I plan to install Ubuntu 12.04 on my new Samsung NP540 laptop. I do, however, have two concerns.
The first issue is that Samsung have decided that it is necessary to manipulate the BIOS in order to boot from USB or CD. The "OS Mode" has to be changed from UEFI OS to CSM OS in order to allow the USB to load.
I would like to keep Windows 8 and thus have a menu that allows me to boot into Windows or Ubuntu as I choose.
At "Installation Type" (when running the installation USB) the screen shows: "This computer currently has no detected operating systems" even though Windows 8 does exist. This presumably happens because I have selected the CSM OS.
The second point is about my partitions. I haven't needed to play around with partitions for some years and don't want to mess up the hard drive.
My partitions are:
/dev/sda 500GB [ATA hard drive]
partition type space used function
/sda1 ntfs 523MB 356MB recovery
/sda2 fat32 314MB 33MB EFI
/sda3 ? 134MB unknown ?
/sda4 ntfs 471834MB 35984MB c:\ drive (with Windows 8)
/sda5 ntfs 26226MB 25364MB recovery
/sda6 fat32 1073MB 740MB recovery
/dev/sdb 24GB [SSD drive]
What should I do? Do I reduce the size of /sda4? Also, I have six partitions. Isn't that the maximum permitted?
The options for modifying each partition are:
New partition size in megabytes (e.g. expand / reduce). Use as (e.g. ext2, ext3, ext4). Format the partition (check box or leave blank). Mount point (e.g. /).
I would appreciate some advice as to the best solution.
