My overall goal is to dual boot Linux Mint and Windows 10. The motherboard is legacy bios only.

Firstly I installed Linux Mint then Windows 10 on a secondary partition.
Because I forgot to make a separate boot partition... I moved everything 1000MB to the right, and created a ext4 boot partition at the beginning of sda.
Running boot repair on a live Ubuntu USB with the options:

  • Separate /boot partition: sda4 (the first partition on disk)
  • GRUB Legacy (figured that was for legacy bios)
  • Reinstall GRUB (default)
  • Unhide boot menu: 10s (default)

Boot Repair hangs at Purge kernels then reinstall last kernel sda1 (ins). This may require several minuets...

I have let this running overnight, the process is still running. I have done a reboot and tried again, let the process run for 3 days. Nothing different.

Boot Info Summary: http://paste.ubuntu.com/17678629/

I have had gparted open at the same time, assuming that wouldn't have an affect.

I've had exactly the same issue today. Digging through boot-repair tool logs I've found this error:

gui-actions-purge.sh: line 441: ${APTTYP[$USRPART]} ${INSTALLTYP[$USRPART]} ${YESTYP[$USRPART]} linux${$KERNELTOREINST}-generic linux-headers-generic: bad substitution

The logs are stored in the \var\log\boot-sav\log\YYYY-MM-DD__HHhMMboot-repairXX\boot-repair.log file.

The package linux${$KERNELTOREINST}-generic doesn't look like a valid package. It probably should be just linux-generic.

So I've modified \usr\share\boot-sav\gui-actions-purge.sh, replacing line 441:

local COMMAND="${APTTYP[$USRPART]} ${INSTALLTYP[$USRPART]} ${YESTYP[$USRPART]} linux${$KERNELTOREINST}-generic linux-headers-generic"


local COMMAND="${APTTYP[$USRPART]} ${INSTALLTYP[$USRPART]} ${YESTYP[$USRPART]} linux-generic linux-headers-generic"

and restarted boot-repair from taskbar menu.

It worked OK and fixed my boot issues, restoring grub on my cloned disk.

Quick how-to

  1. Boot Boot-Repair as usual, but close autostarted boot-repair tool
  2. Open terminal from taskbar menu
  3. Type sudo su - to get root shell
  4. Type leafpad &
  5. Text-editor will open. Open \usr\share\boot-sav\gui-actions-purge.sh file with it.
  6. Find

    local COMMAND="${APTTYP[$USRPART]} ${INSTALLTYP[$USRPART]} ${YESTYP[$USRPART]} linux${$KERNELTOREINST}-generic linux-headers-generic"
  7. Replace with:

    local COMMAND="${APTTYP[$USRPART]} ${INSTALLTYP[$USRPART]} ${YESTYP[$USRPART]} linux-generic linux-headers-generic"
  8. Save file, close Leafpad
  9. Leave root terminal open, you will need it later, as boot-repair will ask you to run some commands.
  10. Run boot-repair from taskbar menu and follow it's instructions.
  • Made the change and still getting the same output. Searched for other peoples experiences and found this comment stating that you cannot use a legacy bios system. And the following comment suggests that I may need the live os in legacy?

  • @Harry Well, in my case it was legacy all the way down - it worked OK. Could you post boot-repair.log? I've used TeamViewer to get it: wget https://download.teamviewer.com/download/teamviewer_i386.deb && apt-get install ./teamviewer_i386.deb && teamviewer Jun 30, 2016 at 10:13

My general approach to these quagmires is image the disks involved, then just start fresh.

Not technically helpful I know, but my advice nonetheless.
