Windows 10: Accidentally Dual-boot my pc, now the Windows 10 on my hdd is not detectable when I unplug...

Hello, I've recently fresh installed the latest Windows 10, but during the install I forgot I still had my portable Windows 7 on my 32GB Flash Drive. Now my PC detects my flash drive as a bootable device and startup at Choose Operating System. Here is the problem, when I remove my Flash Drive with Win7 on it, my PC doesn't detect that my HDD has Windows 10 on it, only it recognize when I plug back the Flash Drive. I tried deleting the second OS on the msconfig, still nothing changed.

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

Hi Guys I got a HP 15 here that I have dual boot with Windows 10 and Windows 7. I recently bought an HDD Caddy that goes into the DVD drive, I have a SSD thats 128GB on it.


On windows 10, the hdd / caddy is not detected at all.
Another issue being if keep it connected turning the laptop on, it always goes into Windows 7 (no option to chose os/boot menu.
