Hi everyone, please have a look at the screenshot.

http://yfrog.com/4vscreenshotyyp

(i am about to create the home partition)

As you can see from the screenshot, i am having 2 Hard disk- 500GB + 160GB

I am using the 500gb to install Ubuntu. It has totally 3 partions (including an extended).
The third partition is actually an unallocated one (10gb) in which i intend to install Ubuntu.

After selectin the /,swap.. i am not able to select the home (as shown in screenshot). After hitting the forward button the installation process continues however..

After everything is done, i am not getting the Multiboot options (like Ubuntu,XP etc) and the system just boots with XP .

What do i do?

Thanks
Abhay

Your description of what you want to do and that partition table are quite different. You realize that you're only allocating 2GB to your / partition in that picture? Same for swap.. 2G for swap. Sidenote, for swap you want double your system physical memory.

Which drive is your Windows install on? That picture implies you have a giant NTFS partition on your 500GB drive, one small NTFS partition (most likely recovery partition?) as well as the entirety of your 160GB drive.

You are allowed 4 primary partitions so with your two NTFS partitions, your ext4 / partition and your swap partition you have hit that limit already which is why it will not allow you to add /home to that 6GB partition. You need to redo it with an extended partition. Furthermore, why are you devoting only 2GB to / and 6GB to /home? I would rethink that as well.


Best practices you'll want to make a 100MB partition for /boot, a swap partition that is double your system memory and then the rest can be allocated for / or however else you want to carve up your drive.

As far as the bootloader, you need to install GRUB to the MBR which should be an option in the installation wizard

The windows is in /dev/sda1

hmm let me clarify..

I am having basically 2 hard drives 500gb and a 160gb. 160gb can be discarded as of now (as i intend to use it for storage only)

In the 500gb hardrive there totally 3 partitons , C: ~42gb (OS drive )[/dev/sda1 in the pic] D: ~420gb,(/dev/sda5) and lastly 10gb of unallocated space(which actually doesn't show up while in windows)

I intend to use this 10gb of unallocated space for Ubuntu.So in the screenshot you can see that i am trying to create / , swap , and home in the 10gb space.

I am having no other option other than installing in that 10gb unallocated space.

PS: There's already an extended partion in the 500gb Hardrive.

Sorry for the confusion

How do i install Ubuntu in that 10gb partition? Also i am having 4gb of RAM.

Thanks

Yeah I mean I understand the situation but it doesn't appear that there is an extended partition created. Bring it up in fdisk via the command line instead of this wizard and see if you can print out the partition tables to verify you actually have created an extended partition. You are unable to do anything with that last 6GB because based on that picture you've hit the 4 primary partition limit. I would also rethink having 6GB for home and only 2GB for swap.

With such a small amount of hard drive space, why are you creating separate partitions for "/" and "home"?

As for why it isn't working, it may have to do with "swap" being listed before "home". Try "/" and "swap", or "/", "home", and then "swap".

Also, since you have 4GB RAM, just use 500MB for swap.

Except if you don't have at least as much as physical RAM, you can't hibernate.

Sidenote, for swap you want double your system physical memory.
Now you tell me, now that I only allocated 4GB on a 4GB system. :\ :p But really, I've been surprised how much swap gets used.

True, but I never hibernate anyway. In the OP's case, using 4GB of swap for 10GB total hard drive space would be beyond foolish, and even 2GB is overkill since it isn't his primary OS (doubt he would ever max his RAM).

Thanks for all the replies guys.
So , what would be the best/safe way to Install Ubuntu in that 10gb . I am already having 2 primary partitions and a 4gb of RAM
