i have installed ubuntu 12.10 on my laptop to a folder named ubuntu in C drive. However the OS does not show up in the initial boot sequence. Do i need to change the file location/ convert it into a cd/dvd, if so How?
How exactly did you install it? Did you format a usb stick or cd? Or just copy some files somewhere?
To install Ubuntu: Download the .iso here
Download Universal Usb Installer
Use Universal Usb to properly create a usb drive to boot from, then install.
Sorry if you've done all this, but your question isn't very clear.
If I understand you correctly, you installed Ubuntu to a "folder"? This might mean one of two things:
1) You used wubi to install Ubuntu (i never tried wubi so I cant help in this) 2) you mean a partition instead of a folder? (though this is unlikely since you mentioned "in C")
If you are attempting to install Ubuntu side by side to Windows (i.e; dual boot) then you need to restart your computer & boot from the disk (or usb) & use the Ubuntu installer which guides you (note that there's a step where you need to create a partition for Ubuntu!)
Lots of resources are available online about this!
