Hello, I'm a total beginner in linux I have just installed ubuntu alongside windows 7 and it doesn't show any option to boot ubuntu It just only boot windows 7

You should be a bit more detailed in the steps you've taken to get to this point. It depends on the order you installed them and the configuration of your system...
Answer a few questions to help us help you:

1. Did you install Windows first?
2. Are both OS sharing the same drive?
3. If No to both of those questions: Did you set the drive with Ubuntu installed as the first boot option in your BIOS?

I have installed first windows and then ubuntu I selected the option to install ubuntu alongside windows and I set both OS in the same hard drive

Do you know if the BIOS in your PC is set to EFI/UEFI and possible secure boot?

Thanks OldFred - all the things you've posted on this is what made me think that something else, perhaps efi, was going on, but I'm way over my head trying to figure any of it out.

You might have more luck here and as you've stated you're a total beginner with Ubuntu, helpers will be gentle.
