Progress report:
It only got worse. The boot-repair utilities retrieved from ubuntu didn't fix
anything:
>> sudo add-apt-repository ppa:yannubuntu/boot-repair [Enter]
>> sudo apt-get update [Enter]
>> sudo apt-get install -y boot-repair && boot-repair [Enter]
[Running these steps on sdb, the USB-connected 500GB hard drive, produced an
output file sent to http://paste2.org/[........] but that link was dead.]
Then I tried downloading Boot-Repair-Disk-64bit from
http://www.sourceforge.net/p/boot-repair-cd and that produced a long text
file that I saved, and it suggested the following suggested repair:
>> The default repair of the Boot-Repair utility would reinstall the grub2 of
sda5 into the MBR of sda.
>> Additional repair would be performed: unhide-bootmenu-10s
fix-windows-boot
After several tries with these two boot-repair facilities, the Trisquel 7
OS's on my various USB-connected hard drives will start OK from the grub menu
with grub P/W's (not yet unified) but the Windows 7 partition's boot manager
has been made useless/damaged.
As I have tried "the default repair" several times, choosing the "usual
repair method," that hasn't fixed the Windows bootup routine. Is there
another way to obtain "reinstall the grub2 of sda5 into the MBR of sda" ?
The commands, "unhide-bootmenu-10s" and "fix-windows-boot" are not recognized
by the console, even with sudo prepended to them. Maybe they're to be run
from SourceForge's boot-repair-cd ?
