Unfortunately, I installed Windows 8 (paralell to Windows 7, i. e. all files for Windows 7 were kept) but decided not to keep it. Afte having removed Windows 8 I can't start Windows 7.
I experimented with installing Linux and could start Windows 7 using Grub. Now I have also uninstalled Linux. Windows 7 can't be started.
What can I do to get Windows 7 back?

Sounds like the partitions have really gotten messed up. I suggest booting from the Win7 cd and running a repair.

If that doesn't work, I suggest bacing up your data. Your ultimate process may be a format and install, but that would be my last process unless you don't have anything important to lose.

I would start from scratch.

Fresh install of windows 7 and full format NTFS the drive.

Best way to make sure nothing is left behind from other OS

Yes, I agree, but he may other factors that stop that from happening right away. Clean install has always been my #1 choice.

Thanks for your suggestions.
 With a clean install there's a lot of job necessary to reinstall all programs, isn't there? Is there a method to reinstall (repair?) Windows 7 without the necessity to reinstall all programs?

Yes after you build a computer and are finished installing all applications
Your next strp would be to clone the hard drive.
Then all you need to do is re image your new drive and are backup and running in a short time.

Acronis is a great prodcut to use for this process check it out.

Sometimes we just have to bit the bullet and start over.

try to recover existing install as suggestions. if not success you can fresh install Windows 7, it will ask you to rename exist windows installation as WindowsOLD.it is ok, install windows 7
you are missing only boot information for existing installation. after new installation completes you can rename new installation  -  windows, program files, program data, users  folders to other name & cut paste your old installation - windows, program files, program data, users  folders folders to root of system ( C: ) drive.
then your old installation will boot without any issue.
backup your files recommended

try these two options
/ScanOs
The /ScanOs option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.
/RebuildBcd
The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD. WAZOO
