Installing a Dual-Boot with Windows and Ubuntu

choose "Manually edit partition table" from the menu. click next. Choose /dev/hda6 (or /dev/sda6 if you have a SATA HDD) for root partition ("/")

sorry, I don't get it. Here is what I did:
1. On the WELCOME part - English
2. WHERE ARE YOU - Zagreb
3. KEYBOARD LAYOUT - Croatian
4. PREPARE DISK SPACE - so here we have:
a) Guided - resize
b) Guided - use entire disk
c) Guided - use the largest continuous free space
d) Manual
5) I used Manual and now the EDIT PARTITION is showed
- I clicked the partition where I would like to install Ubuntu
- now this is my problem, I don't know which to choose:
a) NEW PARTITION SIZE - ok, here I used the maximum
b) USE AS: ext3, ext2, reiserfs, jfs, xfs, fat16, fat32, nfts, swap, dontuse - which to choose?
c) MOUNT POINT: /dos, /windows - also which to choose?

These are probably basic questions but I really couldn't find how to pass this point anywhere else.
thanks

i assuma you will use the partition which is 18,6 GB. From the 5th step:

5)Right click the partition (18,6GB)
a) set new partition size to 18 GB
b) use as :ext3
c) write mount point : /

6) then click ok. now we have set the linux partition. we have to use a swap partition too. Continue
7) You will see an unallocated partition at the end of the disc (~600 MB). Right click on it and follow these
a) set new partition size whatever possible ( ~600 MB )
b) use as : swap
c) leave blank the mount point

accept to continue. it will ask to really format, say yes.

At the end you will get an information dialog which tells you the installation configuration. you have to something like these:

format /dev/hda6 ext3
format /dev/hda7 swap
grub on (/dev/hd0)

if it is ok then click to continue.

Thanks, you are really helping me, but now a new problem occured. Everything was going well, the installation started and came to about 95% when it said some grub couldn't have been installed and the installation was canceled. Do you know what it might be?

can you please write here what you see at the last step before installing process starts (information about your installation type - the last window)

(and there must be a button at that information window named "Advanced", click on it and look if grub is set to hd0)

ok, I don't know how, but this time it worked. So, now I have Ubuntu installed, at least that's what it said. The thing is, I don't know how to start it. When I start my computer it immediately starts windows, doesn't ask anything. I really hope you can help me with this (I hope) last problem.

ok, as i see grub (the linux bootloader) has installed on another partition (probably begining of the root partition). Boot up with your ubuntu cd and do the same steps but at the last step (where the installation information is given) you have to set where grub will be installed. Click on Advanced button and change as "grub will be installed to hd0"

If it doesn't work please post the installation info at the last step

I did so the last time, it is in hd0

ok, please boot up with your ubuntu cd and open a terminal and type this command:

cat /etc/fstab

then post the output here. And please post the installation info at the last step.

terminal says:
unionfs / unionfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda2 swap swap defaults 0 0

I didn't install it again, but here's what the installation info at the last step was:
partition #1 on SCSI1 (0,0,0) (sda) ext3
partition #2 on SCSI1 (0,0,0) (sda) swap

Advance = (hd0)

sorry i am late to answer but i have to sleep :)

oh you have a SATA HDD! (sda). then grub must be installed to:

sd0

and so I tried again.... now with sd0. It said it couldn't install it, fatal error again, like the first time with hd0. Thanks for your help, but I'm really starting to wonder if I am ever going to complete this installation :-S

have a look at here:

may be virus warning is enabled in your BIOS. have a look at that setting and make sure it is set to OFF.

there is a good video tutorial here:
