On my netbook (HP mini 110) there was a LUBUNTU (do not remember which one) operating system. I Tried to install Windows XP.

The hard disk format was EXT4. To change the hard disk format from ext4 to ntfs I did this.

1) Downloaded and extracted .iso file into USB using rufus ,

2) Ran the Lubuntu ISO from usb,

3) Ran the GParted program and changed the main hard disk to ntfs type.

I then burned the Windows XP ISO to usb again, Changed boot priority (made usb first readable drive)

The problem is that when I turn on the computer, after a few seconds, this error occurred:

error: unknown filesystem.

Entering rescue mode...

grub rescue>

Nothing about WINDOWS is appearing.


I had experienced the same error after I deleted the partition with Ubuntu while dual booting my PC. This error happens because the grub cannot find the right Ubuntu partition when you load the computer. This happens when you format the partition wrong.

To fix this try the following:

  1. Write the Ubuntu 16.04 ISO to a file.

  2. Boot it up into the installation menu.

  3. Choose the 'Try Ubuntu' button. (NOT THE INSTALL BUTTON)

  4. Open the terminal.

  5. Type in sudo apt-get purge grub* && sudo apt-get autoremove

  6. Reboot the system to then install your OS (Windows XP).

I hope this works :D

  • That error message is the one that I had received, and this seemed to clear it, but I do not quite understand how you are trying to install Windows and what the current state of your computer is (Does it currently have an OS installed), Sorry :D. – Intel_I7_Inside Aug 11 '16 at 17:41
