Comment 40 for bug 1886148

The boot performance of the Ubuntu Groovy iso file on my computers are the same with today's daily iso file,

#perms size date time file-name
-rw------- 2,6G 2020-07-10 08:27 "groovy-desktop-amd64.iso"

as with yesterday's iso file. At least, I could not see any difference. Most of my computers boot from a USB drive when cloned, but there are still problems with the Lenovo V130.

This Lenovo computer is set to boot in UEFI mode with secure boot.

- The problem is that it cannot boot from a USB drive *cloned* from the current Ubuntu Groovy iso file dated 2020-07-10 08:27. Instead it skips to the internal drive and its grub menu (even when I select the USB drive from a temporary menu). This is the same problem as with the previous daily iso file.

- It works as intended when mkusb uses usb-pack-efi to create a persistent live drive.
