Sacha,
Let's try deleting the erroneous boot entries which are pointing to a non-existent device.
The statutory warning applies! Before modifying the boot configuration, please backup your system image (the OS and boot partitions) to an external hard drive using Macrium Reflect Free edition.
From Admin Command Prompt, run:
- bcdedit /export c:\boot_config_backup.bcd
- bcdedit /delete {9649d88d-4b28-11ed-8001-6d7368757261}
- bcdedit /delete {4069d4e4-2920-11ed-be4c-a85e45d0a878}
Then, run these commands and post the output here:
- bcdedit /enum All
- bcdedit /enum All -v
