I installed Ubuntu dual-boot in my PC alongside Windows 10. Before installing, i had shrunk my 1TB hard drive and left 200 GB for Ubuntu installation. The installation went fine, but after booting up Windows, I see in disk management, that a new logical drive had appeared, which i did not create, having 512 MB size...Can i safely delete the new drive?

    Might be EFI or /boot (=Do not delete!!) Check the disk manager. – pLumo Nov 20 '20 at 11:21

    What is E:? That is not a name Ubuntu uses. Are you expecting us to understand what "disk management" is? You are asking it from a windows perspective... Please use gparted and other Linux based tools to explain this. Ubuntu will tell you exactly what partitions are used for. Windows does not. – Rinzwind Nov 20 '20 at 11:48
  • Sorry I messed up! I am a newbie and didn't really think I would receive replies...so I deleted it as in windows the disk was showing empty...but when I boot my pc now, grub rescue comes up...I think I might have deleted the /boot partition as @pLumo suggested...please help me , how to fix it??? Please... – Srijan Mukherjee Nov 20 '20 at 12:07
  • Will just reinstalling Ubuntu fix it? – Srijan Mukherjee Nov 20 '20 at 12:18
  • You don't need to reinstall Ubuntu, just reinstall grub. – karel Nov 20 '20 at 12:30
  • Ok, but actually I am not familiar with the process of reinstalling grub, but I do know how to reinstall Ubuntu....and since it was a fresh install anyway, I don't have any important files....will reinstalling Ubuntu fix it? If it can't, then can you help me with reinstalling grub? Btw, thanks a lot for it help – Srijan Mukherjee Nov 20 '20 at 12:35

  • Best now to start creating good backups of both Windows & Ubuntu data. Easy to reinstall Ubuntu, but you need your data & settings from /home so you do not have to totally redo them. http://askubuntu.com/questions/2596/comparison-of-backup-tools & https://help.ubuntu.com/community/BackupYourSystem & https://ubuntuforums.org/showthread.php?t=2436006 – oldfred Nov 20 '20 at 14:51
  • Thank you! I will surely give it a try! – Srijan Mukherjee Nov 21 '20 at 04:08

Do not delete! It contains grub config files! Deleting will cause grub bootloader to fail to start!
