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 : /
I could .... XD error was that mine was different file name was Setup- a04a27f4 - df00-4d42 - b552-39 "5" 11302113d not " 4"
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' !!
Sir, i have problem the last step. Copying the hex dump from terminal to ghex and save it to the bios. Maybe show in video... thank you. Now i using debian 9.0 to
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.
