I've never used unetbootin on windows but I'm surprised by the message you got on boot. I would not expect to see unetbootin in the boot menu as an option as it is simply software used to create bootable flash drives and not any kind of operating system. Or was that a typo and you saw Ubuntu in the menu and not unetbootin??

The part about being installed to hda2/sda2 could be problematic. If you already have windows 7 and Fedora installed you are probably using at least 3 partitions. How many physical hard drives do you have? How many partitions do you have on each? Since you say you have Fedora installed, I would suggest you boot it and open a terminal, log in as root and run this command: fdisk -l(Lower case Letter L in the command) and post the output here. I would expect your sda2 partition already has windows or Fedora on it.

Did unetbootin show any errors when you ran it? Did it complete and ask if you wanted to reboot? Did you boot from the flash drive created with unetbootin?

yancek, I have verified what you told. It asked for those options only which I wrote in my last post. First it asked me for one among the 2 options:
Fedora
other
Then, I pressed other.
Then, it asked me for Windows of UNetbootin.
i selected UNetbootin. Then it asked me to press 'Esc' key if I want to enter menu. I pressed 'Esc'.
Then the menu shown was a below:
1)UNetbootin
2)Help
3)Try Ubuntu without installing
4)Install Ubuntu
5)Check disk for defaults
6)Test Memory
7)Boot from 1st hard disk

Earlier I had tried by selecting both the options number 3 and 4. Finally I got the same error what I told you earlier.
Now, just I selected option number 7. and I got something similar to the window where we give unix commands. I checked by giving 'ls'. command 'who' didn't work. Then I had to forcefully shutdown my laptop directly by pressing the switch/boot button. Then when I started windows , it showed some error and then windows rectified it. (This i wrote just like that which may not be required to pay attention)

I am trying to reply to your other queries:
I have 1 physical hard drive only that is inbuilt with the laptop.
Now replying to your question on partition:---- I think there may be only 2 partitions. Because 1st Windows was installed and then when I installed myself Fedora, I provided a partition for it. So, 1 partition for windows and the other for Fedora.Now, in my windows I have c and d drives. Approximately, 40 GB space is allocated for C drive and 40 GB for D drive. And my Fedora also has 40 GB ( I think ). My total hard disk space is 120 GB. (40 * 3 becomes 120)

Unetbootin didn't show any error as far as I remember. YES IT COMPLETED PERFECLY BY FOLLOWING 4 STEPS AND THEN ASKED ME TO REBOOT. This I have mentioned in my earlier post also. Also, as mentioned earlier , I did 'frugal install', i.e. directly on my hard disk. i didn't use any flash drive or any external thing.

Please find attached the output of the command.

Hoping an early reply.

Unetbootin is designed to install a system to a flash drive, I don't know that it will work for what you are trying to do.
Your fdisk output shows 3 windows partition, an Extended partition which contains a small Linux boot partition and a large LVM partition which I would expect to contain Fedora. So my question now is, where in those partitions were you trying to install Ubuntu?

The menu you refer to above is what one would expect to see from a syslinux boot menu.
You didn't mention which Fedora you are using so we don't know if you have Grub Legacy or Grub2 installed with Fedora.
I haven't done any frugal install for quite some time so don't really know what one would expect.

Yancek when i was installing ubuntu 12.10 , i suppose it was in partition /dev/sda2

i am installing ubuntu 12.10 and the Fedora which is already there is Fedora 9 version 2.6(sulphur)

Hope to hear from you soon

The partition information you posted above shows sda, sda2 and sda3 as windows partitions so if you install Ubuntu to sda2 it will overwrite your windows on that partition. There is a wubi installation which will install Ubuntu inside windows as a program which could work. Is that what you are trying to do? Otherwise, you have nowhere to install Ubuntu as all your partitions are used.

