I'm using Debian and Windows 7 located on one HDD, in dual boot. Windows 7 had two partitions (system partition C: and general-use partition G:). Recently I've cut the G partition in size and created new partition F in emptied disk space. I'm pretty sure there was no reboot after that: laptop was on/off in sleep mode for few days. Now after what may be first reboot since partitioning, I get grub error: unknown filesystem in Rescue Mode. Could those changes in partition be the source of error? How to restore Grub to working state? (Preferably without losing the data from HDD)


  • What file system did this new partition have exactly? Does Debian have NTFS support? – Ramhound Apr 22 '14 at 14:41
  • New partition is supposedly nfts, though I'm not 100 percent sure now. I don't know if and how Debian supports NFTS, but I guess it does on some level; I always could access files from Win7 NFTS partitions under Debian, if that's the case. – Ponyman Apr 22 '14 at 18:15
  • You need to be sure what file system is being used and if its supported on Debian these are not tall tasks I ask of you. – Ramhound Apr 22 '14 at 18:30
  • Using grub to bootstrap windows? Trying to think about your solution seriously gives me heart burn. Not a solution, but I would delete your debian partition and format it with empty NTFS partition that I would use to store my debian virtual machine image for Virtual Box and use both at the same time! :) – jredd Aug 15 '14 at 15:49
