I found the problem i think.
****FOR SHORT IF YOU DON'T WANT TO READ***>>>>> tried these multiple times and the culprit is the not having the "lba" flagged also, along with the "boot" flag.
@bigpup I did everything you told me too and i keep having issues then clicking stuff and trying everything i got it to work, but i was curious to why it all of sudden works and what i did that was different. So i loaded another USB the same way i was doing at first and i was getting the same problem. That eliminated downloading a bad iso and i tried all three different links from the main bookwormpup thread.
I found from comparing my setups that work and the ones that didnt work and the way i was using the installer; is that when i used gparted to format the USB for fat32 and to made sure the "boot" flag was checked in manage flags option, i was also unchecking "lba" as i thought i only want "boot" flag. So when i made another USB and left it checked and checking the "boot" flag option also together. It now boots correctly now! Everywhere. All computers. So i guess on my side the 'lba" needs to be checked in the flags. Is that a design of the USBs i got? I dont know for sure, i do have different brands.
and all that was done through bionicpup64.....i don't know why my windows computer using rufus does not work, no matter what i do.
A quick search on "lba" definition: The LBA flag indicates that a partition should be accessed using Logical Block Addressing (LBA) instead of Cylinder-Head-Sector (CHS) addressing.
Still clueless what that is, if anybody can chime in, that would be a great learning experience
Then i ran into another issue after initial setup on bookwormpup64, anywhere i clicked the desktop would switch or clear all the icons even conky and it only shows a home folder. I don't know why, but when i set up a save for my first shut down and rebooted, everything is fine now...so far.
Also got a alert/error message initially after setup i never seen: No pinboard was in use...the 'Default' pinboard has been selected. Use 'rox -p=Default' to turn it on in the future. ????
I wont ask anymore questions i have, i can get long winded or "long typed" because they don't relate to USB booting/install. Hope this helps someone going through the same thing.
