Can install media make a disk bootable?

I have a problem. I have a PC with a 240 GB SSD and a 2 TB SSD and two 4 TB HDD.
The UEFI bios only shows the 240 ssd as bootable after a clean reinstall of win 11 (with USB media) even though I installed win 11 home on the 2TB ssd.
If I boot on it, it says a file file missing, and it gives me option to choose another OS, I then choose win 11, and it boots fine into my 2 TB SSD.
Now it has started bitlocking all my drives except the 240 GB, that's apparently default in 24H2.
That's going to take forever and I would like this problem fixed, so I have some questions about my options:
Is it safe to restart the PC, go into bios as disable the 240 SSD, boot onto the install media, choose repair?
Will that repair mess up the bitlocking in progress? Will repairing even be able to move the boot to my 2TB drive or am I forced to use some commandline?

  • Your UEFI BIOS is recognizing only the 240GB SSD as bootable after reinstalling Windows 11. This is a common scenario, especially if the system boot manager is installed on the small SSD. The boot manager might not be configured correctly to boot from the 2TB SSD where your Windows installation resides.
