How to uninstall Ubuntu without losing win7?

Question

linux

I have windows 7, I installed via ubuntu flash drive. I created a separate partition for it, allocated 20 gigabytes to it, somehow after installation I lost the partition for ubuntu and 20 gigabytes of space is free, you can distribute them to any partition, but that's not the point. The bottom line is that ubuntu was installed on the C drive. Now I need to uninstall Ubuntu without losing windows 7, is it possible to do this?

Answer 1

1. Boot from liveseed of the same ubuntu.
2. Run Gparted and delete the Linux partition.
3. Boot from the Windows installation disk and "Restore" it, in fact, simply returning its native bootloader instead of the hornbeam installed by Ubuntu.
4. PROFIT.

Answer 2

You most likely installed Ubuntu on the Windows partition using Wubi (well, or whatever it's called, you could have already renamed it) This
is how it's done https://help.ubuntu.com/community/Wubi#Uninstall_f...
There is also an article about removing such an installation.
If I'm right, then you have 20 GB left unused and you can return them right now, without uninstalling Ubuntu.
