Following instructions from

Stuff I did:

  • Change SATA Operation so that Ubuntu can see the SSD
    • Login into Windows 10, and set up Safe Mode: "Change advanced Startup Options" -> "Restart Now" -> "Troubleshoot" > "Advanced options" > "Startup Settings" > "Restart"
    • Boot laptop and press F2 -> BIOS Setup
    • System Configuration -> SATA Operation
    • Change SATA Operation from "RAID On" to "AHCI"
    • Apply and Exit. This will reboot the laptop, and provide several boot options
    • Choose "4. Safe Mode"
    • "Start" -> "Windows System" -> "Control Panel" -> "Device Manager". Check that the "IDE ATA/ATAPI controller" is "Intel(R) 100 Series/C230 Chipset Family SATA AHCI Controller"
    • Reboot normally. This should boot into the regular Window 10
    • If you reboot and go into the BIOS, SATA Operation should still be AHCI

  • Install Ubuntu:
    • boot bootable usb stick (hold F2 during boot, and select it from the boot sequence menu)
    • run `sudo gparted`, and reduce the size of the main windows partition to 173000MB
    • run installer, choose option to install along windows boot

Switching between Nvidia and Intel

Use these commands:

sudo prime-select intel
sudo prime-select nvidia
prime-select query

After switching, you have to reboot. When Intel is selected, it seems to hang on reboot, but can be booted in recovery mode (and immediately leave recovery mode).
