Hi,
I use a pretty recent Intel Haswell notebook (Acer Aspire V5-573G: http://www.notebookcheck.net/Review-Ace ... 264.0.html )
I used UEFI right from the start. I have a working linux mint, Intel's Android (https://01.org/android-ia) and Windows for gaming. Running fine with GRUB2.
I tried putting Mageia onto an USB stick, following the instruction about UEFI on the wiki. I did partition the stick with GPT, format it FAT32, label the stick MGALIVE, mount the .iso, cp the iso contents over to the stick.
I can boot the stick and get the initial menu to choose what mode to boot. After choosing, the screen turns black, and nothing happens anymore. I tried both the installer .iso and the LIVE .iso, trying all boot-menu-items that make sense.
What might be special about this machine is the fact, that I use 19 Partitions. sda1 to sda19. Android is the main reason for this. Seperating home, develop and other partitions the secondary reason.
Solving this problem would be appreciated. This OS looks great and I sure want to take a look, and probably use it as my daily driver.
