    Modify the Setup- a04a27f4 - df00-4d42 - b552-39411302113d file but when I pulled replace the following error >
    root @ ubuntu : ~ # cp / home / gustavo / Desktop / Setup- a04a27f4 - df00-4d42 - b552- 39411302113d / sys / firmware / efi / efivars / Setup- a04a27f4 - df00-4d42 - b552-39411302113d
    cp : can not create a regular file ' / sys / firmware / efi / efivars / Setup- a04a27f4 - df00-4d42 - b552-39411302113d ' : Permission denied
    Any ideas

    I could already change the file with another linux distro but does not make me any change in the bios ... check the file to see if the change was made correctly and that was it . I made 3 downgrade the bios and nothing : /

    Thanks very much!!

    I bought an Aspire v5 122p about a week ago and ran into the same problem with no access to the bios virtualization flag. I searched the internet for about three days until I found your post. Just ran through all the steps tonight, powered off then powered on and sure enough, I now can do 64bit virtualization in Virtualbox!! One very importand addition I had to do however, I couldn't save the efivar file, got permission denied. So I ran

    chattr -i Setup-a04a27f4-df00-4d42-b552-39411302113d

    to remove the immutable flag on the file. Then I was able to edit and save the file with ghex. Also, if anyone is having trouble finding ghex, you need to add the universe repository to your ubuntu apt configuration.

    Thanks very much for sharing this, it's still helping out Acer 'virtualization victims' !! :clap:

    Thanks a lot for the guide.

    I have a solution for the two problems

    1. Booting Ubuntu Live CD in UEFI Mode
    Use RUFUS software in windows and burn Ubuntu image with GPT Option (Not MBR)
    Go to BIOS & Change to UEFI Boot, Then Change boot device list and make USB FHD in position 1

    2. Error while replacing Setup-xxxxx file
    To avoid permission errors while copying back Setup-a04a27f4-df00-4d42-b552-39511302113d file, change its properties first using the command

    chattr -i /sys/firmware/efi/fivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    then

    copy modified file using command below

    e.g. mine was at desktop.. Setup-a04a27f4-df00-4d42-b552-39511302113d
    so i typed
    cd Desktop
    cp -f Setup-a04a27f4-df00-4d42-b552-39511302113d /sys/firmware/efi/fivars/Setup-a04a27f4-df00-4d42-b552-39511302113d enter

    Restore files attributes by

    chattr +i /sys/firmware/efi/fivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    Restart & Enjoy

    Hi.
    I'm trying to complete this process on my acer aspire v5 122p-0468. I'm using Linux Mint 20 on a live usb stick.

    Here I've posted the commands I've used leading up to the error. (Note my efi settings were auto mounted on boot)

    1. root@mint:/home/mint# hexdump -C /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d >/home/mint/modded_efi_setup

    2. root@mint:/home/mint# vi /home/mint/modded_efi_setup (Note I used vi to edit the 5th svm bit from 00 to 01 in the 000000f0 section)

    3. root@mint:/home/mint# lsattr /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d
    ----i--------------- /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    4. root@mint:/home/mint# chattr -i /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    5. root@mint:/home/mint# lsattr /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d
    -------------------- /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d

    6. root@mint:/home/mint# cp modded_efi_setup /sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d
    cp: error writing '/sys/firmware/efi/efivars/Setup-a04a27f4-df00-4d42-b552-39511302113d': Invalid argument

    Thanks for any help.
