My laptop came with Windows 7 which also has extra partitions for "system recovery"(because seemingly supplying a dvd is too expensive) and a 100MB boot partition. I removed the recovery partition and now want to get rid of that small boot partition as well. I heard that it is possible to move the boot data into a folder in the main win7 partition and delete that small extra partition. How can I do it?
Was the recovery partition you deleted the 200MB Windows 7 Recovery partition, as described in:
Be very very careful not to end up with a Windows 7 installation that cannot be easily recovered in case of major system corruption.
The above article describes how to install Windows 7 and avoid this 200MB partition. The WinRE recovery environment is then stored in a folder in the root of Win7 installation drive, which is what you are probably asking for.
However, because you deleted this partition, the best thing to do now is to reinstall Windows 7. The question is whether you had the boot CD available. If you do, then you can maybe get by with only doing Repair Install to Fix Windows 7.
You can remove the partition from outside of Windows, such as a Linux LiveCD or Windows 7 installation/repair disc. You'll then need to boot up through a Windows 7 installation/repair disc and run startup repair.
You can create a system repair disc without an installation disc.
