Started boot-repair on live-usb, removed grub, and then was instructed to write in terminal sudo chroot "/mnt/boot-sav/sda5" apt-get install -y --force-yes grub-pc linux but I get:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package linux
and it says grub is still absent.
The original command should not be,
apt-get install -y --force-yes grub-pc linux
It should be,
apt-get install -y --force-yes grub-pc
If you run apt-get install -y --force-yes grub-pc linux command, apt-get tries to find and install the packages grub-pc and linux. But there is no such linux package available.
E: Unable to locate package linux
The above part from the error report is your clue.
The presence of "linux" in the install line is a bug in boot-repair, and should be reported there.
The command line reported by boot-repair is
apt-get install -y --force-yes grub-pc linux
Whether or not the word "linux" should be there is a different question.
When prompted by Boot-Repair, please type this command in the terminal:
sudo chroot "/mnt/boot-sav/sda6" apt-get install -y --force-yes grub-pc
linux command in a terminal on 1 line only. In your question it appears broken on 2 lines.
I had the same problem with Boot Repair and found that if I omit the word "linux" from the end of the command, then it installs properly. For some reason Boot Repair says you should include the word (but again, you should not).
