I have found this problem in my days of searching, but none of the solutions I have found made any difference.
I have been running kodibuntu for years.
Prior to that, XBMCbuntu, all the way back to XBMC on an actual Xbox.
(So I have been around the block a little)
Kodibuntu is dead, so I have been trying to replace it with LibreElec, and no dice.
The machine I am working on is an old Core2Duo HP desktop.
I have never had any problems installing the 30+ linux based distro's on it in the past via USB installer drive.
But now, here I am.
No matter what method I use to create a libreElec USB installer, it will not boot.
"Non-System Disk or Disk Error"
I'm pretty sure the last time I have been frustrated by this screen, was 1993, trying to get Windows 3.1 to install off a floppy drive.
(a REAL floppy drive. Not that rigid 3.5" crap people call "Floppy" for some reason)
This machine does not use UEFI.
Is that the problem?
Every forum thread I have found with similar issues has resulted in comments like, the bios settings must be wrong, the usb drive is probably broken, or the usb drive wasn't created properly.
My problem is definitely none of those things.
As far as I can tell, the usb installer is supposed to boot on either BIOS or UEFI platforms, but maybe there's some sort of bug regarding the backwards compatibility on some BIOS machines?
For now, I guess I'll just need to go back to super old kodibuntu, but I would really like to figure this out before I throw a perfectly good machine through a perfectly good window.
Thanks
