[SOLVED] laptop starts from wrong drive

[HalalMonke]

My laptop tries to start from the wrong drive at startup which leads to it going into windows automatic repair mode since windows isnt installed on that drive, how do I make it start from the other drive that windows is installed on, I cant open up my laptop to disconnect the hard drive because I dont have the tools for it and im too scared that I might accidentally break it. Is there a way to make it start from the other drive without removing the one it tries starting up on.

i think i might see a problem now that i look at it closely, it has an efi system partition

Have windows installation media prepared.
If you don't have it, then make one.
It will be necessary, if something goes wrong.

When you have it, test if you can boot from it.
After that delete EFI system partition on 1TB drive.

The one without windows. Did it previously have windows on it? If so, then that's prob the issue. You may have physically deleted the files on the old drive, but left the boot partition behind. So your PC will try to boot to that drive, but without Windows install on it, it won't boot.

I moved every partition from the old one to the new one using macrium reflect. It did not have windows before on it. I think macrium only copied everything from it to the new drive.

How do i delete the partition?

Execute from elevated command prompt:

diskpart​

list disk​

select disk 1​

(select 1TB disk)​

list partition​

select partition 1​

(select 100MB EFI system partition)​

delete partition override​

list partition​

select partition 1​

(select 100MB EFI system partition)​

delete partition override​

i just did that and my computer goes to automatic repair without an option to safe boot or even reinstall windows using cloud/local. I cant even mqnually start up using my new drive

This is, where you boot from previously prepared windows installation media.
Press Shift+F10 to open command prompt and execute

diskpart ​

list disk​

list partition​

list volume​

Generally you have to find drive letter for windows partition.
list volume command would show you drive letters.
Find drive letter for 476GB partition. It will not necessary be letter C: in recovery environment.
I'll assume it's letter G: .
Then execute following, to fix bootloader (replace letter G: it with actual letter, you got from list volume command) :

bcdboot G:\windows​
