I got a new computer. This computer works before with a multi boot (ubuntu OS, kali OS and windows OS). I wanted to erase all datas for install only a Kali linux OS (no multi boot, just only Kali).
I installed a kali linux with a usb live. For partitions disk, I manually created :
An EFI partition, a boot partition (ext4, /boot),a swap partition (ext4) and a root partition (ext4, /). Swap and root partition are encrypted.
I haven't any error during the installation, but when I start my laptop, kali does not launch and I have this screen instead :
If I select "kali" or "ubuntu" or "windows" nothing happen. SI, I created a new live usb key with supergrub grub 2 disk (https://www.supergrubdisk.org) and start my computer with this key.
I get this screen :
If I go to "Detect and show boot methods", I get :
And if I select the sixth entry "kali GNU/Linux", the computer start to kali Linux ! this command works !
My question is : how can start on kali automatically without my "super grub2" usb key ?
