My computer recently started giving me an error right after I installed gnome. It said:
WARNING: failed to connect to lvmetad. Falling back to internal scanning
I need help to fix the error.

Download Ubuntu from here. If your computer was made in the past 8 years then you probably want the 64 bit version. If not then use the 32 bit version.
If you do not know how to make a bootable disk then click here. I prefer to use
unetbootin with USB which can be downloaded from here. If you use the USB method then make sure to use a partition on the drive that is smaller than 4 GB and is FAT32.
Insert the disk into the tray or the USB drive into the port. Reboot and select to boot to that device. Go ahead and let it boot to the normal live session. Click on the desktop icon to install Ubuntu.
Somewhere, around the 7th step as I recall, you're given an option. The option reads "Erase disk and install Ubuntu." Select that, instead of selecting "something else." This will completely wipe the entire system and give you a brand new starting point per your request.
