Introduction

This wizard explains step by step how to restore Grub to your machine thanks to the graphical click-and-fix rescue suite Rescatux. You can find more information about what problems you can solve with this wizard and what you get after performing the Wizard steps at: Wizard – Restore Grub .

Wizard steps to perform

Download Rescatux

Put Rescatux into a media

Boot from media

Rescatux – Press return at boot

This wizard step will help you to identify when to press return at Rescatux boot.

Booting with CDROM or with USB built with dd

When you boot in Rescatux the Rescatux autodetect option is selected by default. Just press return. If you don’t press return it will be autoselected in 60 seconds time.

Here you are advised to use default entry: Live (amd64). If you ever get a message like:

This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropiate for your CPU.

then repeat all  the steps in order to boot into your device but in this screen select: Live (486) entry instead.

Once you have selected your entry you have finished this wizard step.

Wait for Rescapp to open

This wizard step will help you to know when to stop waiting for Rescapp to being open.

After several letters appear in the screen a graphical interface appears.

Select your Grub partition

You will be asked which is your Gnu/Linux partition. You should select your Gnu/Linux distribution partition. You should ignore loop1 partition which it is the Rescatux device most of the times.

Then press OK button.

Select your main hard disk

You will be asked which hard disk to install Grub on. Usually you should select the same disk where your Gnu/Linux partition is because usually you only have a hard disk. In some cases you need to select the first hard disk that boots when the computer boots.

Order your hard disks

Only when you have more than one hard disk you will be asked to order your hard disk in the same boot order as the BIOS boot order. That ensures that Grub knows if it’s booting from the first device to boot or from a secondary one.

Wait for Rescapp to finish

Sometimes a message is shown while Rescapp is performing the asked task. Sometimes you won’t see it because it won’t last too long. Please be patient and wait till it finishes.

Everything goes OK

Don’t be rude when asking your questions, try to be patient, that means that wait for 10 minutes for someone to reply. If no one replies understand that donations do not afford in order to pay someone 24 hours a day to answer everyone questions.

You still have the chance to ask via the forummailing list, or even trying to check in the chat if someone is finally online and available while you use another operating system or a friend’s computer.

Wizard Step – Turn off Rescatux

At the right bottom corner of your screen you will find an on/off button.

After a bunch of letters your computer will be powered off.

If you want to use your computer as everyday you are advised to remove the Rescatux media so that Rescatux does not boot instead of your regular Operating System.

  1. Thanks for this software.
    But i have a little issue. When a try booting from USB i have black screen with text:
    GNU GRUB version 2.02~beta2-9ubuntu1
    grub>_
    Without GUI.

  2. I used recatux to repair the ubuntu boot but now i am unable to boot in my windows10.
    Also after fresh install of windows the problem still persists.. Can Anyone help me out.

  3. Hello everyone, it’s been 2 days from the date of this post that I can not start my machine.
    i have a linux like system but i have a problem with my grub which ( Minimal BASH-like line editing is supported. For the first word TAB Lists possible command completions. Anywhere else TAB lists possible device or file completions).
    I try rescatux; typing some commands that I saw everywhere on blogs and others but I have not managed to solve my problem, so I ask for help in case someone has the right formula, please it is very urgent thank you .

  4. Thank you very much!!!
    Worked like a charm to restore GRUB after installing Windows 10 on a dual-booting machine.
    Just had to use these 2 options in the following order:
    1. Restore GRUB
    2. Easy GNU/Linux Boot Fix

  5. I have found both software useless!
    I am a Linux user since 98! I am using Gentoo for years! And I am an HPC admin! Rescatux couldnt boot because of amdgpu error – black screen – nothing… and the other one crushes with grub error. Don’t waste your time. .. Just fix grub manually.

    1. Yeah, that’s amdgpu s not having open sourced its code.
      Use ‘non-free’ workaround while I find a better fix (probably an additional boot option).
