That depends on your device uses legacy BIOS or
UEFI booting. I guess the old 1000HA uses legacy BIOS.
If so, just re-install Android-x86, and say yes
to these questions:
* Do you want to install boot loader GRUB?
* The installer found a Windows partition in /dev/xxx.
Do you want to create a boot item for Windows?
