I have two OSes, Kali and Ubuntu. But I would like to delete Kali and allocate all the disk space to Ubuntu. When I boot, I get the Kali menu. How can I do this, if I do not have access to Ubuntu?
Also, will the data in Ubuntu be lost?
If you are not seeing Ubuntu as an option on boot (even when launching the computer boot menu) you may want to boot with a live linux distribution from an usb drive and then repartition your hard drive with gparted as recommended by JerareYoshi.
The steps would be:
BACK UP ANYTHING YOU DEEM IMPORTANT before doing anything with your partitions.
Boot from an USB live distribution. Here is a tutorial to do so if you don't find one.
From the live distribution, open gparted and follow the instructions on this thread to merge back one partition to the other.
Reinstall GRUB or GRUB2 or the boot loader of your preference. Boot-Repair is yet another tool that repairs your boot sequence. This will allow you to boot your computer into the Ubuntu distribution of now merged hard drive.
