how to install windows 10 without losing my ubuntu data ?

Because Windows uses the NTFS file system and Linux uses the ext4 file system you'll have to copy/backup the data somewhere before re-installing.

Your options are:

  • Upload to the cloud such as Google Drive; or

  • Copy data to a USB disk or another external drive; or

  • Use the Live USB installer to resize your disk and create an extra NTFS or FAT32 partition and move your data to that partition and be careful not to allow Windows to format it when installing

  • Yes, I am backing up data is the one and only way, but I am looking for a way other than backing up data because I don't have a flashdisk. – Aji Dwi Prasetio Feb 14 at 8:24
  • Your only option is to use the cloud – Kristopher Ives Feb 14 at 8:27
  • I feel the third option is best. Create a partition and move your data there. So later you can directly use it from Windows. – Jrct Feb 14 at 8:29
  • so i cant copy data from ext4 file system to NTFS file system ? – Aji Dwi Prasetio Feb 14 at 8:29
