Partition / Extended : Logical Drives

This is a really useful tutorial and thread, and having read through it I'm about ready to go ahead and convert my C: drive to an extended partition so I can have logical ones for my personal data (after I've done some backups !).

There's one thing I find potentially confusing though. I've got an HP laptop running W7 Home Premium 64bit, which came with 4 primary partitions, like several other people's laptops in this thread. As it has a separate 200Mb System partition (active, primary) I assume all the necessary boot files are on there, rather than on C: as they used to be. But what seems ambiguous is that the C: drive is labelled Boot, Page File, Crash Dump, Primary Partition. That almost implies that this drive also contains boot files, or am I just misinterpreting it ?

Hello Bare Foot Kid! Thank you for your tutorial. I have a question. Here is my situation.

Can i use all your tutorial steps for disk E:?

Sincerely yours, Ravil.

Thank you! I have data on it. My portable hdd was borrowed. As soon as I get it I'll save all data from disk E: on it, and will do exactly what you advise. I will necessarily keep you in touch. Thank you again for quick and full answer!

Sincerely yours, Ravil.

Hi, Bare Foot Kid! I did it. Everything worked correctly. Thank you very much!

Hi there sir, I followed your tutorial properly and I have been able to make extended partitions of my C drive thanks to you. I have an HP G6 2005AX which also gave me four partitions by default.
Anyway. I have a few quesions:

I hope nothing is different, now that my C drive is not a primary drive but a logical one. Does it make my computer a little slower? Because I am feeling a very slight lag.

Secondly will I be able to install windows 8 if I make another extension or partition of my C drive. Will windows 8 be installed in it? I mean I want a dual booting system, with windows 7 and 8 as well.
If not then what should I do to be able to install another OS with these current main 4 partitions.
Thanks

So this means that I can install windows 8 even on an extended partition right?
Secondly I did not understand what you mean by "Don't install using your windows 7 desktop"?
Plus can you guide me to some good tutorial where I can learn how to install a second OS?
