How to reconfigure, move, and not break Dual-Boot?

Question

linux

Hello everyone, I decided to tidy up my PC, I need advice on Grub and migrations.

Now the situation is this: the laptop has 2 256GB Samsung EVO SSDs, divided as follows. The first is fully occupied by Windows 10, formatted, of course, in NTFS, encrypted with VeraCrypt. The second is broken like this: 8gb - SWAP (ext4), 64gb - Ubuntu (ext4), everything else is storage available from under both systems (therefore NTFS). Configured dual boot in grub.

What needs to be done: now I’m not satisfied with ecryptfs, which is crookedly configured in ubuntu, non-working swap (and at the same time hibernation) and lack of space on the system disk with Linux.

In connection with this, I want to do the following:
1. Reinstall Ubuntu, because. infuriates crooked encryption and swap + there are other clumsiness, tk. learned in the process.
2. Expand the system partition. 64GB was not enough, now I will select 128.
3. Enable hardware encryption instead of software encryption. As far as I understand, my disk supports it, I was going to turn it on according to this instruction: https://www.dell.com/support/article/ru-ua/sln3086...
4. Swap disks (m.2) on the motherboard in places , because one slot (in which there is a disk with Windows) on my computer is faster than the second one and disks that have the same speed operate at different speeds.

How can I do all this and not break grub and dual boot at the same time? How to migrate to a new Linux? Suddenly there will be advice from the experienced. When you write what to do, please write specific steps and commands or give links to instructions, because I still don’t know how to do a lot in Linux (unfortunately), despite my six months of experience using it. Thank you!

You won't break a dual boot. All you need to do is save all your data from the disk where Linux is installed and repartition the disk as you need and install the new system. During installation, Grub will detect your second Windows drive.
