Can I unallocate these & linux be fine?

SDA1-3? I have a feeling I can just want to be sure.

Definitely NOT /dev/sda1 (!)
It appears to be part of your system and is therefore absolutely necessary.

Only you know what is on /dev/sda2 and /dev/sda3 and whether you need what is presently there.

If you delete them while the entries for them are still in /etc/fstab you will have problems booting the system.
It will either hang for a long time or not boot at all.
Check and edit /etc/fstab as well when you decide that you are going to remove these partitions.

Have a backup!

Absolutely not, sda1 is your linux’s (and your (former) win efi partition), don’t mess with it. Sda2/3 look like win partitions, the sda2 fat may be some win recovery and sda3 the win ā€˜c-drive’, you have to decide if you still need those partitions and the data on them. If you dual-boot with win don’t touch anything.

Just to be clear, ā€˜unallocated’ in gparted speak means ā€˜blank’, ā€˜empty’, ā€˜wiped’.

ā€˜Can I unallocate these’ is misleading since there is no ā€˜unallocate’ button. You can, however, delete those partitions which will then show ā€˜unallocated space’ were they have been before.

Sorry only meant SDA2-3 wasn’t all the way awake. SDA2/3 is a Win install that won’t boot up right, so SDA4 will stay SDA4 I want to make 2/3 into 1, that will no screw up Linux right?after I get rid of 2/3.This is my fstab.
!# /etc/fstab: static file system information.

Use ā€˜blkid’ to print the universally unique identifier for a device; this may

be used with UUID= as a more robust way to name devices that works even if

disks are added and removed. See fstab(5).

UUID=6DB0-0A0F /boot/efi vfat umask=0077 0 2
UUID=0647dad9-3687-4eba-8d09-acc5ce30021d / ext4 defaults,noatime 0 1
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0

Just lloks like Linux is in fstaab.

Grubs list doesn’t have them, just the MB boot menu.

In this case, you should be able to safely remove those and re-allocate the space for data — perhaps include a swap partition as well?

It should not - but it might.
It can become problematic should anything fail during the operation - which will take a long time.
Nothing unsurmountable - but some work and knowledge of what you are doing is better …
It involves moving the start of that partition - expanding it ā€œto the leftā€.
If you have everything backed up … you can try.
It’ll probably work ok. but better safe than sorry, no?

I’m afraid I misinterpreted things; I thought he meant to create one new partition in the free space.

Indeed, messing with an existing / partition is not without its risks. For example, a power outage during the process will really screw things up.

Using gparted, you should delete sda2 & sda3. Gparted then should show you a single area (~250 Mb) that you could totally use to create a partition.
Do not touch sda1, do not try to use the unallocated area before it : 1 Mb lost : not a real problem .
And do not touch sda4, of course !
What is the content of /etc/fstab ?

… but (!)
he want’s to expand /dev/sda4 - in the direction towards sda1, to the left

Not a problem - but having a backup is (almost) mandatory when doing this.

OK but I don’t see the advantage of expanding sda4 as compared to the risks of moving its beginning and so its content. Adding a new partition in fstab is easy, and having a separate data partition is preferable. But it’s only my opinion.

We are on the same page.
But that is what he want’s to do … :man_shrugging:

I’d have a backup.
Then I’d completely recreate the partition layout as I want it
and then replay from backup after having mounted the partitions in order
and adapted /etc/fstab

Much cleaner and probably even faster.

Love it or Hate it, still have to have Windows for some games. I get this when I try to open it. Fat32 is the FS.