Oh great Yancek, i think you have caught the right point.
No i am not trying to install inside windows. Like i have installed Fedora, same way i wanted to install ubuntu 12.10 on hard disk. As all my partitions are used, can that be reason why Ubuntu was not getting installed although momentarily while installation it messaged that it w'd be installed in sda2? it didn't ask me to choose the hard disk space where i want to install ubuntu and then it got stuck and not proceeding ahead.
OK Yancek, now what i wanna do is that i will remove Fedora which is already installed and i think i have allocated a space of 40 GB to it. in it's place i w'd install ubuntu 12.10.
SO, Yancek please show me way how to remove Fedora. And after it's removed shall i install ubuntu the same way. But as earlier it didn't ask me to choose the hard disk space, may i expect this time it w'd ask me for that. Becz this time also if it doesn't ask me and by default takes any on its own, then that w'd be a problem.
Hope to hear from you soon.

Hi Yancek, this is in addition to my previous post just above.I am giving you details of what was happening while ubuntu installation.
After clicking "install ubuntu" I entered 'language selection'. It asked for internet connectivity and then i clicked continue. Then it showed something like this:- " your medium of installation w'd be /dev/sda2. YOu may not be able to resize, increase, decreasee the partition but you can ...........".

Then a next window which came is what of our concern:-
Heading was : Installation type

It had table showing what I write below :: (i wanted to insert a table below but don't find any option here for that)

Device-----------------------------------------------------Type----Mount point------Format? ---------Size--------used

/dev/mapper/VolGroup00-LogVol00----------------------------ext3----------------------*---------------33789MB-----Unknown

/dev/sda6--------------------------------------------------*------------------------*---------------35927MB-------unknown

____________________________________________________________________________________________________ _____________________

There was one dropdown menu :
Name of the menu: Device for boot loader installation

The options in the dropdown list are:

/dev/mapper/VolGroup00-LogVol00 Linux device-mapper (linear) (33.8GB)
/dev/mapper/VolGroup00-LogVol00 Fedora release 9 (sulphur)
/dev/mapper/VolGroup00-LogVol01 Linux device-mapper (linear) (2.1GB)
/dev/sda ATA WDC WD12 00BEVS-2 (120.0 GB)
/dev/sda1 Windows 7 (loader)
/dev/sda2
/dev/sda3
/dev/sda5
/dev/dm-0

____________________________________________________________________________________________________ ______________________

In the 1st table, there is a column named "Format?". Under it check box is there. if i click on that (for those rows where "Type" is mentioned like ntfs ext3) a box w'd pop-up named "Edit partition".
Below that a drop down list named "use as:". The list of drop down shows the below option:
Ext4 journling file system
Ext3 journling file system
Ext2 journling file system
....
.....
....
....
Fat16 file system
Fat32 file system
swap area
physical volume for encryption
do not use the partition

By default the last option was selected : do not use the partition
I think because of this it was not getting installed.

Also, there is one more check box named "Format the partition". If I check this it should install
____________________________________________________________________________________________________ _________________

Please tell me which options to be selected for the 3 menus below:
a)for device, i think I should select the 1st one:
/dev/mapper/VolGroup00-LogVol00
/dev/mapper/VolGroup00-LogVol00 ext3 * 33789MB Unknown

sda6 can't be opted because the format option won't work here as "Type" is also not mentioned.

b)for "Device for boot loader installation"
by default "/dev/sda ATA WDC WD12 00BEVS-2 (120.0 GB)" was selected

c) what to select in 'format?' as clickinig it pops up a window to be filled



I am not trying by usb as it may give the same issue
(its not user friendly to write here as the forum is on its own formatting my text. contiguous spaces are getting compressed. difficult to write here)

After the language selection, you should see 'Preparing to install Ubuntu' with the available space needed and checked if connected to the internet. After that, you should see Installation type where you select Something Else and you will get the "Allocate Drive Space" window.

