Grub is not Detecting my windows OS

[vamshikrishnavk]

I have recently installed "DEBIAN 9" alongside with the windows.First the grub detected my windows 8.1 OS and then when i logged into the debain there was a software update to install then i installed the update and after Re-starting the Laptop i dint find the windows OS in the list. I've tried many ways from searching google but it din't seem to work.It only shows

1-- *proxmox Virtual environment GNU/Linux and
2-- Advanced options for Proxmox Virtual environment GNU/Linux


I have added these sources to the source list


{Attention!
Before you start install these packages first:

apt install curl wget apt-transport-https dirmngr

Hi there
Run:

Code: Select all

os-prober && grub-update

[kedaha]

Sorry, I mean update-grub

[vamshikrishnavk]

I've tried that but that isn't working...

[kedaha]

I'm not familiar with most of the sources you have posted or the effects their inclusion might have on Debian so I cannot say for certain but it looks as though the Proxmox, which is a server virtualisation environment has taken over the grub menu. I see you have also included webmin, which is a web-based interface for system administration. You surely don't intend to use your laptop as both a desktop and a server?

I advise against the inclusion of the unofficial Debian Multimedia repository because it can break Debian if it hasn't done so already.
Really, you should edit your sources list to only include what you need by putting a # in front of any unnecessary entries and try to uninstall any superfluous third-party packages from the system and then run the previous commands again.

It's NOT a good idea to select everything at debgen.simplylinux.ch and put the resulting list in the /etc/apt/sources.list

Finally, please read Don't break Debian.

Ok,that helped me thanks .....for that
