I've been playing around with ubuntu a lot lately, and I want to use it as my primary OS. When I first downloaded it, I think that grub2 became the boot master instead of the windows 7 bootloader. Every time I tried to boot windows 7, it would fail. The windows 7 disk didn't come with my desktop, so I couldn't find a way to fix it. I like ubuntu more though so I'm ok with that. I downloaded GParted to delete the windows partition and make ubuntu the primary partition, and this is where I'm stuck.
This is what is showing up on GParted:
/dev/sda1
- FILE SYSTEM: fat32
- MOUNT POINT: /boot/efi
- LABEL: SYSTEM
- SIZE: 100 MB
- USED: 21.89 MB
- UNUSED: 78.11 MB
- FLAGS: boot
unallocated
- FILE SYSTEM: unallocated
- SIZE: 263.28 GB
/dev/sda5
- FILE SYSTEM: ext4
- MOUNT POINT: /
- SIZE: 182.03 GB
- USED: 16.21 GB
- UNUSED: 165.82 GB
/dev/sda6
- FILE SYSTEM: linux-swap
- SIZE: 3.58 GB
unallocated
- FILESYSTEM: unallocated
- SIZE: 16.78 GB
I don't know what to do next. I unmounted sda1 and sda6, but can't unmount sda5, which is the partition for ubuntu that I'm using right now. When I try to unmount it, it says:
Could not unmount /dev/sda5
The partition could not be unmounted from the following mount points:
/
Most likely other partitions are also mounted on these mount points. You are advised to unmount them manually.
I've unmounted everything else though I think. I can't create a partition table because of that either. I would try more things but I don't know what to do. I don't want to mess up anything either. Any Ideas?
