I have a new Acer Aspire E5-575 laptop. It has Windows 10 installed on it. I also installed Lubuntu (a form of Linux, specifically a form of Ubuntu) on the hard drive. I had to change the BIOS settings to do this, but I was able to get the PC to then boot off a USB thumbdrive with a Lubuntu live OS on it. And then installed Lubuntu on the hard drive.
But I cannot figure out how to boot into the installed Lubuntu. If I push F12 on boot up (with no thumbdrive Lubuntu live on it in a USB port) I get only one choice, to select Windows Boot Manager and boot into Windows 10. If I do not hit F12 on startup, it just automatically boots into Windows 10.
On the other hand, if I have Lubuntu live on a thumbdrive in a USB, I can live boot into Lubuntu and I can see the installed Windows and Lubuntu partitions on the hard drive. But I cannot boot into the Lubuntu OS on the hard drive. I am hoping that a procedure such as the one here
https://askubuntu.com/questions/627416/acer-aspire-e15-will-not-dual-boot will work. On the other hand there is a recent post on this forum that said it cannot be done.
QUESTION: Can anybody tell me if it is possible to reset the BIOS or UEFI so I can boot into the Lubuntu (Linux) on the hard drive?
Thanks,
Bob
