Howdy everyone! Anyone on Earth can tell my WHY-oh-WHYYY I had to enable UEFI in my bios to be able to install Windows 8.1 with update in my pc? D510Mo using na hdd from acer notebook. Removed the partition using diskpart, cleaned it... no joy! Windows setup says it couldn't install in that disk and I had to check the install logs (where the hell those logs are saved?) Anyone knows why? I'm missing something? There where no GPT partition on disc, no nothing... Thanks in advance!
