How to "unclamp" a volume?

Question

linux

Hi guys. There was a need to put debian. Classmates immediately compressed part of the volume, allocated memory, but did not create the volume.
I made an installation flash drive, changed the priorities in the BIOS, the installation began. At the stage of distribution, the memory on the disk came to a standstill, because there is no volume. :(
I went into disk management again in Windows, decided to create a volume. An error occurred after futile attempts

. What should I do? :)

Answer 1

Offtopic - well, classmates mean they messed up, and we are here to rake.
Look at your reduced disk in the context menu. There should be an item about resizing.
And put Debian in a virtual machine - VirtualBox is called.

Answer 2

If you boot from a livecd or flash drive, install gparted and move the partitions however you like.
Windows may break. In order not to break, you can reduce the size of its partition from under Windows so that there is free space, and then resize the ext4 partition with livecd.
In general, these experiments are insidious. And they take a lot of time. They say LVM helps.
