I have a laptop Lenovo Thinkpad x13 gen2 from 2021
I have 3 partitions, 1 with Windows 10. I want to install Ubuntu deleting only this partition and keeping the other two.
In order to do so I make a USB flash boot device with Rufus and ubuntu-20.04.4-desktop-amd64.iso
I enter BIOS setup and make save boot off and when I select the boot device, booting from my USB drive this is what happens:
A Grub console shows up, and then when I write boot guess what:
error: you need to load the kernel first.
Where is the way to proceed? I really need to install Ubuntu
PS: I want to mention the fact that this laptop has Bitlocker installed, and that all partitions have NTFS type
