I have a Acer Aspire ZC-606 and it's not boot. When I try, it show Acer logo and don't go far. It show "insert bootable..." . I check in BIOS the order and it is HDD first nad CD second. I haven't chance to make a choice like "rescue or restaure or else. In BIOS I can make the choice to boot on Windows 7 or 8.1 but it's not booting with one or the other. I think it's need an reinstall disk but I don't have this disk and I can't have access to partitions. Do I can have a reinstall disk ? Is it free or I have to buy ? Please help me.
