Partition shrinking

[ssfc72]

So, on my dual boot (Win 10/Mint 18.3) 11" HP notebook, I was getting a nag that my disk space was low, when running Mint18. :-(

The notebook has a 500 MB hard drive and the Win partition had a huge amount of free space.

So, in order to not mess up the Win 10 partition, I used the Disk manager in Win 10, to shrink the Win 10 partition ( instead of using GParted).
The Shrink operation went fine and I wound up with a chunk of unallocated disk space, to the right of the now smaller, Win partition.
The Mint partition was to the right of the Unallocated disk space.

I then booted up GParted from a usb flash drive and used GParted to expand the Mint partition, to the left and into the unallocated space.
Gparted warned me that moving a Linux partition might corrupt the booting of the computer.

I had imaged for a backup, so I went ahead with the Gparted operation, fully expecting to wind up with a computer that wouldn't boot up.
To my surprise, I was able to boot into Mint and Win 10, without a problem. :-)

Now I have lots of free disk space on my Mint partition.

Thank you, GParted! :-)

This would have been a problem with the Lilo boot loader we used years ago which looked for a spot on the hard drive, an exact spot, to boot. I think Grub can search and read. Or at any rate find the right software to do a boot.

It probably just gives you that warning because moving a partition might change the boot order. Like if you moved the Linux partition to the left/before Windows 10. It likely wouldn't boot then as this change could cause a change in the drive lettering. Although I think now UUIDs are used to it probably still wouldn't be an issue and this is just an outdated warning.

Brings up my presentation about matching UUID's in grub and gparted.
