You need(ed) to shrink /dev/sda2, then move it to the end of the disk to create space at the front, then grow /dev/sda1 to fill the gap between them that was created. Gparted can do everything in a single operation but clean installing is usually quicker
Yes and now it's kinda fresh and fast again. 
Yes.
Thanks for all your help anyway! I've learned something.
Yes.
Downloaded the generic and used the USB boot program but now it says that i should insert a proper boot device and doesbt boot from the USB.
One should not try or think that now i can do this on my own. Here is the result of me trying for myself.
My guess is that i will make a boot USB with the latest LibreELEC and start over. 
1.
2.
1) Set "Free space preceding (MiB)" to 782 on sda2.
2) Resize sda1 (+782).
3) Press the green hook button to execute both changes.
PS: Bonus: Set "Free space following (MiB)" to 0 on sda2. So you will not waste any disk space.
That worked, but the last PS did give me a sign saying (picture 1) and the picture 2 is showing how it is now.
What to do to remove unallocated space?
1.
2.
When i enetered 780 at free space following it worked.
782MiB.
While i was waiting for your reply i shrunk it 2 times a couple of mb. Here is the new size, Still 782?
Did you pressed that button after shrinking?
Oh yes!
Can you tell me which space and how much i am writing as a value to shrink. I must say i am not TO sure about what is what here.
Thanks. The menu looks OK, sda1 is un-mounted.
Shrink sda2, and then execute the shrinking by pressing big green hook button on the right.
After that try to resize sda1 again.
How much shall i shrink sda2?
I shrunk it to 35.95GB but still not able to resize SDA1.
Set GParted to English language (maybe restart necessary), and make a screenshot of the right-click-menu of sda1.
Ok i'll be back!
So here it is:
I have even tried to open a shell and entering the command unmount but it doesn't even know of that command.
Maybe sda1 is mounted, and that avoids resizing. Try to un-mount sda1 (right mouse click menu).
Tried that but there's only a ghosted option for mount.
1) Press the right mouse button over the sda2 table entry. Select "change size / displace".
2) Shrink size by 1024MiB.
3) Do step 1) for sda1.
4) Expand size by 1024MiB.
I've managed to shrink the sda2, but if you look at the picture it says on sda1 mini 242 and max 242. The + sign is ghosted and it can't be changed. I entered 1024 at the space where the 242 is but it just pops back to 242.
Yeah, see my PS above.
PS: If GiB is not available, set it to 1024 MiB.
Nope, still ghosted and can't be changed. Min 242 and max 242 it says.
Yeah, see my PS above.
Missed that one! Keep your fingers crossed! Here we go
Yes, that's the right menu.
1) Switch from MiB to GiB (forth menu entry).
2) Set the the second entry number to 1 (GiB).
As it is now i can't change sda1 it's ghosted. So my thought was if i shrink the sda2 a bit first? ...
There's no option for GB just MB and cylinder.
Expand the first partition (sda1) to 1GB. After that expand the user data partition (sda2) to the max.
Thanks, it is this one right?
I would just use GParted Live on USB
install it at some usb thumb drive (at windows with "rufus") and boot from it, then it starts a linux with gparted already preinstalled and auto opening
then you can easily resize your partitions
random video explains it (btw the text at the boot process is basically pressing "next next next"

Which one is it that i should change and how much?
Hi!
I'm not sure what to increse here.... please help
It's the last disc that i have connected to my pc.
EDITED: I can see now that i no longer have the resize option for this device, how come?
Or is it easier to just download the latest version and install it to the SSD?
But when i am looking at the download page there's several different for different hardware, whitch one should i use for my setup?
S1-AT5NM10E
The problem is that i don't have a mouse or keyboard to connect to the media player pc so my guess is that i can't install it from there.
Your initial problem was not with the total size of your SSD, but that older OpenELEC/LibreELEC versions created a rather small boot partition (/flash on the filesystem) which now became too small. Re-installing current LE (wiping your previous partitions) will fix that.
Current LibreELEC will work fine even on an 8GB SSD/SD-card/HDD, although I'd really recommend going for 32GB (or more) to have some spare room for larger movie libraries. If you want to store media files on your SSD/HDD/... you'll need a lot more space, of course.
so long,
Hias
Thanks for this glad news.
How can i re-install the current LE the easiest way? Should i reassembly my mediaplayer pc and do it from there or can i attache it to my pc and re-install the new LE from there so it creates this new size of the boot-partition?
HiassofT is right: If a too small OS partition is your problem, you don't need to buy an SSD. Just enlarge the OS partition with an appropriate tool like GParted. I suggest to give 1GB to the OS partition (LIBREELEC / OPENELEC), and assign the rest to the user data partition (STORAGE).
This is as i said to the answer before you! Thanks!
You have two choices:
a) Grow the boot partition by booting from another OS (e.g. Ubuntu LiveUSB) and using "gparted" to shrink and relocate the storage partition by 256MB so the boot partition can be made larger. This is not hard to do, but normally a very slow operation even with an SSD in the box.
b) Make a backup of the current storage partition, move it off-box, then clean install the same LE version to get the larger (512MB) boot partition and then restore the backup you took.
I'd personally take a third option:
c) Make a backup oof the current storage partition, move it off-box, then clean install the latest LE version and then unpack the backup and selectively restore DB files and config .. then reinstall add-ons at latest versions. In short, do a spring clean of the install, but keep the essentials from the old.
While you guys is answering i will attache the SSD to my pc and see if i can resize it from there. Thanks!
Sure, copy from HDD to SSD, and LE should work.
But how big SDD must i have is 128GB enough for the LibreELEC KODI 18.xx?
My plan was to just copy the harddrive from the old to the new,
Hi
A while ago, (months and months) i was trying to update my media PC player with libreELEC but it halted and said that i needed more space to be able to continue.
Now i have finaly taken out the harddrive but i forgot to see what version i had. I think it was 16.x something...
So for me to update and get a bigger one (the one inside is 40gb Intel SSD 2.5" drive) i have a ASUS S1-AT5NM10E Barebone for the task. Does any new SSD work?
Thanks in advanced!
