Android-x86, can't install any app
It would seem that the cause is the ext3 partition.

The problem with this OS is that if you install it on a FAT32/ext4 partition, the grub doesn't work to dual boot with Windows, and if you install in NTFS, it dual boots but you boot without any free space on the OS

So yeah, rip lol
