I have Acer Aspire E5-511g.
There were 2 OS on my laptop - Ubuntu 17.04 and Windows 10. After ubuntu update my notebook stops booting.
Why I think troubles are in UEFI?

  1. USB and DVD drives are not more recognized
  2. I can't change UEFI settings (I pressed F2 during POST, then changed, for example, boot orded, pressed F10 to save and Enter to confirm.After reboot bootorder ramains unchanged. Same troubles with all other settings except time and date. They changed fine.)

    Is there a solution and what can I do to unlock UEFI?

    Hello and Welcome on the website of the Windows Friend Acer!

     

    You have to know one important thing,the UEFI insecure boot means that is UNSECURE!

    In this mode anybody can flash your BIOS (mostly under an update procedure - penetrating), or if you use live distros on same machine (of course this is in legacy BIOS mode) the UEFI volume simply writable! Like me:

    But maybe you are lucky and this is only an simple crash.  :-)

     

    Sorry, but I think you can't take out the HDD or SSD or both  (same as the battery as you wrote) and after try a simple restart, because this is the first thing what you have to try before  an BIOS reset (BIOS reset: take out the battery and pushin the BIOS reset pinhole on the underside of the machine and in same time power on the machine - but for me it never worked).

    So than first try an BIOS reset (maybe it will work for you),after change back to legacy BIOS mode after start the machine with an live linux distro (this must has Gparted) after in the linux start Gparted as root,after in Gparted- Device-Create partition table-choose msdos after New partition- choose NTFS, after start your machine with the Windows installer DVD and choose the rapair function and from here choose the terminal and in the terminal:   format c: (slow format minimum two or three times).

     

    Sorry if your BIOS already harmful flashed the only solution is an BIOS update (but only on a cleaned machine-clean HDD,SSD,PCI cards and on others where the harmful codes can hide yet) but I think from the legacy BIOS mode will missing from the new updated BIOSs :-( only will UEFI BIOS mode (incomprehensible!!!).

    If you can't take out the HDD and SDD and restart the machine or make a BIOS reset than you have to call the Acer Service :-(

     

    Good Luck!
