Thanks, Mahmoud. As you have replied in this thread rather than the separate more detailed one I posted, I'll follow up here. One suggestion and two questions.
The suggestion: to include prominently somewhere in the EasyBCD promotional documentation a clear statement that - at present - EasyBCD doesn't support direct booting into more than one Linux OS which uses GRUB2. Many Linux users like to run several distros, and most Linux distros I believe nowadays use GRUB2 bootloaders. It's obvious just from the latest couple of forum pages that I'm not the only member (Lilinux is another) who has come up against this limitation. It would have been good to have known this before starting...
Question 1: given this constraint, precisely how can it be overcome? The reply to Lilinux' post advised "adding the second Linux OS to the the first Linux OS' boot menu", but did not explain how. Maybe some expert Linux users know .... but I suspect many don't. The reply above also seems to suggest that for easyBCD to boot into more than one Linux (grub2) OS, somehow one has to insert the second Linux distro into the first one's GRUB2 menu, but doesn't say how.
Question 2: I posed this in my separate thread, and it is nice and simple: can EasyBCD manage one Linux distro which uses GRUB2 (eg Mint) and one which uses GRUB Legacy (eg PCLinuxOS), without special tweaking or linking the two Grubs together?
