I've learned a few surprising things about Windows that I thought I'd share with the list.
Computer: Dell Inspiron 1501 with Windows Vista (on which I'm installing Buster but want to keep Windows to update my Garmin GPS once or twice a year). I was surprised to find two partitions formatted as HPFS/NTFS/exFAT (dev/sda2 and dev/sda3) (in addition to what I guess is a Dell recovery or utility partition on /dev/sda1). And then more surprised to find that, after I installed Buster and set up <darn>, that Windows was (apparently, I thought) booting from /dev/sda3. I didn't know why there were two NTFS partitions, nor why Windows booted from the 2nd one (I assumed (I know) that maybe the second NTFS partition was drive D: and set up for what I call "real user data" (things like photos, files, that the user creates or acquires). (I almost wiped out /dev/sda3 to make that into a swap partition, but fortunately dug a little deeper -- it turned out that /dev/sda2 is a Windows recovery partition, and /dev/sda3 is really the partition which boots Windows. I plan to reformat /dev/sda2 and make it into a swap partition.
