What that means? You can't into deepin or what?

try do how us the grub cfg through grub.

Not that it's of much help, but with Deepin 15.1, the same thing happened to me after I had upgraded the Nvidia driver - next time I rebooted, I saw that initramfs terminal prompt.  My 'solution' was to reinstall an older Deepin backup I had made, then re-download up to half a gig of updates.  Yep, there's something flaky about this Deepin release, although 15.2 is perfect with me so far - seems much 'snappier' than 15.1 was too!
