How do you boot Kali Linux from a flash drive on a UEFI system

[_defalt]

i was able to scale the following warning:
WARNING: Failed to connect to lvmetad. Falling back to device scanning.

by first disabling lvmetad and restarting it. b4 updating grub could work.


/etc/init.d/lvm2 stop

gedit /etc/lvm/lvm.conf

and then set use_lvmetad = 0
after that use
/etc/init.d/lvm start

I've a question. Did you stop lvm2 of kali live or did you make these changes in mounted /dev/sdb6 because it doesn't matter if you forget to start lvm2 of kali live, after reboot everything is reset but if you make these changes in /dev/sdb5/etc/lvm/lvm.conf it will be permanent. I'm assuming you must have gone to kali live filesystem.

lol...i made the changes in the chroot, therefore its on the already installed kali on sdb6

Can you exactly tell when do you make these changes to lvm.conf? After which command, is it after entering chroot /mnt? Just an off-topic question, i'm curious about this solution.

Now as you are saying that grub is giving you an error Cannot find EFI directory. Reboot kali live and try again.

not really after chroot /mnt, i had typed a couple of commands, b4 that.

Now as you are saying that grub is giving you an error Cannot find EFI directory. Reboot kali live and try again.

I've just done that, no success, at grub-install /dev/sda
i get the message.

Installing for x86_64-efi platform.
Could not prepare Boot variable: No such file or directory
grub-install: error: efibootmgr failed to register the boot entry: Input/output error.

no luck with grub-install /dev/sdb?

I've one more solution. Boot into kali live and mount your EFI partition using mount /dev/sdb2 /mnt/boot/efi. Then remount it for read write access using mount -o remount,rw /dev/sda2 /mnt/boot/efi. Go to /mnt/boot/efi/EFI and delete the folder of kali. Do not touch any other thing. Take the backup of EFI folder before entering into it and erasing kali folder. Then run those list of commands again after reboot.
