Bought a new Acer Aspire ES1-572 with windows 10 pre installed; made a ubuntu 16.04 usb flashdrive and installed ubuntu after a trial next to windows. Worked beautifully. Since I really want to get rid off Bill Gates, after a few days of flawless working, decided to reinstall ubuntu from the fdd and wipe disk in the process. From then on, the laptop will not start up without the fdd as booting device. When on its own, it says: no boot device found. Funny, after installation it said: install succesfull, go on trying ubuntu, or restart from harddrive. Looks like there is something missing.
What do I do?
