How to install snapshot.iso to harddrive ?

Postby jenom » Tue May 24, 2016 7:42 pm

My goal is to install a Debian 8 Stretch "snapshot.iso" to another PC with empty hard drive.
Created with Unetbootin a bootable USB....booted empty PC
Grub menu had no "Install to HD" option , so continued with "live"
it worked fine, OS up & running, however do not know, how to install OS to hard drive

--can grub menu modified to add "install to HD" ?
--is there an "install" script which does do hard drive install ?

Thanks!

Have you formatted the hard drive? You can probably do so from the live iso

It's not clear to me which iso you are using. If you made your own iso with refractasnapshot, then the method of installation will depend on what installer you have in the original system. Refracta Installer must run from the live CD/USB system, so you can't run it directly from the boot menu.

If you installed refractainstaller-base, you can just run 'refractainstaller' from a root terminal. For the gui version, you need to install yad.

If you put a stock Debian iso onto a usb drive, you can run the installer without booting into a full live system, but your mileage may vary, depending on how to put the image onto the usb stick. Recommended method is to use cat or dd. Then the usb will act like a live-CD when you boot it, and all the menu items will be present.

I think I need to install this pkg:

Debian Installer desktop launcher

This is a desktop launcher for Debian Installer images. It is intended to be
used on Debian Live systems.

You probably do not want to install this package onto a non-live system,
although it will do no harm.


After all, what is the "snapshot" good for if you can not use it to restore your saved OS to HDD ?

If you want to install the exact same system with all your configurations that went into the snaphot, you should use refractainstaller, which will copy the live system to a hard drive. The debian installer will let you install debian, just like it does from an official debian install CD or DVD.

Without the ability to install, a live CD/DVD/USB is still good for a few things: some use a read-only live system for online banking, it's good for recovering a crashed system, and it's good if you want to run your own system on someone else's computer (since it's easier to carry a thumb drive than a laptop.)

if I understand correctly, in order:

1 refractasnapshot --to save current system
2 unetbootin --to burn new ISO to usb
3 usb live boot
4 refractainstaller --to re-install saved system
