Re: re Rescue Mode (Tech Support Department)

Hi :)

Errrr is it time to think about data-recovery?  ie get a 'new' hard-drive and make that bootable and repair the 'old' hard-drive while booted into the 'new' one?

https://help.ubuntu.com/community/DataRecovery

(my variant on the advice effectively uses the 'new' partition to make the machine act as a new machine with the 'old' drive only plugged back in after you have successfully booted into the 'new' drive a couple of times.  Don't plug in nor unplug while powered up of course!).  I think in the guide they tend to prefer LiveCds but i try to go for something faster even if it takes a little while to set it up. 

Regards from
Tom :)

Hello Tom,

I fear your system partition is badly damaged, because Boot-Repair couldn't detect any GRUB executable (grub-install) in it, and worse: no apt-get executable at all.
So the problem is not GRUB.
If i were you, i would try to fix the system files this way: https://help.ubuntu.com/community/UbuntuReinstallation

Hi :)
If it's not possible to recover Grub2 is it possible to reinstall? 


Personally i still haven't got out of the old Windows-support habit of just reinstalling instead of spending time trying to analyse and fix.  Grub2 should be reasonably easy to install on almost any type of partition. 


I think i might create a special partition purely for booting from.  A boot partition.  It's a bit old-school as i haven't seen one for years but they used to be very popular.  In some situations it might be possible to copy&paste your grub config file but even if not the newer version of grub2 would probably be able to find all the OSes that are bootable on your machine. 


I don't think it finds ones inside a virtual machine that you would run from inside one of the partitions (although obviously you can install directly into a virtual machine that could then boot any bootable OSes inside that virtual machine).  I guess if you could somehow get the bios to start-up a virtual machine then it could let Grub2 boot that but i think that would be really weird and freaky and possibly even scary. 


Anyway, many apols if a reinstall has already proven impossible.  I haven't been following this thread so it might be an inherently bad suggestion but reinstalls have always worked for me! :)
