The situation is this, on my laptop the hard disk partitions are:
— Windows OS (1)
— Linux (2)
— Ubuntu OS (4)
— — swap (5)
— — Ubuntu Data (6)
— Windows Data (3)
I had to reinstall Ubuntu on the partition "4". After formatting partition "4" noticed that the section "3" has disappeared. Went into Windows and ohrenel! Section "3" has not been opened, have shown that it is occupied 0 bytes, free 0 bytes. File system became RAW. When you try to open offers to format it. The drive is visible in Windows. Disk important information!
How can I restore the partition?
Know how to format, install system too. What happened this time a mystery.
All Windows partitions in NTFS, Ubuntu is ext4.
