unknown file system error?UpdateCancelAnswer Wiki10 Answers Amit Kumar Padal, A Fellow TradeviserUpdated 13w agoI faced the same problem a week back when my sister got a HP laptop which came with Windows 8.1 & Ubuntu preloaded. The Windows was partitioned with 320 GB of unpartioned drive and the rest was allocated for Ubuntu. All I did was partioning my hard-disk in Windows. Then once I restarted my laptop it said "unknown filesystem" "Grub Rescue" & I couldn’t get any further.After struggling for hours I could fix the boot-loader problem. Here is what I did:-Stop panicking, you didn’t loose your data.-Switch on the laptop, wait till you get the Grub Rescue Screen.-Type the following commandslsIt will show you a list of partions you have made.You will get something like this (hd0),(hd0,msdos1)(hd0,msdos2)(hd0,msdos4)You need to find which drive is your Ubuntu root for which type the following:set prefix= (hd0,msdos1)/boot/grubIf it’s not the root drive you will get an error message "unknown filesystem". In that case try the same command with the next partion, ex: set prefix=(hd0,msdos2)/boot/grubIf you are not getting an error: Congrats, you have found your root drive. You can proceed to the next command after that:set prefix=(hd0,msdos1)/boot/grubinsmod normalnormalYour PC will now boot successfully. Now select Ubuntu & login.Open Terminal( Ctr+Alt+T or use the search)sudo update-grubsudo grub-install /dev/sdaNow the bootloader error is fixed you should be able to boot your laptop normally & even your data is intact.If sudo update-grub didn't work, type sudo grub-update54.1k Views · View UpvotesRelated QuestionsMore Answers BelowHow do I fix unknown file system grub error?How do I boot a system after grub rescue error, unfortunately unknown filesystem says when I run
