I received my UX31A to replace UX31E (thanks my boss) All the time I reinstall Win7 completely when I receive new computer, in general no problem but it's not the case here....
I tried to boot on an USB 3.0 key with Win7 Ultimate, when I booted on it (after some search in the Bios ... see later), there are no drive to select ("Select the drive to be installed") and install Win7. I boot on preinstall Win7 and I see the drive is GTP and not MBR. I used "EaseUs" (partition-tool.com) to convert to "basic MBR" and I install Win7
This morning I tried again, same key, .... same problem but the drive is in "MBR basic", no drive in the Win7 installer. It's may be because I entered in the Bios (F2) in Boot -> Boot Option there is only a #1 with [PO : ADATA XM11 256Mn], no USB key. To boot on USB key I did this : Boot -> HArd drive BBS Properties -> Boot Option #2 (Corsair Voyager 3.0)
How can I definitely solve this ? I'd like as UX31E (and previous laptop) an MBR, boot easily from USB or SSD, ... easily take me more time to search how install than install Win7
