Hello! This is my first post to this forum although I've been reading it for a few months now. Please be gentle .
I have been trying to get Puppy Linux to boot from a USB flash drive (thumb drive). I'm able to get it to boot the first time. However, after I go through the process of saving my session and shutting down the computer, the computer will no longer boot from the thumb drive. I've tried a few different ISOs, including fossapup64-9.5.iso and friendly-fossa64-v1.0.iso. I've used rufus version 3.17p to create the bootable USB drive. I've tried creating a persistent partition and saving my session to that partition (puppy save folder). I've tried using a single partition formatted as FAT32 and saving my session to a puppy save file. In all cases, I can boot into Puppy Linux for the first time off the thumb drive, make any edits and personalizations I'd like, and use the OS as normal. However, after I shut down and go through the save steps, the computer will no longer boot off the thumb drive. The next time I try to boot off the thumb drive, the LED on the thumb drive blinks a few time and then nothing else happens. If I do nothing, eventually the computer just boots into Microsoft Windows instead (I presume there is a timeout in the bios[?].)
On my most recent attempt, I was using a single partition and a puppy save file, saving that puppy save directly to the thumb drive. I subsequently booted into Windows and tried copying the puppy save file out of the thumb drive, and then tested booting from the thumb drive again. With the puppy save file missing, this time Puppy Linux did try to boot, but then (obviously) threw errors and would did not complete the boot up because it could not find the puppy save file. I booted back into Windows and copied my puppy save file back onto the thumb drive, then tried to boot it again. This time, Puppy Linux loaded all the way to the desktop and all my settings from that first session were there. Confused, I made minimal changes, then shut down the system. I powered the system up one more time and, once more, the computer failed to boot off the USB and eventually booted into Windows instead. I'm at a loss at this point and would welcome any suggestions on the best way to proceed.
The computer I'm using is a Toshiba Satellite L755 originally running Windows 7 Home Premium. It has a 2.20 GHz Intel i3 processor and 6GB of RAM. The system is a 64-bit OS.
