows 11 doesn’t allow booting from an MBR at all.
You can verify the disk type in Ubuntu by using commands like `lsblk` or `fdisk -l`. Windows DiskPart provides similar functionality, but some drivers might be missing on Ubuntu. If it doesn’t appear, check the kernel modules or install necessary packages.
