Hi y'all, I'm back, but still with no joy. Here's what I've done so far today...
I changed my BIOS boot sequence back to (1) USBstick, (2) CD/DVD, (3) sdb-Ubuntu, (4) sda C:Windows
I tried to burn the boot-repair-disk-64bit.ISO to DVD:
I put a new DVD into reader...
Right-clicked .ISO file & chose the wrong item ( (these are not exact quotes, just what I remember)
Right-clicked .ISO file again & chose to OPEN WITH OTHER APP, and then from the resulting window, chose "DISK IMAGE WRITER" (A window opened Titled: "RESTORE DISK IMAGE, showing <disk boot-repair-disk-64bit.ISO> as source and asked me for destination, however CD/DVD was greyed out and not selectable.)
I have tried this with the ISO both mounted and unmounted.
I couldn't find any choice that offered Create or Burn Disk Image.
I tried again with an empty USB-stick inserted, but USB wasn't offered as a destination at all.
(I know the USB-stick has a Linux-readable file system because Linux shows it with the proper name in the left panel and I've written to it from Linux before.)
I'm assuming the new CD/DVD has FAT32 file system (Ubuntu shows it in left panel as "blank" CD/DVD), but I don't know how to tell if this is true, or not.
================================================================================================
TERMINAL:
I pasted my first try of doing this in the
4th post box from the top. This is my second try. If I made a syntax error, I can't see it.
...............WITH THIS TRY, i HAD A BLANK CD/ROM IN THE READER AND AN EMPTY USB-STICK IN A SLOT
