LinuxQuestions.org - [SOLVED] Getting Acer ES1-132-C2JZ to boot xubuntu from HDD using rEFInd (and not just from USB)

Hi guys,

My tiny new laptop is making me go insane. After fixing lots of smaller problems I've finally managed to get xubuntu installed. However, it won't boot from HDD (gives "No bootable devices" screen). So far I've only managed to boot into my rEFInd usb stick and launch xubuntu (from vmlinuz-4.10.0.40-generic I think?) from there. Please tell me if the following looks correct:

df /boot/efi

Code:

Filesystem: /dev/mcblk0p1 

Mounted on /boot/efi

If I sudo thunar I can see File System, Filesystem root and efi. Clicking efi puts me in /boot/efi.

I've tried installing rEFInd's boot manager here in several ways. First by running the refind-install script, which installs to /boot/efi/EFI/refind. I have no idea whether or not that's correct and should already run or not. Does that path look right? After running this script and running the refind-mkdefault script, efibootmgr prints:

Code:

BootCurrent: 0000

Timeout: 0 seconds

BootOrder: 0001,2001,2002,2003

Boot0000*: USB HDD: SanDisk

Boot0001*: rEFInd Boot Manager

Boot2001*: EFI USB Device

Boot2002*: EFI DVD/CDROM

Boot2003*: EFI Network

To my knowledge, this should be fine. But if I restart my laptop, the bootorder no longer contains 0001. Safeboot is turned off. I'm not sure what else to do. I also don't know if I've done things properly so far so it's hard to know for sure what the problem is. I've found several other issues that may or may not be part of the problem. Some people state here that a similar (but not exactly the same) acer laptop has hardcoded uefi paths, so I should possibly install a boot manager there instead of where I installed it, in some way (the post by spektro37):

Another potential issue is that, although I have the newest bios (1.15), there is no option to set trusted .efi files in the bios. I don't know if that's what's causing my NVRAM boot order to reset. Can I trick my bios into accepting the refind_x64.efi file somehow?

Here's efibootmgr -v output if that helps:
