I have fully functional Windows and Ubuntu that is broken (I accidentally broke it) and want to reinstall Ubuntu. With Live-CD, I can see:
- 3 NTFS partitions,
- one ext4 and
- one unknown.
How do I find out which partitions belong to Windows? I thought that I might delete everything that wasn't NTFS, but I was afraid. Now I am using the Install Ubuntu alongside [existing systems]... option, but I guess that this will leave my broken Ubuntu untouched. So, again, I need to know which partitions to merge (perhaps add partitions of broken Ubuntu to new Ubuntu?).
Please, how can I learn how my system is divided? Thanks a lot.
