Win7 to Win 10 Upgrade - No bootable media after final reboot into new Windows 10.
1. Windows 7 - boots up fine
2. Insert Windows 10 USB and run upgrade from Win 7 Desktop
3. Windows 10 Upgrade seems to go just fine.
4. As the system reboots into what should be the 1st boot into Windows 10, I get a NO BOOTABLE MEDIA message.
** Drive (SSD) IS VISIBLE in BIOS in the Hard Drives area
*** Drive is NOT VISIBLE (but used to be) in the BOOT MENU
Seems like I need to do something to the boot sector.
I've had this happen several times now on various systems.
