Re: Boot problem : Operating System not found.
It would've been helpful not to have snipped the "drive partition
info" section! :)
You have a gpt-labelled disk but sda1 isn't OK. As "File system", it
should have "BIOS Boot partition". "Boot sector type" and "Boot sector
info" cannot be right but I don't know what they should be.
The two "looks at sector" seem *very* wrong.
OK, hereafter I added the drive info produced by boot_info_script.sh.
I'll also try the SuperGrub2Disk ASAP.
Bye.
