Gparted not allowing me to partition sda3

id flag

Installed GParted on my day old Ubuntu desktop. Ubuntu was installed in UEFI mode. I want to dual boot win10 so I decided to install GParted to make a partition.

Here's what my GParted screen looks like:

enter image description here

It should be noted that there were no mounted files to begin with. This was the same screen I saw at the very beginning.

When I right clicked on the sda3 partition (the one I wanted to make a partition from), it wouldn't allow me to resize the partition (no error message came up, the "resize" button was just unfilled and nothing happened when I pressed it).

What should I do to make a partition?

/dev/sda4 is allready a partition. What do you want to do with it ?

With UEFI, you have to also install Windows in UEFI mode if drive is gpt. And if UEFI it should be gpt partitioned. Windows also in UEFI mode wants lots of partitions, so just create unallocated space with the LVM tools as posted in answer.https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/configure-uefigpt-based-hard-drive-partitions?view=windows-11#RecommendedPartitionConfigurations

According to your screenshot /dev/sda3 is an encrypted partition. GParted cannot resize encrypted partitions on its own. See https://help.ubuntu.com/community/ResizeEncryptedPartitions for instructions how to do it.

Is there something like Gparted that would recognize the encrypted partition's true size, despite it being an lvm partition?

Not that I know of.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
