How to boot to second windows drive

Question

I got 2 ssds in my system. Lets call the first one 'a' - it has my original system. The other one is 'b' and i just installed the system on it. The problem is, I can't boot into my disk 'b'. BIOS only shows "windows boot manager" in the boot order, and the menu that appears after restarting while holding shift has no option to change boot. Also the system on disk 'b' couldn't connect to the internet.

Answer 1

It displays this error, which in english would be "We were unable to create a new partition or locate an existing one. For more information, see Windows Installer log files" ![](https://learn-attachment.microsoft.com/api/attachments/8d8220c6-2f44-4423-addf-241ca22283b7?platform=QnA

Answer 2

Thanks for the info.

In this case we will need to format the disk using the diskpart command.

The image shows that there are other disks connected to your motherboard, I recommend that for safety you remove them all and leave only this one, follow the procedure below.

First start the Windows installation and go to the screen to select the installation location, after that perform the procedure below.

1. Press SHIFT+F10 to open the command prompt;
2. Type the commands below and at the end of each one press Enter:

diskpart

list disk

select disk 0 (Change the number 0 by the number of the disk where you want to install Windows as listed in the previous command)

clean

create partition primary

exit

exit

3. Click Update and you will see that a new partition has been created on the disk;
4. Select the partition and proceed with Windows installation.

Answer 3

I have used the commands, now there is a different error: "Windows cannot be installed on this drive. The selected disk contains the MBR partition table. On EFI systems, Windows can only be installed to GPT disks!"

Answer 4

Thanks for the information, we will need to convert it then.

Run the commands this way.

1. Press SHIFT+F10 to open the command prompt;
2. Type the commands below and at the end of each one press Enter:

diskpart

list disk

select disk 0 (Change the number 0 by the number of the disk where you want to install Windows as listed in the previous command)

clean

convert gpt

exit

exit

3. Probably just the unallocated space, click the New button, the partition will be created, click next and check if the installation proceeds.

Answer 5

I have succesfully installed windows 10 on disk b, the network card drivers are working. Now how can I make sure that the system will boot correctly?
