Unable to boot ES1-523 laptop in UEFI mode after BIOS update 1.02

Hello,

I have an Acer ES1-523 laptop running Windows 10 Enterprise version 1803 build #17134.286. My serial number is **********************, SNID ***********.

I was checking the Acer support site for updated drivers and BIOS updates and found that BIOS_Acer_1.02_A_A was available. I installed it, and when the system rebooted, an icon saying No Bootable Device pops up right after the Acer logo is displayed on screen and the system does not boot.

I entered the BIOS and the BIOS version number has now changed to 1.02, and my SSD is indeed shown as the first boot device. I changed the boot mode from UEFI to Legacy, and now it boots, but quite slowly.

Please help me restore the ability to boot my laptop in UEFI mode. I find it completely ridiculous that I updated my system using a file Acer provided and now it won't boot properly. \
This can't be right.

Regards,

TK

    Yes, your disk is in mbr format! If you want to install in uefi mode, this file shows you how to do it! However I think there is no need since your notebook is working perfectly!

    Ideally, whenever you update the bios, you select the load setup defaults option and then save on exit, so that any configuration or bug from the previous version is fixed!
    Try this!
    Did your ssd, before updating the bios, be configured to start in uefi or legacy mode?
    But first, try the tip I gave you above!

    I don't follow. When I ran the BIOS uptate .exe, it rebooted the system and started a program in a pre-boot environment. There was no option to configure anything, or load setup defaults...

    Do you mean I should reboot the system, load setup defaults and try to boot with default BIOS settings?

    Yes! On here: 

    And press f10 to save on exit!
    Then you should check if windows boot manager comes first and uefi mode is selected!

    Tried this, the Windows 12 Boot manager doesn't show up in the boot menu.
    I can boot in legacy but not in UEFI

    What I recommend now is that you back up your files! Then enter the bios again and select the uefi mode and activate the d2drecovery function. Then press f10 to save on exit and immediately press alt + f10 to start installing windows from the recovery partition of Acer!

    LOL recovery partition.... My friend, the original HDD is long gone. I'm running Windows 10 Enterprise and there's no recovery partition.....
  • You can try to update bios to version 1.04 to see if it solves the problem! However it is a very risky procedure!
    What I find strange is that a bios update does not change the gpt (uefi) file system to mbr (legacy) automatically! This is done through the command prompt!
    What I recommend is that you back up the files and reinstall windows 10 by converting ssd into the windows installation by pressing shift + f10 and typing these commands to convert to gpt and work in uefi mode:

    Thank you for your replies, and having considered the risk and disruption to my work I think I'd better leave it as it is for now. The system is stable. Not having UEFI enabled doesn't really impact my day to day use.
  • You made the best decision! However I would like you to tap a photo of the command prompt to find out if the hd is in the mbr or gpt! Format:

    If the asterisk appears, it means that the hd is in gpt format, which will be strange, since this format only works in uefi mode! If no asterisks appear, then the hd is in the mbr format!
