The journey continues with the house network Thinkpad T580. Slackware 15.0 has been used without commotion for several weeks.
On the agenda was wiping Windows and changing the partition scheme. The system came with Windows 10 pre-installed using an EFI partition on an NVMe SSD. Windows is not much needed here. Some people might pontificate about the alleged benefits of EFI, but EFI is overkill on a computer using only one operating system.
The T580 BIOS supports “legacy” BIOS. Except that an EFI partition seems to be required to boot from NVMe SSDs.
Then a new USB storage device was purchased. An NTFS partition was desired to play sneaker net with a distant family member. An NTFS partition can be created and formatted in Linux, but past experience is using Windows for that task is more reliable.
For now EFI remains in place as does Windows 10. Thus far Windows has not been allowed to connect to any network interface. Is Windows designed to have a temper tantrum after several months without connecting? Time will tell.
Windows is not part of the GRUB boot loader. The only way to boot Windows is with the laptop hidden boot menu invoked with the
F12 function key.
