### Total disk wipe
_This is an excerpt from a comment I made on the original [thread](https://www.reddit.com/r/linuxquestions/comments/g88hhs/need_help_installing_ubuntu/)._
1. Launch a live usb
2. Launch a terminal and run “sudo gdisk -l” and find and note down the name of your main disk, use this in step 2
3. On the assumption your disk is “/dev/nvme0n1” (your screenshots suggest this is the device name) run “sudo gdisk /dev/nvme0n1”
4. In gdisk, press “x” (expert mode)
5. In gdisk, press “z” (zap) and respond yes to all questions- this will remove both gpt and mbr partition tables
6. Quit gdisk
7. Reboot
Your disk should now be as blank as is possible without writing zeroes across the whole disk.

The L490 does not have a CD drive, and yet the only way Lenovo provide to update firmware outside of Windows is a non-USB iso file available (available at time of writing [here](https://download.lenovo.com/pccbbs/mobiles/r0zuj12wd.iso)). Thanks Lenovo.
