Samsung N150 Plus netbook for Windows and Linux

Quick look at the hardware

The N150 Plus comes with 10-inch screen resolution 1024x600, 250 GB disk, Intel Atom N450 1.66GHz processor, 3 USB ports (one with "permanent" power), Fast Ethernet port, and VGA HD-15 port. Weight with battery (without power-brick): 1.20 kg.

Initial view of the disk

2011-03-25. I first booted into a Linux installation system (it happened to be Fedora 14) and did Ctl-Alt-F2 just to view the layout of the netbook partitions as supplied. Note that Fedora 14 fdisk uses the -u option by default, so Start and End information is in sectors. I then mounted each partition read-only and checked the used space and contents. I then just rebooted without installing a linux system at this stage.

The partitions look like a Recovery Partition on sda1, a boot manager partition of exactly 100 MiB (sometimes called the BitLocker partition I think) on sda2, a Windows C drive on sda3, and a D drive on sda4.

First Windows boot

I then booted the netbook, without a network. The netbook boots into Windows 7 Starter, asks for a few details: language, localisation, name of primary user and computer, initial Windows Update setting, and then goes into an Install process which takes 20 minutes. Then there's a prompt from Easy Partition Manager to choose relative C and D drive sizes. I chose the minimum C: drive size of 40 GB, making the D: drive 172 GB. This operation took about 1 minute, after which Windows was available. As the partition manager recommended a reboot, I did this straightaway. A process then ran called Easy Speed-Up Manager which took a bit over 15 minutes.

Quick look after first Windows boot

Rebooted into a linux installation system again on CD, to see what's happened. The Easy Partition Manager has converted the C: drive from exactly 40 GiB to exactly 41 GiB, which is an odd thing to do after I asked for 40, and the D: drive is 171 GiB. It has conveniently created an extended partition for us at sda4, which contains just one logical partition sda5: the D: drive (which is empty). At a quick glance, again mounting read-only, partition sda1 appears unchanged, partition sda2 now has a BOOT/BCD.LOG file, and partition sda3 as the C: drive has been updated (maybe to include new programs) by the first-boot installation.

Installing Linux

Installing Linux was very straightforward. I booted a Fedora 14 CD (using my external CD/DVD drive). This works in GUI mode without problems. I normally do partitioning by hand using fdisk, so I did a Ctl-Alt-F2 and used fdisk to delete the sda5 partition (D: disk, empty anyway), and to give me additional partitions for Linux, as well as a 80 GiB area for a new D: disk. I will try the XFCE window manager at first, and try KDE as well if XFCE is very responsive.
