I recently had a problem
I have both Ubuntu and Windows 7 on my laptop side-by-side. When I boot up my computer I am shown a boot screen to choose between Ubuntu and Windows.
Then I formatted the partition that had Windows. But in the boot menu, Windows still appeared, but of course it's not really there, so if choose Windows, it tells me something like wrong boot record.
I have 3 partitions on my laptop:
50GB - Ubuntu 100GB ext4 80GB also ext4
Recently, I formatted the 80GB partition and changed the file system to NTFS and I installed windows there.
But now the Boot Menu is gone, although I have Ubuntu installed!
How can I get that boot screen back?
