Am a total newbie, so apologies if this is a stupid question, but I've just installed Ubuntu 18.04.3 LTS via a live USB and cannot get it to boot from the hard drive. If the USB isn't in, it won't work. I don't remember selection any target partition, so I think it must have been automatic.
I can see that the files are installed on my hard drive, but the hard drive shows up not a hard drive but as a 32 GB SD card. I'm presuming this is why it's not loading up from there. I've tried running boot repair, but this didn't fix the problem.
For background info, the laptop previously had Windows 10 on it, which I erased to replace with Ubuntu. Before doing that, it had been set to load all new programmes and apps on to an SD card, since Windows was taking up so much hard drive space. Could that be the source of the problem?
Update: I found this thread which seems to address a similar problem to mine (I have an Acer Aspire ES1 132) and followed the first half of the instructions (to set password and enable secure bbot). However, after I reinstalled from USB and restarted, I could no longer boot from the same USB. Now I only get an error message that \EFI\BOOTVmmx64.efi can't be found and MokManager has failed to start and can't be found.
Does this sound like a problem with the USB? Or have I inadvertently done something wrong in UEFI?
I'm going to burn a new live USB today and try again. Presuming this works and I can get the computer to boot from the USB again, how do you think I can fix the problem of getting Ubuntu to install on the hard drive?
Thanks in advance..
