LLOS 6.4 install on USB will not boot.

[LarryB1607]

Extracted iso to a freshly formatted USB drive.  All operations were successful.  I can see all items in the drive in both Windows and LLOS 5.8.  Macrium Reflect does not see the drive and Gparted sees the drive as unallocated.  The drive was formatted in both NTFS and fat 32 with the same non bootable results.  I have never had this issue before and boot LLOS 5.8 from a USB external HDD.  This same USB drive had Ubuntu Cinnamon installed on it last month and it booted fine.

What is the purpose of "Macrium Reflect"? Are the Linux Apps ended?
I use CloneZilla Live (Low level backups) and LuckyBackup (1:1 backups). LuckyBackup is a GUI for rsync, a Command line tool.
So, am I missing something?
As for the invisibility, if you use more windows tools than Linux tools, this is where you get.
In 12 years of daily use of Linux, I never had issues related to drive (any storage media) visibility, be it MS formatted or Linux formatted.
Further more, I used various tools for writing the ISO and all went well.
However, I never mix tools from MS world with Linux Tools.
Maybe you used a MS tool or an old distro for formatting and the support for file formats being old, might lead to such a result.
Have you considered using Linux Lite 7.0?
I installed it on a Sony VAIO 2011 machine (2 core, 2 thread, 4 GB RAM) one month ago and works fine.
The only similar behavior has the Ventoy drive, and this is because it has multiple file format sections, in order to be usable (theoretically...) on any machine with any OS.
I suggest you re-write the boot media, by-the-book. What you mean by "I extracted"?
No image writer extracts the files. It writes the image and this is a low-level operation, meaning copying bit-by-bit all the data. This has nothing to do with extracting files, like in un-archiving them with compression tools.
