Hey all, I was wondering if I could move unallocated space to the front of my boot drive and not have any issues. I have been having trouble getting mbr2gpt to work as I am getting this error "ValidateLayout: First partition too close to the beginning of the disk, Should start at offset 17408 or above, found at 4096" so I was thinking that if I move some unallocated space to the front of my boot drive this might solve the problem.

Pretty much I would be doing this:

using AOMEI Partition Assistant.


But before I go ahead and do it I would want to make sure that this would not cause any issues.
Thanks for the help!

How does a boot work?
It reads the first block of the boot device and transfers control to the boot loader.
If you try to manipulate this, all sorts of things can go wrong.

A ssd likes to start on a 4k boundary to be able to handle updates efficiently.
To see if this is your issue, run AS SSD, you should see in green a couple of lines indicating your ssd is set up properly.
Moving partitions around is risky. If something goes wrong (error in move process, power interruption), you'll loose data. Make a backup first.
Copying partition is safer. You don't loose data, if it goes wrong.

How much free/used space is in partition C: ?
If it was only half full, then you could
shrink it in half,​
make partition clone next to it and​
delete original partition.​
You'd have free space at the beginning of drive this way.

Thanks for the recommendation! Would I be able to do this in the windows disk management or would I have to use something like AOMEI Partition Assistance? Also is there any way you could list simple step-by-step directions of how to do this? I just wanna make sure I do things right and not mess anything up.
Again, thank you so much for the help!

Disk Management doesn't support copying partitions or moving partitions. It supports shrinking though.
I find Minitool Partition Wizard Free - quite useful for partition management operations.
Also is there any way you could list simple step-by-step directions of how to do this?
Step-by-step instructions to do what?
Shrink a partition? Right-click on a partition and choose "shrink".
Copy a partition? Right-click, choose "copy" and choose destination.
Delete a partition? Right-click and choose "delete".

I'm sure, you can figure it out.
