It's not slow at all. You should try it.
I am running Microsoft Windows XP SP3 and Linux Lubuntu 17.10 on an ASUS Eee PC 1005HA netbook. I would like to install a third OS, Android-x86, to the hard drive, and for this purpose I freed around 10GB of space from the XP partition. However, there are already four primary partitions on the disk, and converting from MBR to GPT is not possible. Is there any way that I can make the installation to the hard disk rather than to a USB or an SD card?
