UEFI boot is amazing, and I just love getting to a desktop in under 10 seconds.

However, this makes the installation of Ubuntu fraught with peril.

Is there a way to image the whole drive in case the installation of Ubuntu screws things up?

Also, should I just install another HDD?

I have sought this forum out, and made the two usernames necessary for it, to ask how I might go about installing a second HDD or SSD on my L521x Dell XPS 15 laptop.

I think I just need to buy a SATA caddy for a 2.5" drive designed to replace a disc drive, and either a 2.5" SATA drive or a 1.8" SATA drive, right?

Could I buy a 1.8" SATA SSD to fit in this, as well?

Is there anything else I need to do other than buy a caddy, an SSD, and a Torx #5 tool?
