Hey there, so recently i have been to Ubuntu and install it in my PC but unfornuately it shows two OS that is Wind 7 and Ubuntu and which is makes the perfomance of PC bit slow so i request you guys to please help me in deleting one of the OS from my PC so that my PC works in a normal way and deleting the WIN 7 would be my choice !
Hope i will get replies soon as i got a project next week which i need to work on my PC !
1.) Having two operating systems in dual boot has no effect on pc performanc (only if you would run virtual machine over other OS)
2.) You can easily remove Windows partition with help of utils, start reading this https://help.ubuntu.com/10.04/hardware/C/disks.html
