I am new at elementary OS and alternative OS in general. I've just installed elementary in my laptop (Acer Aspire 512, which was extremely slow even it is pretty new) and I am not able to boot from the HDD. If I unplug my USB I get a message telling me that there is no USB unit detected. Only when I plug it back I can boot. Is this normal? Is it not possible to boot directly from the HDD?
Thank you very much!
