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.

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.

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.
