Fix Overlapping Partitions

I (foolishly) tried to shrink the boot partition on the active OS (i know, i know).
Used gnome disks, which hung during the attempt.

Strange thing is, the computer still boots, and everything works.
But i assume i must first fix this error, before shrinking the book partition (the right way).

Trying to follow these steps,

Just wanted to get some confirmation before i proceed.

The boot partition doesn't seem to overlap anything.

# fdisk -l /dev/sda

If you read the partition in order of start, then it looks like sda9 is the too-big partition. It overlaps the beginning of sda8.

Device     Boot     Start       End   Sectors  Size Id Type
/dev/sda1  *         2048  69398726  69396679 33.1G  7 HPFS/NTFS/exFAT
/dev/sda2        69400576  80957439  11556864  5.5G  6 FAT16
/dev/sda3        80959488  81922047    962560  470M 27 Hidden NTFS WinRE
/dev/sda4        81922110 312580160 230658051  110G  f W95 Ext'd (LBA)
/dev/sda5        81922112 250687487 168765376 80.5G  7 HPFS/NTFS/exFAT
/dev/sda6       250689536 266416127  15726592  7.5G 83 Linux
/dev/sda9       266418176 312580160  46161985   22G 83 Linux
/dev/sda8       272730112 274790399   2060288 1006M 82 Linux swap / Solaris
/dev/sda7       274792448 293687295  18894848    9G 83 Linux

So sda9 the one who's end-sector i should edit, correct?

(I noticed sda9 end is the same as sda4 end. sda4 is the extended partition, so i don't need to worry about it, right?)

Just an observation: 7 and 8 lie wholly within 9.
