Win7 + Lubuntu 16.04 (via USB Memory stick) did not finish installing and when rebooted: boots only into Ubuntu. As expected, Lubuntu was installed in the second HDD partition: Windows partition shrunk to 40GB and was unformatted for Lubuntu.
This is the screenshot of where installation froze:
Is it possible to command the USB install to continue setting up and finish the dual boot mecahnism?
update-initramfs -u
in addition to update-grub, because my guess is that it got stuck at creating the initrd. This is all guesswork though, you should provide installation logs if you expect accurate answers. – LiveWireBT Nov 12 '16 at 02:55
