Remove windows 7 entry from grub
I recently installed ubuntu 10.04 LTS and formatted my windows 7 hdd, but the windows 7 entry is still showing in grub. How can I remove the entry from grub?

You should edit the /etc/default/grub and add the following line:
GRUB_DISABLE_OS_PROBER=true
save it and perform
sudo update-grub .
It will remove Windows from your GRUB menu list.
Hide/remove Windows entry from Grub menu list
The problem with these answers is that they do not address the underlying problem - when Windows is installed, it scans all drives on the system and 'litters' qualifying drives with 'Recycle' folders and other Microsoft OS what-nots, that Grub then takes to be an existing M$ OS.
Including the "GRUB_DISABLE_OS_PROBER=true" line will prevent ALL other operating systems from being detected, including other Linux OS's.
So the best fix is simply to delete these additional files/folders that Windows has created prior to running "update-grub". Window's menu-items will no longer be present in the Grub menu.
Ubuntu 10.04 LTS uses Grub2, which no longer uses the /boot/grub/menulist.lst file for configuration.
Instead, you should edit the file /etc/default/grub.
If your hard disk still contains a Windows partition, add the line:
GRUB_DISABLE_OS_PROBER=true
to prevent Windows being added to your grub menu.
To write the change, run
sudo update-grub
which will write a new /boot/grub/grub.cfg file.
You can then run
cat /boot/grub/grub.cfg
to check that your Windows entry has disappeared.

If the entry was manually created, all you need to do is remove the corresponding file in /etc/grub.d/ using the command:
sudo rm /etc/grub.d/<filename>
Make sure you know what you're doing, you don't want to delete the wrong file as it will cause boot problems.
Also, you might not want to disable os-prober if you have a dual- or multi-boot system.
Disabling os-prober wasn't correct solution in my case - I had 2 Windows entries and just wanted to remove one incorrect. I was able to achieve desired effect using following Grub configuration:
1.Check UUIDs for the disks using the command:
sudo blkid
2.Update /etc/default/grub file by adding the line:
GRUB_OS_PROBER_SKIP_LIST="UUID_OF_DISK_YOU_DONT_WANT_SCAN1 UUID_OF_DISK_YOU_DONT_WANT_SCAN2"
3.Regenerate Grub configuration:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
NOTE: grub2-mkconfig due to some reasons still displays information about the ignored disk, but it wasn't generated to final /boot/grub2/grub.cfg file.
