bootloader

how do i transfer a bootloader to my C drive ?

[Vitalius]

Gonna need more information. What do you mean "bootloader"? GRUB? Some other bootloader?

Do you want to transfer it from another drive?

Are you also moving any other OS besides Windows to this "C Drive"?

Is it ok if the C Drive is lost? i.e. wiped/erased?

I had an old HDD(250gb) with windows 8.1 and some files i dont need . i recently build my new pc . my school gave me windows 10 education so i wanted to install that on my new 1TB drive. i installed windows on my 1tb drive. after i was done i plugged out that 250gb drive because i didnt need that anymore. But my pc didnt want to boot to windows without that 250gb drive

You can move or create the bootloader to the other disk with bcdboot and bcdedit; both are standard Windows tools.

 

The following example would put the bootloader on partition "D:" and set the system-partition to "C:"; given that D: is the hidden system partition, but you could also but the bootloader on your system partition.

bcdboot C:\windows /s D:
bcdedit /set {bootmgr} device partition=D:
bcdedit /set {default} device partition=C:
bcdedit /set {default} osdevice partition=C:

EDIT: Forgot to mention that you should mark the partition with the bootloader as active.

To access bcdboot and bcdedit, just boot from the WIndows 10 install ISO/USB/DIsc (however you have it), and click Repair Windows Install and then open Command Prompt.
