I deleted windows from dual-boot system and now I have problems

[hashcode]

Hi, I had Ubuntu/Windows 7 dual boot. I decided not to use Windows anymore, so I deleted it's partition (using Gparted) and formatted it to ext4. Then I did update of grub.

Here are few issues I am having now:

1. The new partition won't automount
2. I can not use new partition. It has only one directory - lost and found. I can't copy data there.
3. Grub still has Windows 7 option (it doesn't work of course)
4. Grub fails to boot (it says it didn't find /windows partition), so I have to always skip that manually

Thanx for help!

Here is a link that has a section on repairing grub. If this was a Wubi installation this will not apply because Wubi installs Ubuntu inside Windows .If Windows has been removed so has Ubuntu.

if windows is truly gone this will update the menu.

sudo update-grub

With ext4 partition you have to set ownership & permissions. Best to permanently mount with fstab.

sudo mkdir /data
sudo mount /dev/sda5 /data
#where sda5 needs to be your drive, partition
#if not known to list partitions
sudo fdisk -l

#If you cannot read and write then change the permissions. Not for NTFS
# Note that the -R is recursion and everything below is changed, do NOT run on system partitions & be sure of mount point.
sudo chmod -R 777 /data
sudo chown -R $USER:$USER /data
#where $USER should be your login name
#or to see user
echo $USER
