I have a problem with installation of android x 86 on Acer Aspire V3-731. I have ready installed Windows 8.1 and Linux Mint. I have one disk (sda) with 14gb of free space in partition sda11. So I've downloaded .iso of android x86 i doing the bootable usb with unetbootin. I reboot laptop and I chose a Legacy Bios because in Uefi pendrive doesn't boot. I selected install android x86 to harddisk and i saw an error: GPT[...]Use GNU Parted. So i trying to installed android in other pendrive, I selected pendrive, formate to fat32 and installed android, .iso image and I skipped question of installed grub but system doesn't work after reboot. What do i do? When i select to install grub and android in pendrive, i substitute linux/windows grub? It doesn't work because Linux and Windows working under Uefi?
