    Attempted Ubuntu-Windows Dual Boot. Now No Operating System Found

    Hi,

    I attempted to dual boot linux and windows on a brand new HP Spectre x360. I followed online instructions, created a new partition in windows, live installed from USB...all that good stuff. Everything seemed to be working well, I finished the ubuntu install and restarted which booted me directly into windows. Using some more online guides, I attempted to fix this by running the following command:
    Code:
    bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
    After running that command, I restarted and am now faced with "no operating system found" anytime I boot the computer. I've looked through various forums and tried a few things from a live usb install, but had no luck. At this point I'm in need of help as I'd rather not mess something up and create even more problems (like wiping windows if I haven't already).

    Two things I've done since that point are:
    1. Removed ubuntu from the boot order using efibootmgr. I now realize that probably didn't help but it currently looks like:
    Code:
    ubuntu@ubuntu:~$ efibootmgr
    BootCurrent: 0003
    Timeout: 0 seconds
    BootOrder: 0001,0002,0003
    Boot0001* Windows Boot Manager
    Boot0002* Internal Hard Disk
    Boot0003* USB Drive (UEFI) -  USB DISK 2.0 PMAP
    2. Attempted to use boot-repair. Unfortunately boot-repair didn't have any recommended instructions but I do have the diagnostic paste-bin - http://paste.ubuntu.com/p/ZZh2jwd69b/

    Any help is greatly appreciated, thanks.

    It looks like you still have drives set to RAID/Intel RST, not AHCI.
    But for Windows to work you have to install the AHCI drivers first.
    And in Windows make sure fast start up is off.

    A lot of HP 360 threads.

    Thanks for the links. The top one did the trick. I had to disable optane from bios
