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).
