In another thread I was upgrading a Trisquel_7 installation to Trisquel_8
when the
computer froze ... and I could only force a stop with the power button. After
that
it would not boot and now displays a kernel panic whatever legacy O/S is
chosen in
grub's boot menu.
Now I am using a functional live Trisquel_8 thumbdrive that worked OK with my
Lenovo T420 laptop when I last tried it.
The M/B's BIOS recognizes the thumbdrive as a Verbatim STORE, and I managed
to
force the selection of that USB thumb drive as the 1st boot device, but when
I
reboot, the message "isolinux.bin missing or corrupt" appears, followed by
"Insert
boot media in selected boot drive" but nothing happens, regardless of which
USB
port into which the thumb drive is placed. Pressing also had no effect.
Along the way, I was confronted with the message,"Enter CURRENT password"
when I
attempted to enter Setup ... but after guessing that entering nothing at all
might get me somewhere (it did) I changed that nonexistent password to the
same
grub password that I had entered into the grub files of the other 'puters
that
I am maintaining.
I tried the US thumb drive in another Desktop PC that has an identical Intel
D86GLC motherboard, and that board also responds with "Insert boot media into
selected boot device" after I force the USB Verbatim STORE drive's
recognition,
this time without the "isolunux.bin missing or corrupt" message beforehand.
On a third desktop, this one bought with Ubuntu installed in it by Micro
Center,
the USB thumbdrive boots into Live trisquel_8 without any further adjustments
to the BIOS, probably because that's what I used a couple of months ago to
upgrade
its Trisquel_7 secondary O/S to trisquel_8. That means the thumb drive is OK.
What's the magic handshake that the Intel D865GLC motherboard's BIOS wants,
or
is there a need to upgrade that BIOS ?
