    ( 0) Pre-shrink Windows partition to desired unallocated space for Linux installation. Shrink it a lot if you want
    ( 1) Make bootable GPT/FAT32(default) stick from the Linux installation iso with Rufus, a freeware download.
    ( 2) Set BIOS supervisor password(SECURITY), disable secure boot(BOOT)& enable F12 Windows boot mgr (MAIN). Save BIOS settings & exit. May not be needed with some Linux installations like Mint.
    ( 3) Shutdown & insert bootable Linux stick
    ( 4) Turn back on while immediately tapping F12. Select Linux stick to run.
    ( 5) Preferrably select a default Linux install option
    ( 6) Follow on-screen instructions to install alongside Windows.
    ( 7) Let Linux automatically set & resize partitions for Linux & its swap. Adjust for more or less space only if absolutely necessary.
    ( 8) Shutdown & remove Linux stick.
    ( 9) Turn back on while tapping F2.
    (10) Re-enable secure boot(BOOT) & select UEFI file as trusted(MAIN). Select HDD0, SSD0 or eMMC0, then <EFI>, then <ubuntu>, then grubx64.efi the UEFI file. Enter grubx64.efi in the space provided if selecting it doesn't automatically enter it. Save BIOS setting and exit.
    (11) Boot into Windows. Then shutdown again.
    (12) Turn back on while tapping F12.
    (13) If desired, put grubx64.efi ahead of Windows boot manager in UEFI bootstrapper

    Hello, sorry for reviving the thread.
    I hope family and friends are fine, and wish happy Xmas days!

    I have a Acer aspire E 15 (E5-576-76j8).
    I do not manage to get a UEFI boot to work. I have Ubuntu 20.04 installed. The PC came with Windows. Ubuntu used to boot fine (I think from UEFI, though I am not sure. Its /etc/fstab mentions a /boot/efi partition.).

    Context: when Ubuntu was still booting fine, I ran a program called boot-repair (I wanted access to my Windows partition, which I could never get as of now), and since then, I cannot find the bootloader anymore. Originally, it landed in a command prompt version of grub (ubuntu´s bootloader), and now, it stops even reaching any bootloader.

    Symptom: It seems to me like a UEFI problem. In the BIOS, I actually don't see my drive in the boot options, but rather a blue "rectangle" (it looks a bit like a barcode). I can also see the live USB medium when I'm trying to boot from there.

    Question: I'd like to be able to boot into my ubuntu again. I currently don't care for Windows. How to do that? This could be linked to Acer, as same setup on Toshiba with same hardware specs works fine.

    Thanks a lot for your help!

    It is best for you to start a new thread on your issue. At initial glance of your EFI partition, you have way too many remnants of other Linux distribution bootloaders that you have installed from time to time. Some of them appear to be in the wrong subdirectories. I'm not sure which ones the BIOS consider trusted right now, Maybe none of them. Boot-repair will only work on a valid Linux partition, not on the Microsoft partition. Jack E/NJ

    Hi Jack,
    I've tried all your suggestions (aiming to get dual boot Win 10 with bitlocker enabled working with Ubuntu 18 on Acer Aspire 3 with single HDD) but it looks like the HDD is not being recognised correctly. When I installed Ubuntu, I had to close the lid and open it again before then going back to the previous screen during the installation process and continuing to the partition selection screen before it would show any partitions. My set aside disk area was then visible as /dev/sdb5 and I was able to install Ubuntu but it seems like it's not picking up on the partition when I try and boot into it (invalid signature for kernel when secure boot enabled, or gave up waiting for root file system if secure boot disabled).
    Cheers
    Andy
