Restarting the Windows Boot Manager again.
Restarting the Windows Boot Manager again.
Hello everyone, I use three different operating systems on my drive. The issue is that after formatting the drive with the boot manager and setting everything up again, Windows won't add another boot manager, and I lose access to the boot screen. Previously, it worked when there were no installed OS dives and Windows would automatically add the boot manager to the second OS that was installed. Is there a method to reintegrate the boot manager once the drive is formatted and set up with a new OS?
It seems you're unsure about the details of your setup. From what you described, you had a partition for three operating systems, using Windows Boot Manager instead of Grub. You formatted the drive with all OSes, installed Windows as the sole OS, and then added another drive with a different OS that Windows no longer recognizes as bootable. Are you trying to clarify how this configuration works or troubleshoot something related?
You have three physical drives running different versions of W10. When you install a second Windows 10, the OS adds its boot manager to one drive. Formatting that drive for a clean install doesn’t update the boot manager, which is why it didn’t reinstall when you reformatted it. Previously, I had to format all drives again and reinstall Windows one by one. Now, with the Windows 10 boot manager on a drive that still has other OSes, it doesn’t reinstall itself.
Can you start from the newly installed Windows? Yes, the boot manager needs to be reinstalled. It’s missing entries for the other versions. You’ll need to add them yourself using BCDEDIT.
