Not having had enough abuse from my new HP Pavilion dm1-4310ez, I decided to swap the original disk for an SSD. Then the real fun started with EFI booting.

This HP Pavilion 15 laptop features a powerful 13th Gen Intel Core i5-1335U processor with up to 4.6 GHz turbo speed, paired with 16GB RAM and a spacious 1TB SSD for fast storage.
