I have a Commodore 64 and due to its age it's a rather temperamental piece of equipment, and the 1541 disk drive even more so. I'm planning to replace all of the electrolytic capacitors in it which should help a lot, but that's probably beyond the abilities of most people.

Setting up a Pi or something to boot directly to a C64 emulator would be easier and an order of magnitude less expensive for most people.
