Yes, pick option #2.

Is the next following step the right one?:
Leave sda1 and sda2 and sda5;
Remove sda3 and sda4;
Use sda6 to install ubuntu;

Will this result in working windows alongside working ubuntu?

And also, i tried to do the above mentioned,
as I click "Install Now" the following message appears:
Heading: No root file system
Message: No root file system is defined. Please correct this from the partitioning menu.

I'm not sure what this means :/

It means you must set /dev/sda6 mount point as root, ie "/"
(you can do this in the partitioning menu.)

Edit: not sure about sda3 and sda4, but you'll be able to remove them later, so no need to hurry.

Im really close to replace windows entirely with ubuntu, after installing ubuntu when I turn on my laptop, there is just a short white line flashing on a black screen. If I type, nothing happens, i guess something is wrong with the boot system?

Do you have grub just after powering on? And did you make a boot-repair disk?

I dont think so, i just see the acer logo with f2 and f12 options and then the black screen I described, the disk is downloading still, but I'll have it soon.

Edit: should i use the disk as soon as I get it?

Yes, and if it's only a boot problem (hopefully), you should be able to fix it.

I tried the disk a few times and didn't get anywhere, I'm abit confused what to try next

Could you boot from the repair-disk? If yes what happened? The more details you provide every time, the easier it is to find out what's going wrong.

Awesome, I made some progress..

I booted of the Boot-Repair-CD and boot repair ran. After going in circles I got to a message that said I should change the bios boot settings and then make a live usb of the boot repair cd. I did this and it repaired GURB. I restarted without any CD's or USB live and now I'm looking at GNU GURB 2.02.

But I don't see Windows, There is 5 options:
Ubuntu
Advanced options for Ubuntu
efi/EFI/ubuntu/MokManager.efi
EFI/ubuntu/MokManager.efi
System setup

Is there still a chance to recover windows as a option to boot?

Edit:
There is 5 options:
Ubuntu - seems to work fine
Advanced options for Ubuntu - gives 4 sub options
efi/EFI/ubuntu/MokManager.efi - gives error: file 'efi/EFI...' not found
EFI/ubuntu/MokManager.efi - gives /EndEntre file path: /ACPI... error:cannot load image.
System setup - open Bios settings

Did you remove any windows partitions (sda3 or sda4) ?

Anyways, you can now boot Ubuntu, then install boot-info-script and provide the output. You can also see what partitions you have on disk with your file browser and/or gparted.

Again, try to provide as much info as possible.

Attached is the new RESULT.txt from boot-info-script.

I did remove sda3 and sda4 right before the Edit part of your reply showed up, do you think that’s the problem?

Sorry about the lack in providing of info, I'll try to do better as I become less of a newbie

Not totally sure, but you previously had this:
and now, you have this:
So, yes, it could be the reason.

You could boot from a windows 7 disk (if you have one) and try to repair windows start up, then use your boot-repair-disk to reconfig grub.

There is also 'testdisk' (sudo apt-get install testdisk) for partition recovery, so it could be worth giving it a try, although it's from command line and not that easy to use.

So, have you a windows 7 disk?

I greatly suggest before doing any commands that write to partitions, that you take a half hour and look to see what would be critical to lose.
Getting back windows would be a huge pain (thanks to m$..) but getting back unique data is even more unlikely should you make a wrong move.

Back it up! Don't just back up everything, select and choose. Keep it under 5gb and upload it to Google Drive or Mega or something.

I have a Windows 7 disk and did the start-up repair. Then the next time I turned on my PC I booted in Windows 8. Then I went to the bios settings and changed Ubuntu above Windows in start-up order, Now I'm in ubuntu and I think I need to do the Boot Repair Disk again?

Also: When Ubuntu loads, the following flashes, but then after ubuntu starts and everything seems to be in order.

Any idea what this means?

Edit:

Sorry the should be a
