I bought my Asus in 2012. It came to me with FreeDOS. I installed Windows 7 and a few days ago I wanted to install Ubuntu 12.04.4 to my pc alongside Windows 7.
But I read about UEFI about problem which happens to new pcs. I have C, D, E partitions on my pc. Windows is in C. I wanted to install Ubuntu to E. The E partition has 58 GB. And 50 GB of it is empty.
And I parted that 50 GB to 30 GB. And in my boot menu there is something like that.
- boot option #1:UEFI: DVDRAM
- boot option #2:ht sata
- boot option #3:DVDRAM
I booted my pc using 3rd option thinking that my system is not in UEFI mode. There was no any problem. I chose something else. And the disk partitions window has come. I knew my C, D. I did not touch them , But there also to partitons which are sda2 which is double clickable. The other one says that it can not be used and I chose the sda2 and formatted it in ext4 But swap area is not created. And I continued whithout formatting the swap area. But my Ubuntu and Windows works well. Only one problem my E partition has dissapeared. It is not important but I created different place for Ubuntu. Why is this happening?
