[Solved] How do I install os-prober and fix dual boot issues?

I have installed Bunsenlabs after installing Win 7, however I do not see Win 7 in the grub.

Note: All commands are run as root.

update-grub

results in the following,

Generating grub configuration file ...
Found background image: /usr/share/images/desktop-base/desktop-grub.png
Found linux image: /boot/vmlinuz-3.16.0-4-amd64
Found initrd image: /boot/initrd.img-3.16.0-4-amd64
done

I tried using

os-prober

to find Windows, however it doesn't seem to be installed.

-bash: os-prober: command not found

So I tried installing it,

aptitude install os-prober

but it results in the following,

No candidate version found for os-prober 
No candidate version found for os-prober
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 16 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

Any help is appreciated.

SOLUTION==============================
Make sure that the repository lists are correct with main, contrib and non-free components., if not edit it. Then use the following commands.

apt update
aptitude install os-prober

Re: [Solved] How do I install os-prober and fix dual boot issues?

Looks like you are missing the main jessie repositories.

What is the output of:

apt-cache policy

Also, is Windows installed in UEFI mode?

If you don't know then please post the output of:

sudo parted -l

I reckon that Windows in installed in BIOS mode, but how do you find it out from the above output?

Follow up on my original question:
I installed os-prober by including its repositories in the sourced.list file and then,

apt update
aptitude install os-prober

I then, probed other OSes, updated my grub and now I am able to boot to Windows. However any light on the above outputs will be appreciated.

Re: [Solved] How do I install os-prober and fix dual boot issues?

Here's the output for apt-cache policy

That is not the full output, please don't crop stuff like that.

It seems to show the jessie repositories -- the main component at least, I presume that contrib & non-free were in the section you cropped out?

At any rate, os-prober is in main and so should have been installable...

I installed os-prober by including its repositories in the sourced.list file

Can you please elaborate on this?

What is the full output of `apt-cache policy` now?

If there is an EFI system partition present on the drive then Windows will be installed in UEFI mode.

Your drive does not have such a partition and so Windows must be installed in non-UEFI mode.

Sorry about the crop, that was unintentional, probably a mistake while copying..

Here's the output, This is the output after I installed os-prober and fixed grub. Sorry, I did that before you had replied to my post, hence.

I went to official os-prober download page and as described there, added the line

deb http://ftp.cn.debian.org/debian jessie main

to the sources.list file (sorry typo earlier). Then,

apt update
aptitude install os-prober

Re: [Solved] How do I install os-prober and fix dual boot issues?

Sorry, I did that before you had replied to my post, hence.

Ah, I see, thanks for the explanation.

So it seems that you did not have the main Debian jessie repositories -- did you select a mirror during the installation process?

You may also wish to add the contrib & non-free components to the added Debian jessie source line, as per https://wiki.debian.org/SourcesList#Exa … urces.list

More critically, you seem to be missing the Debian Security repositories -- these should be added ASAP.

Use this command to edit your sources:

sudo apt edit-sources

Be sure to update the package database afterwards:

sudo apt update

Re: [Solved] How do I install os-prober and fix dual boot issues?

No, I didn't select any mirror during the installation. I couldn't connect to the internet at that point. That explains why the main repositories weren't installed.

You may also wish to add the contrib & non-free components to the added Debian jessie source line, as per https://wiki.debian.org/SourcesList#Exa … urces.list

After the installation I ran bl-welcome to update all these, however I faced some error while adding contrib and non-free components. Therefore I continued typing n at the prompt.

More critically, you seem to be missing the Debian Security repositories -- these should be added ASAP.

Use this command to edit your sources:

sudo apt edit-sources

Be sure to update the package database afterwards:

sudo apt update

This is how my current sources.list look when I edit it using nano,

# 

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Bin$

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Bin$

# Line commented out by installer because it failed to verify:
#deb http://security.debian.org/ jessie/updates main contrib non-free
# Line commented out by installer because it failed to verify:
deb-src http://security.debian.org/ jessie/updates main contrib non-free
deb http://ftp.cn.debian.org/debian jessie main 

Will uncommenting some lines as the following do?

# 

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Bin$

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Bin$

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free
deb http://ftp.cn.debian.org/debian jessie main

Yes but you don't need the "deb-src" line unless you want to patch the Security fixes (unlikely).

As I mentioned (and perhaps this may be relevant to your other thread), contrib & non-free may also be needed for a fully functioning desktop.

You also seem to need "jessie-updates", please refer to the example sources.list to which I linked in my earlier post.

Re: [Solved] How do I install os-prober and fix dual boot issues?

As far as I understand, jessie main, jessie-updates and jessie/updates are three different repositories.

This is how my sources.list look now.

deb http://httpredir.debian.org/debian jessie main contrib non-free
deb-src http://httpredir.debian.org/debian jessie main contrib non-free

deb http://httpredir.debian.org/debian jessie-updates main contrib non-free
deb-src http://httpredir.debian.org/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

Am I missing any other security repositories?

Re: [Solved] How do I install os-prober and fix dual boot issues?

No, that all looks fine now

Remember to upgrade your system:

sudo apt update && sudo apt upgrade

Check the final output for any "Packages left unupgraded" (or so) and use `sudo apt-get dist-upgrade` if there are any, firefox-esr needs this special treatment (and maybe some other packages as well).

Re: [Solved] How do I install os-prober and fix dual boot issues?

Yes, I just finished updating. dpkg was interrupted. It asked me to correct the problem manually.

dpkg --configure -a

Will be upgrading as soon as it finishes.

I will check for packages left unupgraded, but what does dist-upgrade do? Alright.. found it here....http://askubuntu.com/questions/81585/what-is-dist-upgrade-and-why-does-it-upgrade-more-than-upgrade

Thanks a lot for you help... You have been really really helpfull.. Getting deeper into linux... hence so many question!
