I have been trying to get this working since quite a few days, reading everything I find which I think is related with my issue but no luck so far.
- I have Windows 7 64-bit installed in an SSD M.2 format (Disk 1 on the image, sdb1 in Mint). It is a bootable partition as you can see.
- I have grub plus Linux Mint and other data partitions in an HDD (Disk 0 on the image, sdaX in Mint).
- I have used disk2VHD to create an image of W7.
However, when I try to start W7 with VirtualBox in Mint (similar to Ubuntu for those who don't know), I get the blue screen with error code STOP 0x0000007B (not boot found). But in principle, W7 partition is bootable. If I disable the HDD, W7 starts automatically.
I have tried several controller configurations (PIIX3, PIIX4, AHCI, NVMe,...) enabling the Solid-state Drive but no luck either. With the first three, blue screen and then Windows starts on recovery mode, but with NVMe it cannot even find the partition where to boot from.
I have also tried to fix Windows using Windows recovery disk but not even like this.
Anyone with an idea about what might be happening?
Many thanks!
