I m using Acer a515-54g as a laptop which came with i5 8gen and preinstalled windows.
I already had a harddrive with ubuntu installed and was using that in some other laptop , I decided to add that to that acer laptop with windows.
the harddrive was having both ext4(for linux installation) and ntfs(my previous windows data) partitions to it , so after plugging plugging it it as a secondary drive to the acer laptop it worked but was only able to see the ntfs partitions and the linux partitions were kind of visible only in diskmanager but unexcessible.
I wanted to boot to ubuntu on that drive but i m unable.
Kindly suggest me any solution for this.
thanks
