ubuntu 9.04, not recognizing windows during installation

sharathg786 · 06-05-2009, 01:29 PM

Hi,

I have installed previous versions of ubuntu, but never has it missed recognizing my windows installation. I'm trying installing ubuntu 9.04, but during partition stage of the installation, it's not showing the option of installing "side by side".

Instead it's saying that "No other operating system is found on this computer" Please help me on this, if I'm missing / doing anything wrong.

Here is the output of fdisk -l:

Code:

Disk /dev/sda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sdb1               1       19457   156288321   42  SFS

As shown, I have two HDD, one with 40 GB (where I want both of the OS's) and the other is 160GB HDD. I previously had slackware on /dev/sda3, and my /home partition as /dev/sda7

what version of Windows is installed? Make sure your Windows install was cleanly shutdown: sometimes the unclean flag on the filesystem causes weird errors.

I'm running windows XP SP2, I have made sure there was a clean shutdown.
(But, yes the first time when i tried to install, I remember windows was not properly shutdown

)

I usually insert the ubuntu disc while running windows and then reboot. I checked with the md5sum tool, if the contents(.iso) were downloaded correctly, but no problems with that too.

Maybe it no longer scans FAT. Been too long since I haven't used NTFS.

It seems that nobody has faced this problem (after much googling), guess I have to do it the windows way... re-install windows and try again (I hate doing this

)

Just go ahead and install Ubuntu 9.04 to whatever partition you want. I'm guessing you want to install to /dev/sda3 since you said that /dev/sda7 was /home. Then just add this to the end of Ubuntu's /boot/grub/menu.lst:

Code:

title           Microsoft Windows XP Home Edition
root            (hd0,0)
savedefault
makeactive
chainloader     +1

Replace the (hd0,0) with whatever partition you have XP installed on. Remember that grub counts partitions starting from zero.

That's the problem, I get to see the partition table only with the fdisk -l command (running ubuntu live session) and not during installation.

I only get two choices,
> wipe the selected harddisk (sda / sdb) and install ubuntu
> manual partition

if i choose manual and select sda(where windows is installed), its not showing my existing partition table, instead it says there's no OS found, that means i can either choose to install ubuntu at the start OR at the end of hard disk /dev/sda

do you see it with partition editor on live cd?
if so try making your partitions in advance.

*partition editor=system-administration-partition editor
