So my friend have a really old laptop it got so slow it is unworkable on, I suggested him to install Ubuntu and remove Windows 10 which was installed. I was a supervisor of the process although it is my first time "installing" Linux, but I have a high technical knowledge. the problem start when my friend have 1 HDD drive with 3 partitions and all are MBR and NTFS format. he have data on D:\ and E:\ so we formatted just the C:\ (WinOS) and after problems and struggles we installed it with Grub and it boots very well. Now we have the problem of the D:\ and E:\ drives loading on read-only because we haven't disabled fast startup on Windows before uninstalling it...
Edit: not long after we tried booting into windows with a CD and then tried to turn off hibernation options using the installation cmd, it didn't work as it can't be configured from within the installer, my friend booted into ubuntu did some suggested updates (by the Ubuntu OS) and restarted and for some unknown reasons, they allowed for writing on them along the reading allowed before.
