The problem with bootloaders is they really can’t spare a lot of storage. Storing different QR codes for all the common errors might be asking too much.

- antonkochubey 2y agoCurrently EFI partitions are on the order of 300-500 MB for common installs, that'd allow you to store millions of PNG-compressed QR codes. Or even better, a small library which'd allow bootloader to generate it on the fly.

- Cthulhu_ 2y agoYou don't need to store the whole QR code, just code to convert an URL into a QR code. Or a good, short URL that can easily be typed, e.g. "microsoft.com/errors/1234"
