Hi! Back from a weekend of camping

In regards to the comments regarding no EFI System Partition or System Reserved Partition:

There won't be an EFI System Partition because the system is booting in Legacy BIOS mode.

A System Reserved Partition on a Legacy BIOS system is optional, although it is standard for there to be a separate System Reserved Partition. Many users in the past did not like having a separate System Reserved Partition, and they would delete them and then make their C: drive partition their system partition using the same commands I posted. If you want to create a System Reserved Partition on Disk 0 (the SSD) it is fairly easy to do. You would use MiniTool Partition Wizard to shrink C: drive by 100 MB-but put the empty 100 MB space at the front of C: drive (to the left of it) rather than the end (to the right). Once you have 100 MB empty space at the front of the disk (to the left of C: drive, the commands would be:

Code:

diskpart
select disk 0
create part pri
format fs=ntfs quick
assign letter=z
active
exit
bcdboot C:\Windows /s Z: /f BIOS
diskpart
select volume Z:
remove letter=z
exit
exit

There is a chance if one of the commands above failed, you would end up with a system that would not boot until you repaired it with a recovery drive, so I would just leave it alone.

What I would do with the second HDD is use Macrium Reflect Free to make an image of the E: drive partition saving it to the external hard drive. Then delete all the partitions in front of F: drive, and expand F: drive to fill all the empty space. Then you could always mount the image of E: drive from the external hard drive and copy out any data files you needed.

I appreciate your reply and welcome back!

Regarding my issue, I won't create System Reserved partition if it's optional, I just wanted to know if it's fine to run system without it, regarding the old HDD, I'm doing backups to my F: and USB drive, then I will go in Disk Management and run "Delete partition" for "System Reserved" partition and "E: drive" then I will select my F: drive and Extend the other 2 unallocated partitions to it, if that's what I should do please reply with your opinion, thank you once again!

I wouldn't use that software because at the moment I can't externally plug my new HDD in, after I'm done with manually backing important things from my E: partition, I will just delete it along with the System Reserved partition, after that I will psychically remove my old HDD, and mount my new 2TB HDD and just activate it in Disk Management

Delete all three partitions in front of F:, including the recovery partition. Be aware that native Windows tools such as Disk Management and diskpart cannot extend F: to the left (they can only extend a partition to the right). You will have to use a program such as Minitool Partition Wizard to extend the F: drive.

Why does that matter if in the end there will be only one partition?

Also, since I'm going to Delete all the partitions and not "Format" them, I will probably have "Extend" option in Disk Management but I still don't get what left and right has to do with the extending?

I would do the same thing from 1:45 that this guy did on the next video: YouTube

1. Delete volume
2. Delete partition
3. Select F: and click "Extend" and then just extend it with the 3 unallocated partitions that I previously deleted

Go ahead and try it. Neither Windows Disk Management nor diskpart will extend a volume to the left to fill empty space in front of it. Don't ask me why. I didn't write Windows. You have to use a third party program to do it.

Yeah I realized about what you were talking about, F: is the last partition on my HDD drive so if I delete others in front I won't be able to extend them into F: since it's the last one

It has to do with the master file table, I think. The master file table (MFT) is located at the beginning of a partition and contains all the entries for the files located in the partition. Extending a partition to the right (move the end of the partition), only requires a couple of entries to be changed in both the partition table at the front of the entire drive, and the entry in the MFT that defines the end of the partition. All of the locations of the existing files, however, stay the same - relative to the beginning of the partition which has not changed..

To move the front the of the partition to the left, however, the entire MFT must be moved to the new beginning of the partition, and all of the locations of files have to be updated because they are in a different position relative to the beginning of the partition. Microsoft just didn't want to deal with all that coding.

Basically, nothing in Windows, by itself, will allow you to change the starting location of a partition. If you want to move the starting position of a partition to either the left (extend) or the right (shrink), you have to use a third party partition program to do it. Windows, by itself, will only let you adjust the end of a partition.

You're right, I found this video on YouTube

Tomorrow I will download that third party program called MiniTool Partition Wizard and before I use it, I will delete all volumes & partitions on the left except the F: one and make them become "Unallocated" through the Disk Management

After that I will go inside that MiniTool Partition Wizard program and use the Extend function to turn all Unallocated space into F:

I will inform you about the outcome.

Sounds like the plan. Good luck! You can also delete the partitions in Minitool Partition Wizard as well. Don't forget to click the Apply button in Minitool!

Alright, thank you once again.

I seem to have fixed the problem, thank you once again @NavyLCDR
