When I got the laptop it had endless OS on it. I tried to change the OS to Ubuntu 18.04 LTS, and when it asked me what I wanted to do with the drive, I picked the delete everything option (and didn't show the partition manager for some reason).

Then it finished and restarted it then it starts loading as normal but after a few seconds it shows an error message and restarts and it does this forever.

What can I do about this?

    You may need full cold boot. https://askubuntu.com/questions/652966/unable-to-access-bios-menu-after-installing-windows-8/653006#653006 Also if Acer you need in UEFI set a password and enable "trust" on the .efi boot files. Acer Aspire E15 will not dual boot, many details Trust settings in step 35 http://askubuntu.com/questions/627416/acer-aspire-e15-will-not-dual-boot – oldfred Jul 10 '18 at 19:16
  • This looks like a BIOS message, likely due to CMOS battery failure. – Zeiss Ikon Jul 10 '18 at 19:17
  • It's brand new aspire 3 a315-31. – Koppány Kovács Jul 10 '18 at 19:34
  • And the fwsetup opened more options i.stack.imgur.com/VkYpu.jpg – Koppány Kovács Jul 10 '18 at 19:39
  • and where i need to set a password ( supervisor,user,hdd) and how i can enable trust on those .efi files and wich ones. – Koppány Kovács Jul 10 '18 at 19:44
  • Or its easier to try hard reset the drive from the bios? – Koppány Kovács Jul 10 '18 at 19:46
  • Link above starting at step 35 shows all the details on setting supervisor password and drilling down in Acer's UEFI to find .efi boot files to set trust on.

I had the same problem with an Acer Extensa 15 - the link pasted by oldfred indeed contained a solution - I'm repasting it here in case someone lands here in the future:

not sure turn off windows fast start-up necessary
for sure not necessary disable Secure Boot in bios in my case <a lot of advice stress     the importance of this

I try to recap my solving (for computer laptop acer E5-571-57H1)
(after installed xubuntu)

turn on and press F2, bios come up (mine called InsydeH20 setup utility rev. 5.0)
go to page Security
go to "Set Supervisor Password" press ENTER (I set pass "a")
go to "Select an UEFI file as trusted for executing:" press ENTER
a new page appear with listed:
HDD0
HDD0

press ENTER on the first HDD0 and see if a sub list with the name "<EFI>" comes up     (in my case did not show <EFI> but: recycle bin and system volume info)
press ENTER on the second HDD0 and see if a sub list with <EFI> comes up (in my case     showed <EFI> and <boot-sav>)
press ENTER on <EFI>, new list comes
press ENTER on<ubuntu>, new list comes with:
shimx64.efi
grubx64.efi
MokManager.efi

press enter on each one and give them a for you recognizable name (I used     "xubuntushimx64efi", "xubuntugrubx64efi", "xubuntuMokManagerefi")
and press Yes

save and exit

go back in bios f2

go to "Set Supervisor Password" and set pass to nill-blank (you want to eliminate a not necessary password that you could forget...)

go to "boot page" tab
you should find the named shimx64.efi, grubx64.efi, MokManager.efi
bring them up in the priority boot list (above windows if you want ubuntu default system)

go to page main - enable F12 boot menu
save and exit

Not sure if this is exactly your issue, but I ran into the same error when I installed Mint for dual-booting with Windows. My HP laptop had the option in UEFI > Boot options > Advanced to add a Customized Boot. It allows you to enter a path and that's where I added \EFI\ubuntu\shimx64.efi. Then I changed the boot order to have Customized Boot on top and it booted into Grub magically. Woohoo. If you can do something similar, this may just solve the issue for you.

Mainly posting this for anyone who may come across this in the future.