From your previous fdisk output, sda5 would appear to be a boot partition and sda6 the LVM partition for Fedora. The simplest thing to do here would be to select sda5 to highlight it and then click the Delete tab below the main window. Do the same for sda6. Then you should see that as free or unallocated space. Click on free space in the main window to highlight it then click the Add tab and you will get the Edit partition window. In the new size, use all but 2GB (that will be used later for swap), under use as select ext4 journal fs (this is the default for the current Ubuntu), click the Format box, and click the down arrow on the mount point tab and select '/', or enter / as it is the symbol for root of the filesystem. Click Ok and select the remaining free space by highlighting it in the main window and selecting 'swap' in Use as.

If you select Format as ext4 above, it will format the partition(s) on which Fedora is and install Ubuntu there.

The Device for bootloader installation should be /dev/sda. This will be the master boot record and it will overwrite the current windows/Fedora entry in your mbr, not sure which you have. It should also create a menu entry for Ubuntu and windows so you can select either on boot. If you want to keep windows bootloader in the mbr (do you have it there now?) then select /dev/sda5 for bootloader which would be the Ubuntu partition. If you do the latter, you will need to manually create an entry in your windows boot file to boot Ubuntu. I have no idea how to do that. I expect you are currently using the Fedora bootloader to boot Fedora and windows. If so, the simplest thing would be to install the Ubuntu bootloader to the mbr, /dev/sda.

Oh I made a big mistake Yancek. In my previous post by mistake I have typed 'ntfs' as the type for /dev/sda6 but the column is blank for sda6. So, it shoud be

/dev/sda6-------------------------------------------------------*---------------35927MB-------unknown

Type for /dev/sda6 is blank. I didn't go through your post but I think you might have taken care of that.
Thanks. I w'd go through your post shortly

Thanks Yancek, I too think I am using Fedora boot loader to boot Fedora and Windows. When I boot my system, it gives a few seconds for me to choose an option among the following:
Fedora
Other
If I don't give my input in 5 secs of so, it boots Fedora by default. So, it should be Fedora boot loader.

Also before I go by your way, just w'd like to know if there is a way (if easy) to reduce the space which currently Fedora is using. It is using over 35 GB or so. If you can reduce this space and make available some free space, I w'd like to install Ubuntu there and hence keep Fedora also. This I say because suppose the new reinstallition over the former one does't work well, my work w'd stop. So, to be on safer side please say if new space can be (easily) available. Later when ubuntu works fine I w'd remove completely the old version of Fedora 9 (sulphur) which I am using.

Also, I have read of installing Linux inside windows. Is it easy and doesn't require virtualization? Because virtualization won't work on my system because of low memory 1GB. So, if I install within windows, for entering Ubuntu I don't need to enter Windows? Please clarify this.

Your Fedora partition (sda6) is LVM. I don't know how to resize LVM partitions as I've never used it but it is obviously possible to resize/shrink it. I would start by using the Search function here at LQ and searching 'resize LVM partition'.

OH yancek, I couldn't proceed. I deleted sda5 but couldn't sda6. Then I clicked on a "Revert" button which had undone the change and I was back to my original.
As I had already mentioned in my earlier post that the field of /dev/sda6, there is no type mentioned. The below buttons are disabled for this partition sda6. Doubble click doesn't popup a new window which pops up for other partitions for which type (ext3 or ntfs) is mentioned. when I selected sda5, the below bottons were enabled and I could delete it. After that , the partition was shown as free space. Then I saw the other partition sda6 was changed (name change) to sda5. But no buttons were active for this.

I AM STUCK, WHAT TO DO, HOW TO PROCEED.
WAITING EAGERLY FOR YOUR PATH

I've never used LVM so can't help. You could use the search function here at LQ to see if you can find info. I know I've seen posts on it. Check the site below, might help:

Thanks Yancek for all your useful assistance.

Just a thought sprung up my mind. Can I work on my Ubuntu if I install on a flash drive/pen drive or a memory card within my cell phone. I had worked on commands like mkfs, mount , etc. with my memory card (2GB) in cell phone.My computer recognizes it as 2nd hard disk. My 1st one is named sda and this one of phone is sdb.
HOw much space of this 2nd disk is reqd. But make sure I don't want any virtualization,it should be directly from hard disk.
