I just setup my HP Notebook with 2 instances of Windows 10, installed on a single drive, and using UEFI style dual boot (i.e.: the bootloader starts that blue option screen letting me choose between the two instances, as opposed to the classic black/white BIOS type screen). Both Win10 instances are booting and working fine, so I could be happy with the result.
The weird thing is: the 1st instance ("Windows 10 MAIN") boots blazingly fast, and directly into the windows login screen after selecting it at the bootloader screen.
The 2nd instance ("Windows 10 MUSIC") though apparently does a complete reboot, this time without presenting the UEFI dual boot selection screen. Instead, after a (short) while, it finally gets to the "Windows 10 MUSIC" login screen. From then on everything appears to be normal. So this is more a curiosity-type question:
is this just the normal / weird Windows way, or did something go wrong during the setup?
--- update ---
maybe it helps explaining how I set this system up:
- installed Windows 10 MAIN to a previously wiped SSD; set the partition size to ~190 GB. The installation created the necessary additional partitions, the rest of the drive remained untouched
- booted into Windows 10 MAIN and changed the "display title" for the future selection menu using bcdedit
- rebooted to the setup image; created a fresh partition of ~150 GB, installed "Windows 10 MUSIC" to that partition
- booted into Windows 10 MUSIC and changed the "display title" for the future selection menu using bcdedit
Later on today I'll post a screenshot of a bcdedit /enum
