Hi, I've faced the same problem. UEFI basically decides which drive gets the OS first—here, the Windows drive has its own UEFI bootloader. Even if you choose Ubuntu for another drive, the bootloader still writes to the existing one. To fix this, disable Secure Boot, enable Legacy + UEFI, and turn on CSM support in Windows settings. After that, reinstall Ubuntu on the other drive, but when you boot the Ubuntu medium make sure it doesn't start with an indicator showing it's UEFI, since most bootable media usually show Bios/Legacy or UEFI clearly in the boot menu.
Checks the UCSI ACPI USBC000:00: PPM init failure code (-110). It seems to be the only issue, but as long as it boots and runs smoothly, I’m confident it’s working properly. No need to explore other fixes if this is resolved.
Kool_Aid_MAn, I haven’t run into that problem before. The challenge lies in switching between operating systems after booting; you’ll need to pick your boot device for Linux or the UEFI bootloader for Windows to reach your desired OS if it isn’t the default. No easy boot menu screen. It functions well on my setup with EndeavorOS installed through a legacy BIOS on an 860 Evo, while Windows runs on an HP S600 using UEFI. However, because they’re different boot types (UEFI vs BIOS) and EndeavorOS is my main boot choice, I always have to press the boot menu key after restarting or shutting down to enter Windows. I have a comparable configuration on another machine with Fedora 33 BIOS and Windows 10 UEFI, and it hasn’t caused any issues.
I would start by taking out the SSD with Windows, then replace it with a Linux SSD. After that, install Linux but place GRUB on the boot partition instead of the MBR. Remove the Linux SSD and insert the Windows SSD to test the boot process. Keep the machine running even if it doesn’t boot properly. Use EasyBCD to install the Linux SSD and set up dual-boot as needed. See if it works.
Can you start using the Live USB? Yes, I’d recommend a corrupted installation and retry. If not, Ubuntu might be missing the necessary drivers, so consider switching to another distribution like PopOS to avoid troubleshooting.
