Puppy's my main everyday OS, but I have several other partitions with other Linux distros plus the original Windows 10. When trying to upgrade MX Linux from 19 to 21, I remembered that it would't boot from Puppy's Grub4Dos (64 bit vs 32 bit?), so I went to Puppy Package Manager and found Grub2 and installed and ran it. Maybe I'm getting senile.
Now it created an "sda" icon (a folder with a gear on top of it) at the bottom along with the usual "sda1," "sda2," etc. Computer still booted into the Grub4Dos menu, so I ran the "Grub4Dos bootloader config" again (from the frugal installed Puppy on the hard drive and again from a USB flash drive) and it gives me the following error in the grub4dosconfig.log file:
/usr/sbin/grub4dosconfig

/dev/sda Bootalbe: yes,
Gparted only lists "sda" and gives this warning:
"Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sda is missing"
What can I do to get back to normal? How to get rid of the superfluous "sda"? The more I learn, the less I know...
Thanks for any advice.
