  3. Jaime

    I have Linux Mint 20 latest updates as of 9/22/2020 and it worked
    update-initramfs: Generating /boot/initrd.img-5.4.0-48-generic
    I: The initramfs will attempt to resume from /dev/sdb3
    I: (UUID=06628ac9-c7ef-4c63-8c5e-f2a94dcf777b)
    I: Set the RESUME variable to override this.

    How open a terminal ??
    My pc turns down soon after this.

      That is not the problem I am addressing. You should reinstall the OS.

    It is the same problem. Boot fails on initramfs. Cannot continue, so cannot fix it. Reinstall does not help.

    Worked like a champ, though I went with “sudo nano…” to edit the initramfs.conf file because that’s more familiar to me, I’ve never seen the admin:/// path before.

    Worked… Linux Mint 20 Cinnamon

    My computer replied, “xed not found”
    I see in a comment that someone used sudo nano.
    I’ll try that next.
