Whenever I boot Ubuntu, I get a message that it cannot mount my windows partition, and I can choose to either wait, skip or manually mount.

When I try to enter my Windows partition through Nautilus I get a message saying that this partition is hibernated and that I need to enter the file system and properly close it, something I have done with no problem so I don't know why this happens.

Here's my partition table, if any more data is needed please let me know.

I am trying to change the default folder icon, so I've googled a little and found out that I can do it ub

/use/share/icons/my_theme/places

Problem is that under 'Places' the are numerous folders

16 22 24 32 48 64 96 scalable

So, what folder do I need? They all have folder.svg in them so I'm not sure what to change.

Also - my icon is a .png file, how do I convert it to .svg? Thanks

A few simple questions for a total beginner:

1)Why use DHCP? I am running a small home-network: 1 desktop computer and twp lap-tops. What is the big advantage in DHCP for me? What configurations does it save me from doing?

2)I read here the following paragraph:

The Dynamic Host Configuration Protocol (DHCP) is a network service that
enables host computers to be automatically assigned settings from a server
opposed to manually configuring each network host

Who provides that service? Is it my ISP, a local program or a local hardware (like my router)?

Also, what configuration files will be edited as a result of using DHCP?

Thanks!

I read This manual and I'm a little confused. This is what I don't undetstand:

When your system tries to resolve a hostname to an IP address or determine the
ostname for an IP address, it refers to the /etc/hosts file before using the
name servers

So:

1)When DOES the system tries to resolve a hostname? To my understanding its when a datagrams's header specifies a hostname, am I right?

2)Why does it refer to hosts before resolv.conf?

3)After the hostname is resolved, the system turns to the routing table?

this isn't programming at all, but I've seen related topics so I thought why not. I am using ubuntu and currently trying to learn basic networking. I read a lot of theory, so I understand the terms (gateway, netmask etc...) but I can't seem to understand my own network at home. I have a router that serves my laptop (wireless) and my desktop computer (ethernet). When I run route in my desktop computer this is the output:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.0.0        *               255.255.255.0   U     1      0        0 eth0
link-local      *               255.255.0.0     U     1000   0        0 eth0
default         RTA1025W.home   0.0.0.0         UG    0      0        0 eth0

I can't understand it. I know the table specifies routing rules, I just can't understand those rules. An example would be highly appreciated: if I send a datagram to another computer on my home network, the first rule should match right? What column specifies where the datagram is redirected to?

Also, just to make sure, if I am trying to reach a website then all datagrams are directed to my router, right?

Also, what is link-local? It is defined in my /etc/networks file, I just don't know what that is.

I hope I was clear with what I am trying to understand, if not it's only because I'm a complete novice. Thanks anyway!

EDIT: to make it clear, I did read man route. As far as I understand: Destination refers to the destination of the datagram currently being routed. The same goes for Gatway and Genmas. That's great but what I don't understand is where will it be routed to? That's what I am trying to understand
