Hello!, im having some trouble on doing this.
I have a Virtual box NT4 machine, i installed uniata, and the universal graphics driver. Well the problem is, i have in the netbook, Windows xp and windows 8.1 in dual boot, the boot partition is on FAT32 format (i installed the fat32 driver for nt4, also have the boot files from xp).
How i make a partition bootable? Boot files are on the active partition that has the xp and 8.1 boot files, but the partition that has NT4 isnt bootable,
