I’ve recently completed tinkering my new pc(motherboard ASUS z77 with UEFI BIOS) and unfortunately not everything works quite well.<\/p>\n

After installing windows 7 ultimate on a single primary partition(SATA drive) I decided to allocate one more logical partition for additional needs. When I tried doing it with the manager – it said that it couldn’t allocate requested size even though I certainly asked for much less than it was available.<\/p>\n

I thought that it might have been a windows issue and proceded to installing Ubuntu 12.10 x64. When the graphical interface loaded it showed me a message stating that it can’t find any other operating system on the drive. When I used custom partioning option it showed me none of my current partions(including that with windows). However, when I boot with “Try Ubuntu” feature it does find them ! I find it weird though.<\/p>\n

Here’s what the console present me with:<\/p>\n

I also tried creating partitions from disk utility which results in error:  ,<\/p>\n
<\/p>\n
\n

Here’s what I get when I try to install the system<\/p>\n

P.S. It’s strange that I even can’t create any more partitions neither with disk-utility nor with windows 7 native tools<\/p>\n","protected":false},"excerpt":{"rendered":"
