ok so i had windows 8,
i wanted to revert to windows 7,
so i was deleting old system files,i found my linux.iso,
i wanted to dual boot, so i installed it,
turns out i forgot to set the partitions and it wiped everything, so now basically,
1.i dont have any data
2.my NTFS partition is gone
3.so now i tried to reboot with a windows 7 bootable disk, but when i click install it says "cd/dvd drivers not found please click on directory"
i tried inserting the motherboard cd but in vain...
