I was struggling to get an OS installed on my cousin's dell at one point. This machine came with that Intel Optane...shit with a spinning rust hard drive, I was replacing it with a straight-up NVMe SSD. Windows would get well into the install process, and then bomb out with an error that was something like 0x123a039f34798cd76eb1 UNDEFINED ERROR. This of course was in the Windows installer, which isn't a functioning desktop environment, so I had to type that manually into my laptop to google it, and got very few results.

I tried Linux Mint, and it apparently had the same problem. It said something like "BIOS Storage config error. Unable to mount file system. It may be that such and such setting is incorrect in the BIOS. See this page for further details." The last sentence was a hyperlink to a wiki that discussed the problem, which opened in Firefox because this installer runs in a live environment, AND IT HAD A QR CODE LINK IN THE ERROR MESSAGE to the same page so you could easily copy the link to an external device. Y'all that was a white glove concierge deep tissue massage of an error message.
