ONE:

Most existing Windows EFI partitions are about 100MB in size.

When migrating from Windows 10 (or W11 etc) to Linux Mint, it is important to note that Calamares, the Linux Mint installer, requires a minimum of 300MB for the EFI system partition.

For dual or multiple booting it is advisable to make the EFI partition at least 500MB.

Prior to using the Linux Mint installer, I advise using GParted to create a 500MB EFI system partition...

HP 455 G9 with no wifi - solved using backports

Posted 09-23-2024 at 04:22 AM by beachboy2

While installing Peppermint OS on an HP 455 G9 ProBook, I discovered that no wifi was available.
