Linux nerds asked: partitioning the OS afterwards?

I installed Linux Mint on my laptop. At that time simply partitioned the entire hard disk (1TB)
Now I want to have Windows 10 as an additional OS aufm laptop. Stupidly, of course, the hard drive can't repartition during use (gparted)
There's still somehow ne possibility the hard drive on:
500gb Linux Mint
500gb Windows 10

oÄ to partition?

Thank you

Yes, you can do that with gparted too.

Right click on the existing partition and then select "Resize / Move". Then create the second partition and leave it later to the Windows installer.

Very important: back up data before tinkering with the partitions. That can always go wrong and there's no undo.

Yes, you can use a live distribution that Gparted brings. (This example: https://gparted.org/livecd.php) But make a backup before!

Yes, it does not work. That's exactly what I wanted to do. Can't resize the partition. Minimum partition size 1TB and maximum PG also 1TB. If I change that, the button remains greyed out. I think I'll simply have to force Shell.

Do not do anything stupid! Do not force! That goes wrong!

I have not quite thought: You're on the system. * Facepalm *

Take the installation media and boot.

Then go into gparted and unmount the partition.

Then you can resize.

Well, a bad OS would not be bad either. Have all the important files anyway in Git Repos. I'll do it then, thank you.

Stupidly, of course, the hard drive can't repartition during use (gparted)

Then start a live version of CD / DVD (USB and you can already scale down partitions and create new ones (if there are not already 4 MBR partitions)

After that you will have to edit the / etc / fstab because the UUIDs of the partitions will have changed and reinstall GRUB (also with the live system)
