Tried several 20.04 installs with different usb sticks using the standard instructions from the Ubuntu website: download the ISO, use Ballena Etcher to flash it to the usb drive, then boot into the USB drive to install Ubuntu.
The first time I used a custom partition, and the second time I selected "install alongside Windows [Recommended]"
Both times didn't work, and afterward there is no boot option to choose between ubuntu and windows; the default Windows bootloader automatically boots to windows. Should I just try an 18.04 dual-boot install, or do a cost-sanity analysis of buying a $300 laptop with ubuntu preinstalled? Changing bios boot setting to legacy
didn't work.
