Thanks Paul for reporting this bug.
The problem is that there are errors when reinstalling the GRUB of your Ubuntu
12.04 in the MBR of sda:
1) update-grub returns the following error:
/usr/sbin/grub-mkconfig: 1: /usr/sbin/grub-mkconfig: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
2) grub-setup /dev/sda returns the following error:
error: cannot stat /boot/grub/boot.img.
3) grub-install --recheck /dev/sda returns the following error:
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/grub-install: 1: /usr/sbin/grub-install: sed: not found
/usr/sbin/: Not found.
I hope a GRUB expert can interpret those errors. (FYI Boot-Repair uses
the above commands via a chroot in the 12.04)
** Summary changed:
- No Ubuntu or Windows boot after failed boot-repair
+ grub-install returns "1: /usr/sbin/grub-install: sed: not found" error
** Changed in: boot-repair
Status: New => Triaged
