windows overwrote boot record

[tom bell]

/* previous text snipped for terse brevity */
For anyone who has lost a GRUB due to it being overwritten by Windoze,
you can search for: grub super iso
Then down it from the website and write the iso to disk.  Do NOT copy it
to disk, have ISO capable software (most can do this) make an ISO disk.
It will give you a bootable disk that you can fix GRUB boot problems. 
It won't fix a serious distro boot failure like I have suffered, but it
is good for GRUB problems.
Hope this helps someone.
